Geometry Rash

Geometry Rash is a fast-paced HTML5 skill-based platformer where you guide a geometric shape through obstacle-packed levels. Jump, dodge, and time your moves perfectly to avoid deadly spikes and collect golden stars for rewards. Progress by mastering rhythmic jumps and unlocking new characters, all while competing for high scores in endless or level-based modes.

How to Play Geometry Rash

You start as a sensitive square navigating minimalist geometric landscapes filled with spiked triangles and moving platforms. Use mouse clicks, W key, or up arrow to jump over obstacles. The game features two modes: Endless Mode (compete globally for high scores) and Level Mode (progress through increasingly complex stages).

To survive, memorize obstacle patterns and time jumps to avoid “spiky triangles” and flat barriers. Collect golden stars to unlock new characters, such as neon cubes or glowing circles, which add visual flair but don’t alter gameplay mechanics.

Key Progression System

Unlock character skins and advance through levels by:

• Star Collection: Earn stars in Level Mode to unlock skins (e.g., “Glowing Cube” or “Neon Square”).
• Score Milestones: Reach specific scores in Endless Mode to unlock bonus stages.
• Level Completion: Finish stages to access harder challenges, like faster-moving obstacles or rotating platforms.

The Geometry Rash Legacy

Originally released in 2017 by indie developer tutbarao, Geometry Rash emerged as a staple in the HTML5 browser gaming scene, praised for its minimalist design and addictive gameplay. It popularized the “endless runner” subgenre within geometry-themed games, inspiring titles like Geometry Dash Scratch and Geometry Escape. Today, it remains free to play on browsers via platforms like CrazyGames, with unblocked versions available for school or workplace access.
