If you're a fan of Tetris, you'll love Drop N Merge - an exciting and challenging game available for free on Greatmathgame.com. With basic math skills, your goal is to match blocks with identical numbers to merge them into a single block with the next highest number. Avoid filling up a vertical line by strategically dropping blocks to make them merge. Create chain reactions by dropping consecutive numbers to eliminate multiple blocks at once. Be careful not to drop a block when no space is available, as this will result in the end of the game. Enjoy the game by using your mouse to control the blocks.
