Rhythm recall

How to play

1. Wait through four count-in ticks, then listen for the drum hits. Every numbered position represents an equal amount of time, including silent rests.
2. Select the positions where a drum hit played. Select a filled position again to remove it. With a keyboard, use arrows to move and Space or Enter to toggle. You choose a pattern; you do not have to tap in time.
3. Submit your pattern when it is ready. Review the original and your answer: a circle marks a missed hit and a cross marks an extra selection.
4. Partial matches earn points. Matched hits add credit, extra selections reduce it, and an exact pattern earns 100 points.

Try an example

Count the eight positions in the example and notice the spaces between drum hits.

Scoring and modes

Each round is worth up to 100 points. The score counts matched hits, subtracts extra selections, then divides by the number of actual hits. It never drops below zero. A fully correct round requires every hit and rest to match.

Daily and practice have ten rounds, worth up to 1,000 points. Pattern lengths grow from four positions to eight, twelve and sixteen. Daily gives everyone the same patterns for that UTC date; practice starts a fresh set. Neither has an answer timer.

Head-to-head gives both players the same patterns and clock. You cannot pause or replay. The higher point total wins; total response time breaks tied scores. Answers reveal when both players submit or the round expires. Ranked results affect your Rhythm recall rating.

Practice saves your current attempt. Start a new practice puzzle when you want a fresh one. Practice results do not change Elo.
