Catch letters, build words
Free · In‑App Purchases
Catch the falling letters, build your own words, and race the clock across 10 vivid worlds. Challenge any friend to the exact same round. Free to play!
Letters rain from the top of the screen. You decide what to spell.
Letterain is a colorful, fast, one-tap word game. Catch falling letters into your tray, build your own words, and race the clock through 10 beautifully themed rounds. Easy to learn in 30 seconds; with a mastery curve that runs deep.
HOW IT PLAYS
• Catch letters as they fall into your 7-letter tray
• Build any real word, 3 letters or longer
• Longer words and rare letters (Q · X · Z) score big
• Clear each round's threshold before time runs out to advance
• Cross a milestone and earn bonus seconds to extend your run
MORE THAN A GAME
Every 90-second round is a workout for your brain — sharpening critical
thinking, processing speed, and logic and pattern skills as you spot words
inside the chaos, under pressure.
