REX is a streamlined chess-like digital board game that’s easy to learn and quick to play.
The board is a compact 5×5 squares, and each player starts with only 5 pieces: two “Guards”, two “Priests” and a “King”.
Each piece has different rules for moving — essentially, they’ve able to jump 1, 2 or 3 squares — and a built-in tutorial explains every point. Even if you forget, there are hotkeys to remind you which piece is which, and where it can move.
There are multiple playing modes, including computer opponents with four levels of AI, and an option to play against a friend.
The program is a bulky download, but that’s because it’s been developed with the Unity game engine, and you’re getting some very professional features.
