A more human chess engine.
Primus is an entirely original, modern chess engine specifically designed for the intermediate player (up to 2000 Elo). It has been carefully tuned to play less like a machine and more like a human. At lower levels, it makes blunders of a straightforward kind that are easy to spot, but at higher levels more careful play is required to take advantage of more subtle tactical and even strategic errors. At its highest levels, Primus plays at around 2000 Elo, but even at the very highest levels, it still has occasional simulated lapses of concentration.
The engine was conceived out of frustration with the overwhelming tactical strength of modern chess engines. Most modern chess engines are so tactically strong that extremely careful defensive and anti-computer play is required to make any progress; in other words, it's nothing like playing a human. We wanted to create an engine that allows for a more human, strategic style of play where there's room to take advantage of the occasional blunder.

Ratings and Reviews
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!
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.
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.
