Each block contains a slot for inserting a paper card with a task or dare. 

Players write their own challenges on the cards. 

During gameplay, participants take turns removing a block from the tower (excluding the top 2 layers) and performing the challenge written on it before placing the block on top. 

The player who causes the tower to collapse must draw three random blocks and complete all the tasks or dares. 

On the cards you can write truth\dares, turn it into a drinking game or do whatever you want.

Cut paper cards to about 20x69mm.

To insert them try bending them a bit along the long side and then flattening them after insertion.

To replace the cards just poke them through the back opening on the blocks.
