Colored Blocks

Colored Blocks is a bright, addictive block-puzzle Chrome extension that combines relaxing strategy with fast-paced logic. Drag, rotate or swap blocks made of small squares onto a customizable grid. Complete rows, columns or 3x3 squares (Sudoku mode) to clear space and score points. Use the bomb power-up to clear areas, enjoy smooth animations, and rely on auto-save so you can resume anytime.

Multiple game modes and deep customization keep each session fresh: Classic, Sudoku, Colors (match 3+), Mastermind, Survival (rocks appear each turn), and Blocking Rocks. Choose grid size and shape, toggle Sudoku highlighting, and play with over 30 unique block types. Free to play and easy to learn but hard to master—perfect for quick casual sessions or long score-chasing runs.
