This site checkers game is designed poorly, the programers didn't take into account that iPhone users have a swipe to go back and forth, 1. Imagine playing a 1 min game and you keep losing on time because each time one moves a checker piece, the screen reverts back back and forth. 2. I have tried to disable it, no matter how much code I write to help delay the time between swipes, this site is just not designed poorly for playing checkers and I keep losing. Fix your ui, no more swipes! Imagine playing a bot and you are losing on time. Its just not fun anymore.
