How it works

Four moves to master.
Then it's all skill.

Letterain mixes the timing of an arcade game with the depth of a word puzzle. The mechanic takes 30 seconds to learn. The mastery curve takes weeks.

1

Catch letters

Letters rain from the top. Tap one to drop it into your 7-letter tray. Miss and it's gone.

2

Build words

Tap tray letters to assemble any real word — 3 letters or longer. ENABLE + names + places.

3

Submit & score

Longer words and rare letters (Q · X · Z) score more. Spell RAIN for a 3× bonus.

4

Survive rounds

Clear the round's threshold before time runs out to advance. Bonus seconds for crossing the bar.

What you get

Designed to be impossible to put down.

Every system is built to keep the dopamine flowing — without overwhelming you with mechanics.
