Digit Contracts Explained — Analysis scheme pro

Matches wins when the final digit equals the digit you selected: 1 in 10 outcomes, a 10% reference. Differs is its complement and wins on the other nine digits, a 90% reference. A digit appearing unusually often or rarely is a historical observation only — it is never "due". The Matches/Differs scanner compares each digit's observed rate against these exact values.

Over wins when the last digit is strictly greater than the barrier; Under wins when it is strictly lower. A digit equal to the barrier wins neither side. Barriers run 0–8 for Over and 1–9 for Under, so the theoretical probability changes with every barrier you pick — for example Over 5 covers digits 6–9, four of ten outcomes. The Over/Under scanner lists the eligible and excluded digits for the selected barrier alongside theoretical and observed rates.

Even covers 0, 2, 4, 6 and 8 — zero counts as even — and Odd covers 1, 3, 5, 7 and 9, each a 50% reference. The Even/Odd analyzer shows parity streaks and meters, but a long run of one parity is not evidence that the other is now more likely: ticks are independent.

With the right baseline in place, the question becomes how much a deviation matters. Sample size, confidence intervals, chi-square uniformity and agreement across window sizes all shape that answer — see the statistical engine and the strategy guide. Statistical deviation is not predictive evidence.
