About

Letter Stream

Features

Letters are flowing โ€” can you keep up? Letter Stream is a fast-paced word game where letters drift across the screen in glowing bubbles. Tap to catch them, arrange them in your tray, and spell a valid word before your speed bonus drains away. Every second counts. HOW IT WORKS Floating letter bubbles drift across the screen. Tap one to add it to your tray โ€” up to six letters at a time. Drag the letters around to rearrange them, then hit Submit when you've got a word. Complete 10 valid words to finish the round and see your final score. SCORE BIG, SCORE FAST Scoring is inspired by Scrabble letter values โ€” common letters are worth less, while rare letters like Q, Z, J, and X can score big. A well-timed six-letter word with high-value letters can be worth far more than a quick three-letter word. But speed matters too. A bonus bar starts at 100 points and drains every second from the moment you tap your first letter. Submit quickly and keep your bonus high โ€” or hold out for a longer, more valuable word and risk losing it. FEATURES - Satisfying letter-catching gameplay - Scrabble-inspired letter scoring - Speed bonus that rewards quick thinking - 6-letter tray with drag-to-rearrange - 10-word rounds with a final score screen - High score tracking - Haptic feedback throughout - Stunning dark visual design built for OLED screens Whether you squeeze in a quick round or chase a new personal best, Letter Stream is easy to pick up and hard to put down.
