The hold is much higher than the house advantages, just simply because every spin has a house advantages, and the buy in can be bet several times. If we can not see it make a experiment, buy in 100 and play, it will be much more than 100 in turn over before all is lost. If we flat bet one at the time it will last between 100 spins and infinity, but in most cases it will last maybe a few times 100 spins.
The AM wheel with a payout of 18/38 is very hard to beat, an wheel with 18/37 twice as food and a NOZ the best. The disadvantages looks small but are not. Statistical we can win anyhow, but less likely. A lotto win of a lot of money happens despite a disadvantage of about 50%.
