Ah just I was getting my head around the sums involved here you go and throw a spanner in the works 
I don't think that's quite correct. That user will be auto-cashed out at 1.67x or what ever, but not the game itself. The game itself has a separate higher limit. Hence for the game limit to be hit, you generally require >= 2 whales playing at once (or it happens at a very high bust point).
And ideally, the per-game limit never gets triggered, because it's rather shitty for players that their bets are affected by other players action (even though it doesn't change the EV, it still sucks)
If only a single person made a bet, and if they made a max bet, the game would auto-cashout before reaching 1.67x.
