You can play 1 to 3 cards on your turn.
However, if you want to play a second or third card, you must flip a card that is already in play on table.
You can pass at any time after playing a card from your hand or turning over a card from the table.

When playing from your hand, you can choose to play as it is or flip it over. After each card played, the turn may end if one of the following conditions are met:

Error︰ If two cards on the table show the same color, your opponent wins the round.

Whoever wins the round takes all the cards in play.
The loser of the previous round begins the next round.
