Beat Jump is a free browser-based rhythm platformer where you guide a glowing square through obstacle courses perfectly timed to procedurally generated chiptune music. With 5 levels spanning 100 to 180 BPM, the game tests both your platforming reflexes and your ability to feel and predict a musical beat.
Unlike traditional platformers, Beat Jump's obstacles — spikes, gaps, moving platforms, and gravity-flip zones — are placed at exact beat intervals. The music and the gameplay are one and the same: if you can hear the beat, you can navigate the level.
Press Spacebar, click, or tap anywhere to jump. Hold longer for a higher jump. Your character auto-runs from left to right — your only job is timing your jumps. On mobile, tap anywhere on the game screen.
Five levels of increasing speed: Level 1 at 100 BPM (cyan), Level 2 at 120 BPM (magenta), Level 3 at 140 BPM (yellow), Level 4 at 160 BPM (green), and Level 5 at 180 BPM (rainbow). Each level introduces new obstacle types and a new musical key.
Stars are awarded based on deaths: 0 deaths earns 3 stars, 1–3 deaths earns 2 stars, 4+ deaths earns 1 star. Checkpoints at every 25% of the level let you restart from the last checkpoint instead of the beginning.
A rhythm platformer combines traditional side-scrolling platform gameplay with music synchronization. Obstacles are placed at specific beat intervals, so timing your jumps to the music is the key to success. The genre became widely popular with games that put musical timing at the core of their challenge.
Rhythm games use BPM (beats per minute) to calculate exact timings. In Beat Jump, the Web Audio API generates music procedurally using oscillators and scheduled note sequences. Obstacles are placed at precise beat intervals calculated from the same BPM value, creating a tight sync between sound and visuals.
Beat Jump's Level 5 runs at 180 BPM — nearly three beats per second. At this speed the obstacles arrive so fast you need to anticipate the beat rather than react to visuals alone. Most players consider levels above 160 BPM to require expert-level rhythm sense. Master the lower levels first to build your musical intuition.
