HyperRogue

HyperRogue is played on a hyperbolic plane, meaning space expands exponentially rather than following standard Euclidean geometry. This non-Euclidean design fundamentally changes movement and combat, as there are infinitely many parallel lines and you cannot easily circle around enemies.

The game was developed by Zeno Rogue and initially released in 2011. It is an open-source project that has received continuous updates and is available across multiple platforms, including PC and mobile.

While the game is strictly grounded in hyperbolic geometry, you do not need a math degree to play it. Players simply learn through gameplay that moving in a straight line changes their surroundings in unusual ways, making the grid feel practically infinite without wrapping around.

Because the game uses an infinite, wrap-free hyperbolic grid, returning to a previous location is mathematically impossible once you wander far enough. The massive nature of the hyperbolic plane ensures that exploration always feels boundless and distinct from standard tile-based games.
