Vertex Shifter Walkthrough Cool Math Games
A game where you need to place blocks in the right places. You can move the blocks in any order, you can select them by pressing the space bar. Each movement of the block decreases the number drawn on it. If the number is 0, then it cannot move on its own, but another block can move it. Also on the playing field there are special icons that can move blocks until they hit a wall or other block. The game is taken from the site Cool Math Games.
