Congruence is a premium casual game developed by CSLE. It is a minimalist yet challenging puzzle game where the core mechanic gives you two pairs of pentominoes and asks you to combine each pair so that the resulting shapes share the exact same outline.

Think in 3D, solve in symmetry

The core mechanic of Congruence is simple. You get two pairs of pentominoes, which are shapes made of five squares. Put each pair together to create two shapes with the same outline. It sounds easy, but it can be challenging as you need to think in 3D and try different approaches to see how the pieces fit together.

For extra difficulty, there is an option to hide the outline until you discover it. This game features 513 distinct possible solutions, offering both depth and replayability. However, because the puzzles rely on shapes and logic, people who are new to them or have not tried them before can find them frustrating.

For players who love logic

Congruence tasks players with combining pentomino pairs to form matching silhouettes. With 513 solutions and optional hidden outlines, it offers both depth and replayability. While accessible in concept, its logic-driven design can be frustrating for newcomers, making it best suited for patient puzzle enthusiasts.
