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.

More than a game

Fun that sharpens your mind.

Every round is a 90-second workout for your brain. Spotting words inside falling chaos — against the clock — trains the same skills that matter far beyond the screen.

🧠

Critical thinking

Every falling letter is a split-second decision. Grab the rare, high-value tile now, or hold your tray for a longer word? Letterain turns quick cost-benefit judgment into a reflex.

Processing speed

Read, recognize, react — over and over, faster and faster. Playing under a ticking clock trains your brain to take in information and act on it more quickly, even under pressure.

🧩

Logic & pattern skills

Rearrange seven letters into the highest-scoring play. Pattern recognition, planning ahead, and a growing vocabulary — the kind of mental muscles that compound the more you play.

Cheat sheet

Score big. Spell smart.

Your score for each word = letter values × length bonus × rarity bonus. Stack all three and the points explode. Here's the playbook.

💎 Rare letters = 2×

Any word containing Q, X, or Z doubles its score. Snatch those tiles whenever they fall.

📏 Length bonus

3–4 letters = ×1  ·  5–6 = ×1.5  ·  7+ = ×2. Longer words pay off fast.

🌧 Secret bonus

Spell RAIN for a hidden 3× LETTERAIN bonus. Keep experimenting — more may be hiding in the rain.
