Guide a red square through compact grid-based puzzles filled with sliding blocks and locked paths. Clear the way, collect every yellow key, unlock the yellow door, and reach the exit to win. Simple rules, clever layouts, and satisfying logic challenges make each level a fun brain teaser.

Drag with your mouse or finger to slide blocks and move the red square across the grid. Plan each move carefully to open paths and reach all yellow keys. Once every key is collected, the yellow door unlocks—slide through it to complete the level.
