The table above presents number of combinations for the system given. There is also cost of the system for single stake, if you are playing with double stake than you multiply system`s value by x2, triple stake multiply by x3 etc.
How to play with the system, we will discus it on an example of the system 3/4. You have to choose 4 matches from the offer (A, B, C, D) from which 3 have to be typed correctly and 1 can be typed incorrectly. In this system matches occur in four triple combinations: A, B, C/A, B, D/B, C, D/A, C, D. The cost of such system is 4 for single stake, 8 for double stake and so on. To this system you can add so called "dead cert". It`s a match, which result you are 100% sure. Placing a dead cert makes the rates go up, but this match have to "walk in" necessarily so that the bet will be won.
If for e.g. you will choose 5/7 system, you type 7 matches form which 5 have to be bet on correctly. In such system there will be 21 combinations with 5 matches. Systems form 2/13 to 12/13 are available only at bat-at-win.
