Master the rules of color as you merge, slide, and strategize your way through each puzzle.
Build, test, and share your own challenges with the in-game level editor.
Challenge your logic in this casual, minimalist puzzle game. Slide and merge colored blocks using the additive color system — combine red with blue to create magenta, green with blue for cyan, and red with green for yellow. Clear clusters of connected colors, but think strategically: merging the wrong way might leave you stuck.
Solve increasingly complex puzzles filled with special blocks:
Prisms to convert white blocks into essential red, green and blue blocks
Duplicators to copy blocks
Gates that restrict movement
Void holes that delete blocks
and more...
Your goal? Fill all outputs with required blocks and clear connected blocks to conquer each level.
