Double-zero roulette RTP

Double-zero roulette returns 94.7368% of total amount staked over the long run, giving a house edge of 2/38 (5.2632%).

How this figure is established

Fixed by the rules of the game. A wheel with 38 pockets and a 35-to-1 straight-up payout returns 36/38. The five-number bet covering 0, 00, 1, 2 and 3 is the one exception and returns 35/38, or 92.1053%.

The derivation

A double-zero wheel has 38 equally likely pockets: 0, 00 and 1 to 36. A straight-up bet wins with probability 1/38 and pays 35 to 1, returning 36 units. Expected return per unit staked = (1/38) x 36 = 36/38 = 0.947368, so RTP = 94.7368% and the house edge is 2/38 = 5.2632%. The exception is the five-number bet covering 0, 00, 1, 2 and 3: it wins with probability 5/38 and pays 6 to 1, returning 7 units, so its expected return is (5/38) x 7 = 35/38 = 0.921053, or 92.1053%. Adding a single pocket to the wheel nearly doubles the house edge, which is the whole of the difference between the two wheels.

This is arithmetic from the stated rules of the game, not a claim taken from an operator or copied from another site. You can check it yourself.

What this record cannot tell you

A long-run return says nothing about a session. Over a few dozen plays the outcome is dominated by variance, not by the edge. Why RTP does not describe your session.
