Unsigned Int

Put your brain to the test by combining numbers to give the target value. In the beginning, you'll add and subtract numbers. As time and levels progress, you'll also have the option to multiply and divide. As each hour goes by on the fast moving clock, a new set of blocks will drop onto the gameboard. Don't let the blocks reach the top.

Click on blocks to add to your equation. Once you make the target number the blocks will disappear and you will get a new target value to make. Be sure and click on the instructions to see how the operations work. Click on the Reset button to unselect any selected blocks. You can also click on a selected block to deselect it.
