12 tiny daily pitch games for your ears, one puzzle each, the same for everyone.
Every day: 12 tiny pitch games, each with one numbered puzzle a day that is the same for everyone, from matching today's target tone in five tries to sorting, spotting and remembering. New puzzle: Once a day, likely at midnight like its sister site Huekle (the site does not state the time).
Hearkle is a free set of 12 small daily pitch games. Each game has one numbered puzzle a day, the same for every player, and you can share a spoiler-free result. There is no account and nothing leaves your device.
About Hearkle
Hearkle is a collection of short daily games that train how finely you perceive pitch. In the title game, Hearkle, you hear one target tone and move a pitch slider to match it by ear, with five tries and a closeness percentage after each. Each game gives one puzzle a day, numbered (puzzle 276 on 3 October 2026), and the same puzzle goes to everyone.
The other games come at the same skill from different sides. Hearddle asks you to spot the one off-pitch tone, Hearsort to sort tones from low to high, Hearmory to repeat a tone sequence and Heartween to find the pitch halfway between two. Others include a 30-second speed round, a higher-or-lower streak, Heardrift, where you hold a drifting pitch in a target band, and Heartonic, which asks you to name the scale degree over a drone. Hearfork estimates your just-noticeable difference, the smallest pitch gap you can hear, in cents; a lower score means sharper perception.
Every game has a Daily challenge and a Playground for practice, a short how-to-play with an example, and links to guides that explain the theory behind it. The site runs in many languages, needs no login or install and keeps everything on your device. The daily games and guides are free; an optional Personal Pass adds progress tracking, and there are tools for teachers. The same makers run sister sites for colour (Huekle), pitch (Hearkle) and rhythm (Chronkle).
