Required: 100M Or So.
Guide: If you haven't heard of the term "Doubling" it is a good way to win when you dice. Let's say you bet 1m, if you lose then you bet 2m, and so forth. The only way to lose if you have 100M is if you are on a 7+ losing streak, which will never happen.
Example:
1m - lose
2m - lose
4m - lose
8m - lose
16m - win.
Lost - 31m
Won - 32m
Of course you only win 1m every time, but if you do it alot you can get a nice profit.
