Follow the diamond along the track. The outlined zone is your target; the centre line of the spark decides the hit.

One spark. One well-timed touch. Find your rhythm in two forgiving minutes.
HOW TO PLAY / 01
A little spark. Your moment.
Press
Tap or click the game area, or focus it and press Enter or Space. One press stops the spark once. Holding a key never repeats.
Find your rhythm
Each hit earns 10 points. A miss breaks the streak but removes no points. Keep playing until two minutes of active time end.
Three small timing exercises
- Stop the spark inside a wide zone, without a clock.
- Try a narrower target at the same slower speed.
- Miss once, then hit the target on a later attempt. A miss is another chance.
Practice is 60% of the initial run speed, with its own state and no countdown. Open it from start, pause or result without changing a run or records.
Rules and scoring
A run lasts 120 active seconds. Hits earn 10 points, with no multiplier. Misses and expired attempts reset the streak without removing points. At 0/40/80 seconds, new attempts use 3/2.7/2.4 seconds per traversal and zones 28/24/20% wide. First move right, then alternate right and left, then repeat right, left and out-and-back. A target never moves during an attempt. Each result freezes for 400 ms, using active time. In out-and-back you have both passes to press.
Focus the large game button, then use Enter or Space. Touch or click anywhere in that button. Pause stops both movement and time; resume explicitly after interruptions. The centre of the spark counts, including the target boundary.
Only best score, best streak and completed practice are saved for Pulso rules v1 in this browser. No accounts, public ranking, ads or paid advantages. Reloading ends the active run.
About Pulso
What happens if I miss?
The streak returns to zero. Your points stay, and a new attempt follows after the short result display. Reaching the end without pressing also counts as a miss.
Can I play more slowly?
Yes, in untimed practice. Reduced motion removes decorative effects; timing the moving spark still requires visual and motor coordination.
What gets shared?
Points, hits, best streak and a common link. Nothing is posted automatically and your attempt sequence is not saved or replayable.

A tip to get started
Start with slower untimed practice to learn the movement. Use one tap or keypress per attempt and adjust your timing based on where the spark stops.
