Fairly disappointed with this one

The game forces me to play black I like to play white. Very few or no pregame settings available. Can’t adjust any game settings before you play. It just starts to play. Slightly disappointed you can’t slide the pieces Instead of having the computer move them. I was hoping it would play like a real 3d board . That’s what I was hoping I would get with one of the more expensive games available.

Almost a 5

I have the iPad Pro 12.9. Would love it if the chess board was more centered and larger around. Please make this adjustment. Kinda annoying 🙈

Primus Chess

Great App. Beautiful. Many levels of play and AI tournaments are available. Good for beginners and intermediate players.
You can play in whatever mode suits your level of expertise and energy.

Most realistic-looking boards I've seen.

My most common disappointment with my many chess games is there always seems to be bad angle designs. Even with pivoting boards there never seems to be a satisfying angle. This game, however, is gorgeous! I haven't found a way to turn off legal moves yet. That is my only gripe so far with this game. Other than that, I absolutely love playing this! It feels just right!
