Keyboard Bloom at /keyboard turned the whole keyboard into an instrument. Now there are three games built on it, all in the same scale, so nothing you press sounds wrong.
Keyboard Quartet (/keyboard-quartet) is for up to four people around one keyboard or one tablet. Each seat gets five keys: Coral on Q W E R T, Gold on Y U I O P, Sea on Z X C V B, Violet on N M , . /. One seat plays a short phrase and everyone else echoes it on their own keys. A clean echo grows the table's garden. There's no timer and nobody gets knocked out.
Bloom Rush (/keyboard-rush) is the easy one. One key glows in the same spot for every seat. Mash it to grow your flower, and every hit climbs a scale, so mashing sounds like a run. Twice a game the sun comes out and every key counts while the whole table fills one meter together.
Keyboard Garden (/keyboard-garden) is for one player. Flowers sprout on random keys across the board: pick them in full bloom for 3 points, before they wilt. Your streak turns into a melody, golden sunflowers want a quick mash and give a heart back, and three wilts ends the run. Everyone gets the same garden each day, and there's a daily top-ten board.
Invites and challenges have their own link cards. Save a friend a seat and the preview lights it up. Send a score and the preview asks whether they can beat it.
