Quaterneo

Your goal is to rotate the cubes in the grid to make 2x2 squares of matching color cubes as quickly as possible! Move your mouse to hover over a 2x2 selection. Left click or press Z to rotate those cubes clockwise or right click and press X to rotate those cubes counter-clockwise. If the blocks reach the top of the grid, it's game over!

You can play in three different modes:

• Marathon: Clear 350 blocks to win the level
• Endless: Try to get the highest score before the game ends
• Survival: The game starts at level 20. You'll get points based on time and not matching. Try to stay alive for as long as possible!

HINT: Press Space to drop the next cube quickly. In marathon and endless, try to make chains of matching cubes for maximum points!
