This Imagine Logo project is similar to the old Logotron game XOR, released in 1987.

The object is to get to the next level by removing all the blocks. Each of the blocks is governed by gravity - they move down, but not up! Click on a block to move it. When two identical blocks touch, they delete each other. Use the Again button to reset a level if you become stuck.

Good Luck !
