Soccer betting combinations for accumulators I would like to bet on soccer games, on every possible combination. For example, I bet on $10$ different games, and each soccer game can go three ways: either a win, draw, or loss. 
How many combinations would I have to use in order to get a guaranteed win by betting $10$ matches with every combination possible?

If you bet on every possibility, in proportion to the respective odds, the market is priced so that you can only get back about 70% of your original stake no matter what.
