A mini-game for World of Warcraft. It is inspired by a certain game where you stack different shaped blocks and try to remove lines by filling up all the spaces. Currently the game is unpolished but usable. To start the game, first go to the key bindings and set a key to GravBlox: Hide/Show. Then when bound, just click in the game frame to start. Controls: Arrow keys to move left/right, rotate and move down faster. Spacebar to drop immediately. Escape exits the keygrabbed state and pauses the game.
