Test lottery ideas against real draw history. Lottery Lab now includes live Set For Life number-frequency and pair analysis alongside Set For Life and Thunderball backtests, with more experiments added as the underlying draw history and rules are ready.
Completed draw data can show what would have happened. It cannot make a valid number combination more likely next time.
Each experiment starts with a clear question and uses completed draw history to answer it. Some tests replay number strategies and compare spend with prizes; others measure frequency, return gaps, number pairs and relationships within the archive.
Replay the five most-drawn main numbers through the comparable 1–39 era, test all 14 Thunderballs and compare the historical return with Thunderball’s theoretical return. You can also switch instantly between the hottest five, coldest five, a random line or your own five numbers.
Open the Thunderball backtest →Replay the five most-drawn main numbers through the completed Set For Life archive, test every Life Ball and compare ticket spend with historical winnings.
→Explore every main number from 1 to 47, compare any of the 1,081 number pairs and add a Life Ball to see historical frequency, return times and expected-versus-actual relationships.
→Compare the hottest five, coldest five, random lines and your own numbers across the current-format Thunderball era.
→Replay a six-number Lotto line through a comparable rules era and measure matches, ticket spend and historical return.
→Test valid main-number and Lucky Star strategies while keeping different EuroMillions rules eras separate.
→Compare playing every draw with entering only when the advertised jackpot crosses a chosen threshold.
→Replay valid number and jackpot-threshold ideas through comparable Mega Millions draw history.
→Start with the live Set For Life and Thunderball experiments. Set For Life now includes both historical backtesting and an interactive number-frequency, pair and Life Ball explorer.
If an idea can be replayed fairly through completed draw data, we can test it.
Measure how often a number appears, its average time between appearances, which numbers occur together and how main numbers combine with the Life Ball.
Compare the most-drawn and least-drawn numbers across the same completed draw history without treating either group as predictive.
See how much repeated play would have cost, what the line would have returned and the resulting net historical outcome.
Compare birthdays, consecutive numbers, repeated draw numbers and other common ways people choose lines.
Compare one draw, every draw, jackpot thresholds and other entry patterns using the same underlying results.
Compare a fresh random valid line with hindsight-selected hot and cold numbers across exactly the same Thunderball archive.
We set the rule first — for example, “play the five most-drawn main numbers through every comparable draw”.
The rule is applied only where the number matrix, draw format and prize structure make a fair historical comparison possible.
Lottery Lab reports matches, prize return, ticket spend and net outcome rather than selecting only favourable examples.
Lottery Lab is historical analysis, not number prediction. A number appearing more or less often in previous draws does not change the probability attached to a valid line in the next independent draw. Planned experiments are added only when the underlying results and rules can support a fair comparison.
