Quick answer
Pulse is a free browser-based Simon-style memory game. A four-pad board plays a sequence of colored flashes with matching tones; you replay the sequence from memory by clicking, tapping, or pressing number keys 1-4. Each correct round adds one step to the sequence, and the playback speeds up. One wrong tap ends the run. Your longest surviving round is saved to local storage.
About the game
Pulse is a Simon-style memory game rebuilt with a neon glass aesthetic, WebAudio-synthesized tones, and a speed curve designed to escalate tension without becoming unfair. Every detail is procedural — no sound assets, no image assets — yet it feels like a polished toy you’d expect to pay for.
Tips
- Chunk the sequence. Your short-term memory handles 4 items comfortably and 7 with effort. Break the sequence into pairs or triplets mentally.
- Listen, don’t just watch. The tones are tuned to be distinct pitches — your ear remembers audio sequences better than your eye remembers spatial ones.
- Don’t rush. There’s no timer on your input phase. Take your time replaying the sequence.
Questions
How do I play Pulse? +
Watch the board flash a sequence of colored tones, then repeat it by clicking the pads in the same order. Each correct round the arcade adds one more step and plays the whole sequence back faster. One wrong tap ends the run. The top-left pad is also key 1, top-right is 2, bottom-left 3, bottom-right 4.
Does each pad have a different sound? +
Yes. Each of the four pads plays a distinct tone — 329, 415, 523, and 659 Hz — synthesized in real time via the WebAudio API. The tones rise slightly in pitch each round to add tension.
Is Pulse free? +
Yes. Pulse is 100% free to play with no sign-up, downloads, or ads during gameplay.
Does Pulse save my progress? +
Your longest surviving round is saved to your browser's local storage and persists between sessions.
