Les Numéros de Demain

Les Numéros de Demain is a playground for mathematics and probability. Fifty years of French Loto and EuroMillions archives become a retro-futuristic almanac that plays with the delightfully absurd idea of cheating chance, then shows why no historical record can predict a draw.

Value proposition

It is the kind of product exercise I enjoy: taking the mathematics of chance seriously, then making the subject approachable through an interface inspired by the sports almanac in Back to the Future. The visual joke invites a smile; the method reminds us that every valid grid has the same odds.

The interface plays with the fantasy of an almanac that could reveal tomorrow, then immediately restates the probabilistic limits of every projection.
Frequency and gap map for the 49 French Loto numbers in Les Numéros de Demain
Frequencies and gaps describe past draws without forecasting the next one.
Generator for ten diversified French Loto grids with profiles and originality scores
The generator varies combination structures without claiming to improve their odds of winning.
Backtest chart comparing the frequency strategy with the expected result of randomness
The backtest replays draws in order and shows that the strategy remains at the level of chance.
