Inside Scratchcards · Online Instant Games

How Do Online Scratchcards Work?

Online scratchcards look as though you are uncovering, tapping, spinning or choosing your way to a result. But in many official lottery instant games, the prize outcome is already fixed at the point you buy that individual play.

The system randomly determines an outcome, records it against your purchase and then the game interface reveals or plays out that result. The animation can be interactive without your later clicks changing whether the play wins.

Quick answer

Online Scratchcards Are Digital Instant Lottery Games, Not Physical Tickets on a Screen

There is no physical card travelling from a printer to a retailer. Instead, an online instant game runs through a lottery's digital gaming system. The player purchases one play, the system determines and records its outcome, and software presents that play through graphics, sounds and interactions.

Different countries use different names: Instant Win Games in the UK and Ireland, Instant Kiwi Online in New Zealand, and terms such as online instant games or eInstants in parts of the United States.

The most important point

The Animation and the Prize Decision Are Not Necessarily the Same Event

The Irish National Lottery explicitly says its Instant Win Game outcome is predetermined at the point of purchase and that animations are for entertainment. Lotto NZ similarly says Instant Kiwi Online outcomes are randomly determined by the system when the player clicks Buy.

That means the dramatic moment where a symbol lands, a digital panel is scratched or a bonus round opens can be the reveal of the result rather than the moment the prize is chosen.

From Buy to result

What Happens When You Buy an Online Scratchcard?

The precise software architecture differs between lotteries, but documented instant-game systems follow a recognisable sequence.

1

Your Account Is Checked

The operator confirms that the play can be purchased under its account, age, location, wallet and play-limit rules.

2

The Purchase Is Accepted

The stake is committed and the operator creates a record of that individual online play.

3

The Outcome Is Determined

For documented predetermined instant games, the gaming system randomly selects the prize outcome at the point of purchase.

4

The Outcome Is Stored

The system retains the authoritative transaction and result so the play can be recovered, audited or investigated if something goes wrong.

5

The Game Plays Out

The website or app uses animation and interaction to present the already-recorded outcome according to that game's rules.

6

The Prize Is Credited or Claimed

Smaller prizes can be paid into an online account automatically; larger prizes may trigger identity and formal claim checks.

When is the result decided?

Is an Online Scratchcard Result Already Decided Before You Start Clicking?

For several major lottery-operated systems, the official answer is yes — once the paid play has been purchased.

Ireland — Set at the Point of Purchase

The Irish National Lottery says an Instant Win Game outcome is randomly determined from all possible outcomes and is set at the moment of purchase. Its separate player guidance says animations are purely for entertainment and player actions do not influence whether a prize is won.

New Zealand — Determined When You Click Buy

Lotto NZ says the outcome of an Instant Kiwi Online game is determined at random by the system when the player clicks Buy. Its accessibility guidance is particularly revealing: players using Accessible Mode can press Buy and receive the outcome without experiencing the full visual gameplay.

Worldwide Security Standard

The WLA's current standard says most online games are predetermined and requires risk controls for games with predetermined winners. It separately applies RNG security requirements to chance-based digital games.

Important wording: this does not mean the lottery decided yesterday that “your next game will lose.” In the documented systems above, the result is randomly determined when the individual paid play is purchased, then fixed for that play.

Random vs predetermined

How Can an Online Scratchcard Be Random and Predetermined at the Same Time?

The two words describe different parts of the process.

Random Describes How the Outcome Is Chosen; Predetermined Describes When It Becomes Fixed

Imagine the system randomly selects one outcome when you press Buy. At that instant, the selection can be unpredictable and independently generated. Once selected and recorded, however, that specific play now has a fixed outcome.

Before purchaseYour individual play does not yet have the recorded outcome that will be shown to you.
At purchaseThe system uses the approved game probabilities and randomisation process to determine the outcome.
After purchaseThe result for that play is fixed, even if the animation still has several taps, reveals or bonus screens left to show.
Do your choices matter?

Does Where You Click on an Online Scratchcard Change Whether You Win?

Not where the operator's rules say the overall prize outcome is already determined at purchase.

Choosing a Box Can Still Change What You See

A game can respond to the order in which you reveal panels or choose objects. The interface can therefore feel genuinely interactive.

That Does Not Mean the Choice Changed the Prize

Ireland's rules specifically say players do not exercise skill or judgement in an Instant Win Game play and that animations do not necessarily represent the actual outcome-setting process.

The Game Can Be Designed Around a Fixed Target Outcome

Once the system knows whether the play is a win or loss and the applicable prize, the software can present a sequence of permitted visual events that ends consistently with that recorded outcome.

So the click can matter to the experience without mattering to the underlying prize. That distinction is the key to understanding many online instant games.

Does where you click on an online scratchcard matter? →

Why all the animation?

Why Do Online Scratchcards Have Bonus Rounds, Wheels and Choices If the Result Is Already Set?

Because the gameplay is the way the outcome is presented to the player.

Presentation

The Animation Makes the Result Understandable

Instead of simply displaying “you won €5,” the game can recreate the familiar suspense of scratching, matching, spinning or uncovering symbols.

Entertainment

Different Themes Can Use the Same Underlying Lottery Principle

An online instant game can look like a scratchcard, puzzle, wheel, sports challenge or mini-game while still being a chance-based instant lottery play.

Accessibility

The Full Animation Is Not Always Necessary to Establish the Result

Lotto NZ's Accessible Mode can give an Instant Kiwi Online player the outcome after Buy without requiring the full visual gameplay, reinforcing the separation between outcome and presentation.

Rules still matter

Not Every Online Game Must Work Identically

Some online games can contain multiplayer or skill-like elements. WLA therefore requires operators to assess the specific integrity risks of each game rather than assuming every digital game is identical.

The RNG

How Is the Random Outcome of an Online Instant Game Generated?

The detailed algorithms are security-sensitive, but current lottery standards explain what a compliant random-number system is expected to achieve.

The RNG and Game Engine Must Be Protected, Tested and Used Without Introducing Bias

The WLA applies its RNG controls to chance-based digital games. It requires protection against unauthorised access or modification and independent testing before deployment.

Random sourceThe system can use a true RNG or approved pseudo-random number generator depending on the architecture.
Game mappingSoftware converts the random output into outcomes that follow the game's approved rules and prize probabilities.
Independent testingTesting should check randomness, correct use of the RNG and whether the conversion from raw numbers introduces bias.

WLA guidance specifically mentions statistical testing, PRNG seeding and reseeding controls, fail-safe behaviour and mass-data testing to check prize-level odds.

A major difference from paper

Do Online Scratchcards Have a Fixed Pool of Winners Like Physical Scratchcards?

Often they do not — and this is one of the biggest mechanical differences between physical and digital instant games.

Physical scratchcards
  • A finite population of tickets is manufactured.
  • A fixed number of winning and losing tickets exists in that printed game.
  • Prizes can become depleted as winning tickets are sold and claimed.
  • Some operators publish remaining top-prize counts.
Many online instant games
  • Each purchase can be generated from approved outcome probabilities.
  • Ireland says its Instant Win Game prize pool is non-depleting.
  • Lotto NZ says Instant Kiwi Online uses a non-depleting ticket pool.
  • A previous player's win does not necessarily remove one physical winning ticket from future availability.
This is why “how many jackpots are left?” can work differently online. Do not automatically apply physical scratchcard remaining-prize logic to a non-depleting digital instant game.

Physical vs online scratchcards →

If the game freezes

What Happens If an Online Scratchcard Crashes Before You Finish?

If the outcome was recorded at purchase, losing the animation does not necessarily lose the underlying play.

New Zealand Can Complete the Ticket Automatically

Lotto NZ says that if an Instant Kiwi Online ticket cannot be completed for any reason, it will be automatically completed on the player's behalf. Its FAQ says this can take up to 15 minutes from purchase.

Ireland Can Resolve Purchased Plays Through the Central System

Irish rules provide for the Central Gaming System to play out purchased Instant Win Game plays in defined circumstances, including where a game closes before the player completes it.

The System Record Matters More Than the Animation

The WLA requires procedures for discrepancies between what appears on the customer's device and what is logged in the gaming system, including use of transaction logs, audit files or replay functionality for disputes.

Displayed result vs official result

What If the Online Game Animation Shows the Wrong Prize?

Digital games can suffer browser, device, software or communication problems, so operators need a rule for conflicts between the screen and the authoritative system record.

Ireland Says the Central Gaming System Determines the Outcome

Its terms state that all prizes must be validated by the Central Gaming System. If a prize displayed during or at the end of a play conflicts with the system record, the Central Gaming System determines the outcome.

WLA Requires Evidence for Online Game Disputes

The current security standard says lotteries should be able to investigate discrepancies using mechanisms such as replay functionality, transaction logging or audit-file investigation.

This is the digital equivalent of physical ticket validation: the visual layer is not necessarily the final authority when the protected system record says something different.
Testing the game

Who Checks That an Online Instant Game Pays the Correct Odds?

Security testing is supposed to happen before the game reaches players, not after somebody notices that the payouts look wrong.

Randomness Is Independently Tested

WLA requires independent tests and verification before deployment of RNG-based chance games, plus an ongoing policy for checking that the system continues to perform as specified.

The Online Game Itself Should Be Certified

WLA says dedicated online games should be tested to demonstrate integrity and correct prize payout throughout their lifecycle, with controlled game certificates and security-test reports.

Payout Performance Can Be Monitored

The standard calls for the game rules and overall payout percentage to be available to players and includes monitoring of payout percentage and prizes that exceed the rules.

Your online account

How Are Online Scratchcard Winnings Recorded and Paid?

With no paper ticket to present, the online account and gaming transaction become part of the claim trail.

Ireland

Irish National Lottery terms connect each play to the registered account and wallet. Lower instant prizes can be credited automatically, while larger amounts move through card, cheque or formal identity-verified claim processes depending on prize tier.

Virginia, USA

Virginia Lottery says online instant winnings up to specified thresholds are returned automatically to the player's wallet, with larger wins moving into automatic or formal claim procedures.

UK

The UK National Lottery offers Instant Win Games through registered online accounts and provides account tools for tracking plays and transactions, as well as spend, deposit and play limits.

Try-for-free games

Are Free Demo Online Scratchcards Using Real Winning Plays?

A demo can show how the interface behaves without being a genuine paid lottery play.

Ireland Says Try for Free Games Do Not Award Prizes

Its account terms explicitly state that no prize entitlement arises from Try for Free games. The demo teaches the gameplay but is separate from a purchased Play.

The UK Also Lets Players Try Instant Win Games Before Buying

The National Lottery's responsible-play information says logged-in users can try Instant Win Games for free to see how they work before committing to a purchase.

So a demo result should not be treated as evidence that “the next paid game would have won.” Demo play and paid play are separate transactions.
Physical vs digital

What Is the Biggest Difference Between a Physical Scratchcard and an Online Scratchcard?

They can create a similar reveal experience, but the moment the underlying outcome comes into existence can be very different.

Physical ticket
  • The result is created during secure game production.
  • The specific winner exists before the ticket leaves the factory.
  • The ticket then has to be packed, distributed, activated and sold.
  • Scratching reveals data already printed into that particular physical card.
Predetermined online play
  • There is no pre-printed physical ticket waiting in a retailer.
  • The individual outcome can be randomly determined when the paid play is purchased.
  • The system records that outcome electronically.
  • The visual game then presents the recorded win or loss.
Common misunderstandings

Six Myths About How Online Scratchcards Work

Myth

“The Prize Is Decided When the Final Symbol Appears”

In documented predetermined games, the underlying outcome was fixed at purchase.

Myth

“If I Had Clicked the Other Box, I Would Have Won”

Not where the game's rules say player actions do not influence the outcome.

Myth

“Predetermined Means It Was Chosen Before I Logged In”

In Ireland and New Zealand, the documented result is determined at the purchase of that individual play.

Myth

“Random and Predetermined Contradict Each Other”

A result can be randomly selected and then immediately become fixed.

Myth

“The Last Player Winning Makes My Next Play Worse”

Not in the non-depleting instant-game models documented by Ireland and Lotto NZ.

Reality

The System Record Is the Core of the Digital Ticket

Your purchase, determined outcome and prize entitlement exist as a controlled electronic transaction rather than as printing hidden beneath latex.

Frequently asked questions

Online Scratchcards and Instant Win Games: 12 Common Questions

Online instant-game rules vary by operator, so these answers distinguish documented examples from broader security principles rather than assuming every lottery uses an identical system.

How do online scratchcards work?

Online scratchcards, instant win games and eInstants are digital lottery games played through a website or app. In documented systems such as Ireland and New Zealand, the outcome is randomly determined by the lottery system at the point of purchase, then the on-screen game reveals or represents that already-set result.

Is an online scratchcard result decided before I start scratching or clicking?

For many lottery-operated online instant games, yes. The Irish National Lottery says the outcome is predetermined by its Central Gaming System at the point of purchase, and Lotto NZ says an Instant Kiwi Online outcome is determined at random when you click Buy.

Do my clicks or choices change whether I win?

Not in games where the prize outcome is fixed at purchase. The Irish National Lottery explicitly says its game animations are for entertainment and the player's actions do not influence whether a prize is won.

Are online scratchcards random if the result is predetermined?

Yes, those ideas are compatible. The outcome can be randomly selected at the moment of purchase and then become fixed for that individual play. 'Predetermined' describes when the result becomes fixed; 'random' describes how the result is selected.

Do online scratchcards have a finite number of winning tickets like physical scratchcards?

Not always. Ireland says its Instant Win Games use a non-depleting prize pool, so a previous win or loss does not change the next play's odds. Lotto NZ also describes its Instant Kiwi Online ticket pool as non-depleting. Physical scratchcards normally come from a finite printed ticket population.

What is the animation doing if the result is already decided?

In a predetermined game, the animation is the presentation layer that reveals or plays out the result recorded for that purchase. It can make the game interactive and entertaining without allowing the player's later clicks to change the underlying prize.

What happens if my internet disconnects halfway through an online instant game?

The exact recovery process varies by operator. Lotto NZ says an incomplete Instant Kiwi Online ticket will be automatically completed on the player's behalf. Irish rules also provide for the Central Gaming System to complete purchased plays in certain circumstances, so the recorded outcome is not dependent on finishing the animation.

Can an animation show one result while the lottery system records another?

It can happen if there is a technical discrepancy, which is why operators need dispute rules. Ireland states that if the displayed prize conflicts with its Central Gaming System, the system record determines the play. WLA security standards require procedures, logging and evidence for online-game result discrepancies.

How are online instant game random number generators checked?

WLA security standards require independent testing before deployment of RNG-based electronic and chance-based digital games, checks that raw random values are used without introducing bias, and controls over the RNG, game engine and system configuration.

Are demo or try-for-free online scratchcards real prize plays?

Usually not. Ireland's terms say Try for Free games do not award prizes, and the UK National Lottery also offers free trials of Instant Win Games so players can see how games work before buying.

How are online scratchcard prizes paid?

Payment depends on the operator and prize size. Smaller prizes are often credited automatically to an online wallet or account, while larger prizes may trigger identity checks and a formal claim process. Virginia, Ireland and New Zealand all use account-based handling for online lottery winnings.

Are online scratchcards the same as physical scratchcards?

They can look similar but the mechanics are different. A physical scratchcard's outcome is printed into a finite ticket before distribution. In many online instant games, the outcome is generated electronically at purchase and recorded against the player's digital play.
