Casino War is the simplest card battle there is: you and the dealer each get one card and the higher card wins even money. On a tie you choose — surrender and take half your bet back, or go to war by placing a raise equal to your original bet. Three cards burn, one more card each decides it: win the war and your raise pays 1:1 while your original bet pushes, and tying the war again pays a double-tie bonus. Provably fair, 97.94% RTP.
