ℹ How this betting test works
The simulator watches the roulette history for an unusually strong run or percentage of one colour. When a trigger is reached, it bets against that colour imbalance on the next spin, using one colour bet plus two 12-number columns.

When BLACK triggers
The next bet is RED + Top column + Bottom column. The Top column is the red-heavy column (8 red / 4 black), while the Bottom column is balanced (6 red / 6 black).

When RED triggers
The next bet is BLACK + Middle column + Bottom column. The Middle column is the black-heavy column (8 black / 4 red), while the Bottom column is balanced (6 red / 6 black).

Why three bets?
The colour bet pays 1:1 and each 12-number column pays 2:1. All three components use the same progression stake. At progression step 4, for example, the simulator stakes 4 on the colour + 4 on the first column + 4 on the second column = 12 chips total.

Possible result types
Profit: enough of the three components win to finish the spin above the starting stake. Push: the combined three bets finish exactly 0. Partial loss: the combined result is below 0 but not all three stakes are lost. Full loss: all three components lose, including when zero lands.

Triggers & progression
You can trigger from a consecutive colour streak, a colour percentage over a chosen history length, either condition, or both. The default progression is 1, 2, 4, 8, 16, 32, 64, 300 per component. The Profit / Push / Partial Loss / Full Loss controls decide whether that progression resets, repeats or advances.

This is a simulation/testing tool. Roulette outcomes are independent, so a streak or historical colour imbalance does not make the opposite colour more likely on the next spin. Progressions can increase stakes and drawdowns very quickly.
