Do some cool math to clear out blocks! Click on numbers that add up to the number shown at the top of the grid. The numbers don't need to be adjacent to each other. Make sure the numbers don't reach the top of the grid or the game will end. Select one of three modes to play:

• Classic Mode: Each time you add up to the target number, a new row is added to the bottom of the grid.
• Time Mode: Add up to the target number before the timer runs out. If the timer runs out, a new row is added and you don't get any points.
• Levels Mode: Complete a series of challenging levels by adding up to the target numbers. Each match you make will fill up a bar at the bottom right of your screen. Each time you completely fill up the bar, you'll go to the next level.
