Educational simulation: fun credits only, no real money. The observed edge wobbles over a short run, but converges to the exact house edge as the spins pile up. That convergence is the whole game.
European 2.70% single zero · house edge
vs
American 5.26% double zero · house edge
Same bets, same payouts, but the American wheel's extra 00 pocket nearly doubles the house edge on every bet. Where you place the chip changes the swings, not the edge.
