skyjo action

New version of Skyjo that adds action cards and wild cards.
In Skyjo, each player has 12 cards in a 3x4 layout, two of them are visible, all others are hidden. On your turn, you can take the top card from the discard pile or draw from the pile. You can exchange a card (hidden or exposed) from your display with this one or discard the drawn card to turn a card face up.
If you line up 3 times the same number in a row or column, you can discard the cards. The round ends when a player has only open cards left. All cards will be revealed and points will be added for each player (cards are ranked from -2 to 12). The game ends when a player reaches 100 points or more. The one with the lowest score wins.
Action cards allow you to perform special moves:

Exchanging cards in your board
Trading cards between players
Steal an action card
Do two rounds in a row

You get an action card every time you put or reveal a wild card in your tableau, or you can take an action card instead of a normal move. Wild cards make it easier to collect sets and are very valuable sets in themselves (-10 or -15 points).
