Bad review

This game is so slow and confusing to work. Doesnt give a clear explanation on what actually to do. (Not regarding how to play) it’s so slow even my grandma can run faster.
Pick up the pace guys. I dong recommend this app.

Ok but

Average game full of chess cheats maybe add a checker that people aren’t useing engines

Glitch

I just played a game where there was a glitch and opponent took my king off the board and the game continued….confusing and frustrating but also really hilarious. Love this app tho, this was a rare glitch

Bug

corrupted Game not repaired

Idiotic draw feature

The Game decides for itself to award draws or stalemates. It’s neither a draw or stalemate when the opponent can no longer move. That’s a loss!!!!!
