ShakeDown

ShakeDown is a dexterity game for 2-6 players.
Your goal is to stack cards on top of a hand-held platform without them falling off.
Of course this is made a bit more difficult by the cards to be played being stored in the platform's base. So you have to move the base to get access to the cards.
All of the cards have point values which count against whomever causes them to drop.
Some of the cards also call for special actions (like "Do the twist for five seconds while holding the tower.")
And there the fun begins!
