The game is played like Forest Shuffle, but the following rules may differ from what you already know from Forest Shuffle and its expansions.

Starting Caves:

5 Starting Caves are drafted at the beginning of the game, after you've drawn 6 cards to hand, but before the game starts.

Caves are drawn in counterclockwise order.

After everyone has chosen a cave, they perform their effects in counterclockwise order.

Then the game begins.

Bogs:

When a bog is played, place a card from the stack into the bog.

Bogs have 4 card slots: 2 at the top and 2 at the bottom. They don't have slots to their left and right. Therefore, cards that are split left and right can never be played into a bog!

They either have permanent effects, or they're worth points at the end of the game.

The back of every card in play shows a universal bog, which you can play just like any other card. Like a bog, they have two card slots at the top and bottom.

Some card effects allow you to place a card as a bog: Just take the card and place it face down in your forest.

Some cards can only be placed in a bog.

New Icons:

There are 6 new tree icons.

There's a new species icon because we've introduced mice as a new species to the game.
