The central twist in the game play for Zooloretto XXL comes from a set of tiles representing other zoos valued at 4-6 points and additional coin, vending, animal and offspring tiles and tokens, all of which have a blue back to allow for easier separation of the bits at game's end. You mix these tiles with those from the basic Zooloretto game and play the game as normal.

When you have a full enclosure, you can take an action not available in the basic game, namely shipping all of the animals from that enclosure to another zoo for display there. Those animals are removed from the game, giving you room to grow again, and you take the topmost zoo tile from the stack, with the value of the tiles decreasing as the game goes on.

Zooloretto XXL also includes two trucks with only one and two holding pens for use in the two-player game and an expansion board and 22 new tiles for use in Aquaretto.
