It is the battle of Cards-Knights. Each Knight has its suit and value, the higher value covers the lower of the same suit - Cards-Tricks rules. You are commanding your 6 knights to move and kill opponents Knights(of lower value and sames suit). But Opponnet's Knights also move to kill your Cards-Knights. So, a bit of strategical planning. Make your troops (even if lower forces-values) to overcome opponents. Prove, your strategy may win! Of course with sexy reward for the winner!
