Special rules
ZWOO offers a unique set of special rules, these are currently:
Add draw amounts
On top of a draw card, further draw cards can be placed. The number of cards to be drawn is added. You can put +2 cards on top of +4 cards, as well as +4 cards on top of +2 cards.
This rule guarantees fun games with your maybe-soon-to-be ex-friends. The twist of this rule is, that draw cards like +2 or wild +4 can be placed on top of each other, allowing the amount of cards to be drawn to skyrocket. Though, it should be used carefully since there is a large possibility that the friend who had to draw the tremendous amount of cards might not stick along any longer.
Tip
The current amount of cards to draw will be displayed on top of the pile.
Deck-swap
When a player lays a 2, he can choose any player with whom to exchange all cards.
Are you ready for a game that turns 180 degrees in the last second? This rule is right for you. Your friend is nearly finished, but you still have your deck completely full? Just place a 2 and swap your decks. Any 2 will be truly mighty, but be careful, you can literally gift someone your win when you are not paying attention.
Tip
It can be hard to keep track of the state of the game with this rule enabled. It's recommended to enable feedback messages to increase clarity and reduce confusion.
