Some systems involve betting on many numbers, perhaps In this case, you will 99.6 roulette gambling system quite often as you are covering more than half of the numbers.

But when one of the numbers does not turn up and it will almost half the time you lose all rouleyte the 20 bets you have made. This will often wipe out any wins to date.
