Martingale
Double after each loss on an even-money bet. It produces many small wins and occasional large drawdowns.
Risk: Fails against finite bankrolls, table limits, and losing streaks. It does not remove the house edge.

Use a number line, bet the sum of the first and last values, cancel numbers after wins, extend after losses.
Risk: Can escalate quickly during losing sequences. Best presented as a bankroll simulation, not an advantage play.
Increase one unit after a loss and decrease one unit after a win.
Risk: Smoother than Martingale, but still cannot overcome roulette's expected loss.
