If Ego is winning easily, he becomes Watery. If losing easily, he becomes Fiery. Weak stones are marked with numbers. The higher the number, the stronger the stones. Hint - suggests places to play.
Higher numbers are better.
Unplay - takes back the most recent human move. If you click on the wrong intersection and you realize this while Ego is thinking, just click on Unplay and Ego will stop thinking and retract your move. If Ego has already replied to your move before you click on unplay, Ego will retract both your move and his response to your move and then respond after you play your new move. Unplay can also remove handicap stones. Clear - takes back all moves but handicap stones.
