I made a play on a zero-wheel, which return all outside bets if zero hits, and pays 37 on a straight. I then put three 0.1 chips on the two dozen, but as split pays as usually, but straight up 37, the bets inside were 0.05 on four numbers, the same as the splits 14,17,20,23.

The loss is still 0.8 on the eight numbers, but just 0.2 on zero and the payout for the doz is the same, but 1.05 on the numbers.

Took 200 spins to climb up to 10.05.
