From initial tests the simulation feature appears to be working correctly. To make results more accurate, it will use part of the spins for analysis, and another part for actual testing. If the analysis isn't effective enough, you can expect the result to be a loss. From testing various spin profiles from player accounts, roughly 80% were profitable. The harder wheels were around a break even point which is what we'd expect. Anyway testing is a long way from complete, and later I'll create a video to show how it is used. But for now at least have a play with it and it is simple enough to understand how to use it.
