Question. On the online gambling sites, can you just double up your bid on red/black for roulette? Easy money that way.
That is called the Martingale System. It works fine as long as:
- The house has no max bet
- You have an almost infinite amount of money
Consecutive streaks of the same thing do happen and they happen a lot.
Consider if you had 10 reds in a row, but you were betting black and started with a £1 bet. By that 10th spin you'd be betting £512. That's £512 to get your initial £1 (and subsequent losses) back.
The record run is something like 30 spins of the same thing. Would you have the required £536,870,912 to make the wager on the 30th bet?
