A balancing/stacking dexterity game with a timing element.
Players take turns trying to stack little plastic barrels and planks onto a platform. The platform has a timer built in that is turned on at the beginning of each turn and switched off at the end of turn. The platform turns/wobbles. If barrels fall down, the active player has to stack all the barrels in other players' colours before he/she is allowed to use the off-switch. If the time runs out, the platform tilts, all barrels tumble down and the game is over. The player who has the fewest barrels left wins the game.
The level of difficulty can be adjusted with a switch. A solo variant exists in which the player tries to beat either a time record or how many barrels they manage to stack.
