Fisher Roulette Strategy

Rule as described

The Fisher progressionstrategyProgressionAny rule that changes the stake based on previous results. Negative progressions raise it after losses, positive after wins.Read full → repeats an even-money base wager for four losses, then triples it for the next four, then triples it again for the next four; a win resets the stake to base. With a $5 base, that is four $5 wagers, four $15 wagers, then four $45 wagers.

Progression table

The table shows the wager required after an uninterrupted loss count under the four-wagers-per-level rule.

Worked example

Start with $5 on redbetRedEven-money bet on the 18 red numbers. French: rouge.Read full →. Four losses cost $20, so wagers five through eight are $15 each. Eight losses therefore cost $80; the ninth wager is $45, not a stake made immediately after the fourth loss. If that ninth bet wins, it gains $45 but remains $35 behind across the run. A win resets the next stake to $5, but it does not retrospectively recover every prior loss.

Cost and risk

After 12 losses, $260 is gone and the next $135 wager would leave the sequence $125 behind even if it wins.
