To play the game, use your mouse to click on the screen to drop a block. You can also right-click to rotate the block. Your goal is to connect three blocks of the same color and fuse them together. When you fuse blocks together, they will transform into a new color that is worth more points. Keep fusing blocks together to climb the color chain and set a new high score. As a tip, remember that when you fuse blocks together, the new block will always appear in the bottom-left space of your chain. Use this information to plan ahead and create more combo opportunities. Click on the screen to drop blocks and right-click to rotate them as you work to fuse blocks of the same color and climb the color chain.
