This game is simple, the goal is to get one piece to level 4. Start by placing any number of pieces in any configuration beneath the red line. Press space to start the game then click on a piece to see it's moves, then click on the move to move it. You move a piece by jumping over a different piece horizontally or vertically, the piece you jumped is then removed. How far over the red line can you get?
This is based off a single player game I saw in a Vsauce video on YouTube.
