I guess you know how to play checkers.. Ok well this is just checkers AI engine same as chess AI, where you can do move and AI will do move for itself.
WARNING - Turbo Mode is VERY recommended! (its like 10x faster or more) This AI default depth is 4 (AI checks next possible move for itself, then your next move, its next move and your last move) You can change it by going into code and set calculation depth to 1 - 5. The bigger depth is, the better AI gets but needs more time to think.
