iStacked Rules

The game is played with 54 blocks; each block is 3 times as long and slightly smaller in height than its width.

The blocks are stacked in a tower formation; each story has three blocks placed adjacent to each other along their long side, and each story is placed perpendicular to the previous (so, for example, if the blocks in the first story are pointing north-south, the second story blocks will point east-west).

There are therefore 18 stories to the tower.
The object of the game is to successfully remove one block at a time without toppling the tower and placing the removed block on top of the tower.

The blocks can be placed however you like on top of the tower. This means, you can position your block in a way where your opponent will find it difficult to place his block in a stable manner when it is his turn.

Which ever player drops the tower loses the game.
