A maths playground for Singapore 4D & TOTO
Can formulas find patterns in lottery draws? Let’s test them honestly.
Mix skip analysis, frequencies, golden ratios, entropy and more into your own predictions, then see how each formula would have done on past draws, side by side with plain random tickets. It’s for fun and learning: no formula beats a fair draw, and we show you why.

TOTO backtest
Is TOTO golden?
Golden-ratio sequences picking six numbers. Beautiful maths, but does it win?

Friends that travel together
Pairs that came out together before: are they more likely to again?
