DERIVED — check the arithmetic yourself

A real European wheel has a house edge of exactly 1/37 = 2.70%.

37 pockets, 0 to 36. Every bet on the table pays as if there were 36.
Red: 18 winning pockets x 2 / 37 = 97.30% returned
Black: 18 winning pockets x 2 / 37 = 97.30% returned
Even: 18 winning pockets x 2 / 37 = 97.30% returned
Every bet returns 36/37 = 97.30%. The edge is the single zero and nothing else.
Checked against all 10 bets in this game's own table. Identical.
An American wheel adds a second zero: 36/38, a 5.26% edge. That is the whole difference.

This game is a European wheel, so our published figure and the real-world one are the same number.

No unsourced real-casino figure appears anywhere in this section. Where an edge follows from the rules it is derived and shown; where it does not, it is left out and the reason given.
