Stackability

Has the tagline "The funnest stacking game ever".

From the back of the box:

A great action packed game! Stack pieces 1 or 2 at a time, or by color!

Players race against the clock trying to stack unique pieces because nobody knows when Stackability will pop and shoot the pieces into the air.

Watch out! The direction of play can reverse on a roll of the die.

Don't let the stack pop or fall on your turn or you get a 'Stackability chip'.

Break a tie in an exciting "STACK OFF" challenge.

After five rounds, the best stacking player wins.

The game has a battery operated base that you prime by pushing down. When the music ends the base is activated and launches the pieces into the air.
