The blocks obtained by mining or stealing can either be used to load one’s own cannon and shoot at the opponent’s tower, where the size of the cannonball depends on the number of blocks you own. Alternatively, if you have three blocks, you can run to the your own tower and increase it’s height by one row.

Note, however, that a gold block is worth 50 points and a block of stone only 10. During the game, random items are spawned which can also be stolen from the opponent’s side and disappear after ten seconds, unless they have been picked up by a player.

The following four items are implemented in the game:

Speed

​​Increases the movement speed.

​​Golden Pickaxe

Increases the rate of mining of gold and stone.

​​Wall

Builds a wall in front of your own tower, lasting 10 seconds, that protects your tower from any enemy shot.

​​The Big Gold

Immediately gives the player three gold blocks.

A round lasts two and a half minutes and the player who has the more valuable tower, when the time ran out, wins the game.

The pulse’s properties depend on the angle and strength previously set by the player. Each tower is an array of box2D „Box“ objects. If the player extends his tower, all the blocks in the array are shifted up by the height of a single block in y-direction and the three blocks owned by the player are added to the array, forming the bottom row of the tower.
