I have been using this strategy for a while. I call it the STEP STRATEGY:
You first choose 3 games with odds from 1.3 to 1.6 (not higher) and combine them into an accumulator, you use this system 3 steps and then you go back one step. After every step is done you should increase the money you bet by 25%.
Here is an example:
1.4x1.4x1.4 1st bet 10 units ~28 units
1.4x1.4x1.4 2nd bet 10 units ~28 units
1.4x1.4x1.4 3rd bet 10 units ~28 units
Total 84 units with 30 units stake, so this step ends with these three
and we advance to the 2nd step with raised money ...
If we lose 1 bet, we still have profit. If we lose 2 bets, no profit even.
As you see we follow 3 steps which include 3 bets.
Hope you like my strategy.
