Players can select from multiple difficulty levels to match their skill. Level 1 is beginner-friendly, allowing novices to enjoy wins, while Level 2 suits players with some experience. From Level 3 onward, the computer becomes a formidable opponent, challenging even club-level players. The score displayed reflects the position from White's perspective, providing clear feedback during play.

Fancy something different? When starting a new game you can also choose Chess960 (Fischer Random). The starting position is drawn at random from 960 possible setups, or you pick one of them by its number. Memorized openings won't help here, pure chess understanding decides the game. There is also a custom position variant with a built-in board editor, ideal for practicing endgames or playing out a specific position against the computer.
