About

Keycap Puzzle

Features
Read full description

A block puzzle game made of keyboard keycaps! Drop soft, chunky keycaps onto the 8x8 board, complete a line, and blast — pop, it's gone. No timer, no lives. Take your time, play at your own pace, and chase a new high score in a relaxing block puzzle game. ■ Why you'll love Keycap Puzzle • Satisfying block puzzle: place keycaps on the 8x8 grid and complete rows or columns to clear them. If you like puzzle games, this one is for you. • The board glows as combos build: clear lines back to back and your score climbs fast while the board's edge brightens with the combo. • Offline game, no wifi needed: no internet, no problem. It works on the subway and on a plane. • Completely free: no in-app purchases. No coins, no chests, no gacha. Just the puzzle. ■ What makes Keycap Puzzle different • Special keycap blasts: build a combo and a Rare, Hero, or Legend keycap rides on a block. Clear the line it sits in and everything around it bursts in a diamond. The higher the grade, the wider the blast. • All-clear bonus: empty the whole board for a big score. The next all-clear comes a little harder, so you keep chasing it. • A real keycap collection: keycap art from the keyboard game "Ddalkkak" shows up at random. A bear, a panda, a fish-shaped pastry, a honey cookie — you never know what's next. • Light and smooth: a brain-training puzzle game that runs great on iPhone. ■ How to play • Drag the three blocks from the tray onto the board. • Fill a full row or column and it clears — score! • Place all three and three new blocks appear. • When none of the blocks fit anywhere, the game is over. ■ Tips for a high score • Think ahead about where the next block will go. • Clearing several lines at once is worth far more. • Don't break your combo. The longer it runs, the more special keycaps show up. • Keep a big open area on one side so a 3x3 is always welcome. Start Keycap Puzzle now! No timer, no "remove ads" purchase, and playable offline any time — a free block puzzle game.
