Hear a sound.
Build it.

eski is a daily sound design game. Each puzzle plays you a synth patch. Its blocks are already on the board: set their controls until your sound matches, and every guess marks each control green, yellow or red.

1

Listen

The Target block plays the sound to match and the Output block plays yours. Shift+Space and Space switch between them without losing your place.

2

Set

The target's oscillators, filter, envelopes and effects are already on the board. Shape their controls until it sounds right.

3

Check

Submit a guess. Green is right, yellow is close (the greener, the closer) and red is something the target leaves alone. Greens lock in.

Four difficulties

Earn XP for every patch you solve and work up through four difficulties, from three-step sliders to the finest settings.

A new patch every day

Easy, Medium and Hard each get a daily patch. Keep your streak going, earn XP for every solve and work up through four difficulties, from three-step sliders to the finest settings.

Learn synthesis

Ten hands-on steps from one oscillator to a full patch. Each step sets up a board for you, so there's only one or two blocks to add or settings to change. Play with them, then match the target. Hints are there if you want them.
