Zen Garden Rules:

Each player begins the game with a Tea House and Tools tile.

The tile is placed using the same rules as a lantern tile. However, when you place it, you have a choice which side you want to place face up - Tea House or Tools.

A tea house is treated much like a lantern - it is wild, and it can still be a part of a pattern. However, it cannot be replaced like a lantern.

A tools tile can be replaced exactly like a lantern. However, it is a part of NO landscapes. It cannot be a part of any pattern.
