Actually it's 2 hits in a row. If at anytime you get 2 hits in a row it will win. I used a single number as an example. Bet 1 unit on a single and win 36....parlay your winnings plus 1 unit, win 1332 units. So, if you get 2 hits in a row in 1332 spins you win....just betting 1 unit and parlaying

But, like you guys pointed out, it's not practical to play that many spins in a single session. I was just showing how powerful the parlay bet can be.

It's more practical to start off with more numbers. Let's say we're betting 1 unit on high/low, parlaying winnings. 2 consecutive hits wins 6 units. So as long as you can get 2 consecutive hits in 6 spins, you're in the money.

If you don't get the 2 hits in the first 6 spins, bet 1 unit on fewer numbers...maybe the dozen. 2 consecutive hits on a dozen pays out 12 units.

2 hits on a double street pays out 42 units

2 hits on a quad pays 90 units

2 hits on a street pays 156. Etc, etc

This is all based on 1 unit bets. We could say if we don't get a win on high/low in the first 6 spins, raise the base wager to 2 units...now, instead of betting dozens, stay on high/low. This would allow us to play high/low for 3 more spins...so all we need is 2 consecutive hits in 11 spins on an even chance bet.
