This is a strategy that I created where you place a bet on one number only for however many spins you choose. It isn't a very good short-term strategy (obviously) but could yield big rewards over, say, a hundred spins. It only requires your chosen number to land 3 times out of 100 to make a profit. If it landed disproportionately more then your profits could be huge. Your number isn't guaranteed to come out, of course, so you may lose each spin.
This program simulated roulette using random integer generation and can perform any amount of spins, across any amount of loops. User can input bet size, starting balance and which number to bet on. Graphs displayed at the end are stem graph of which numbers came out, balance after each spin (only shows last loop) and end balance of all loops.
