Stack the Clues, Step by Step This is not just a simple sorting game. It's a dual challenge for your brain and your step count. How to Play? Tiles are scattered at the bottom of the screen, with a temporary holding area in the middle. You need to move tiles into the main category zone first, then further sort other matching tiles into the correct subcategories โ€” tap on the tiles below and complete the sorting step by step. A variety of sorting methods await: image classification, jigsaw puzzle assembly, character splitting, text categorization... Every tile has its own hidden destination. There are also unrevealed tiles above that you need to tap to flip over. Each level has a limited number of moves. Clear and sort all tiles before running out of moves to win the level. Game Highlights *Two-tier sorting mechanism (main category + subcategory) โ€” more depth than standard sorting games *Multiple tile types mixed together: jigsaw, character splitting, images, text *Limited moves โ€” every step counts, with a tense but not overwhelming rhythm *Clean visuals, perfect for brain-teasing fun during short breaks Can you perfectly sort every clue within the move limit?
