Control gravity and negotiate your way through a series of increasingly difficult puzzles!
In Slam, you control only one thing - gravity. All you have to do is get the glowing energy crate to the goal - simple enough, until we throw in barrels, sliders, switches, magnets, teleporters and a whole host of other mechanics that turn difficult puzzles into near-impossible ones.
Use your keyboard or controller to try and solve levels - and once you've solved them, try the tougher challenge of solving them in the smallest number of moves.
