Description

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.

We've included a mate puzzle generator to create an almost infinite variety of checkmate puzzles that allow you to sharpen your chess instincts, and multiplayer modes that allow you to use your device as a virtual chessboard, or play via bluetooth or wireless with a local opponent.

We've also added a "Time Control" mode, to allow you to play using standard chess time controls, rather than a predefined difficulty level.

Features include:

- Mate puzzle generator - an almost infinite number of puzzles.
- Two player mode over Bluetooth / Lan.
- Tabletop mode so you can use your device as a virtual chessboard.
- Various different boards, pieces and graphical options.
- Support for all skill levels from total novice to expert.
- Supports all orientations, so you can make full use of your iPad Smart Case or stand.
- Supports multitasking, so you can follow along with videos/ebooks.
- Focus mode, to hide the UI so you can focus on the board.
- Puzzles and practice levels, so you can practice your endgames or play some interesting challenge levels.
- Mini-tournament mode - a six-game mini tournament mode for the more serious player.
- Elo rating estimation from your game results.

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!

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.

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 🙈
