WordPOP.

WordPop – Build words from falling letters and clear the board before it fills up. Letters fall from the top of the grid. While they’re falling, they’re locked and can’t be used. Once they land, tap them to spell words of three or more letters. Use the letter reserve to store a tile from the board and add it to your word when you’re ready. Tap POP to submit a word, clear tiles, and score points. Longer words clear more tiles. Clear the board with valid words before it fills up. Designed for ages 4 and up – simple rules, no account required, and family-friendly content.
