Merge the blocks to grow the columns! Hold left-click on a block to pick it up, and move your mouse left and right to move the block. Release the block to drop it on a new column. Blocks that have the same number will add up together. Combine multiple blocks at the same time to multiply the points you earn.

Successfully merging blocks will fill up the bar on the left side of the screen. When that bar fills all the way, the columns will grow with more blocks to merge with!

Don't stack too many blocks... If the columns grow too tall, it's game over!
