Gameplay
Pairs of various types of hats fall from the top of a 6 column playfield. The player can control the hats by moving them horizontally, swapping the positions of two hats, and dropping them downward. If one hat lands before the other, the player can continue to control the other single hat. The player must arrange the hats into stacks, and creating a stack of five of the same type of hat removes them from the playfield and earns points.
The player must take care to manage the height of the hat stacks; each type of hat is a different height, and particular nesting efficiency with each other type of hat. If the hats in any column crosses the limit line at the top of the playfield, the game is over.
