You play against an opponent.
Each player gets 7 cards.
The opponent's cards are on top left.
Your hand of 7 cards can be seen at the bottom.
Only you can see your own cards.
Initially, there is a colored card drawn and placed on the center right.
You start playing by selecting a card from your hand of 7 cards that matches the color or the figure of the colored card above.
Once you have selected your card to play with, drag and drop it on top of the colored card.
If you have a card with a star, you can select any color of your choice (green, red, blue or orange) from a drop-down list.
Next to the colored card, there is a pile of cards with green back (where only the top one can be seen).
From here you (and your opponent) draw a card when you don't have a matching card or a card with a star to play with.
If you don't have any matching card, click on the green card pile next to the left of the colored card to get a new card.
When you have more than 7 cards click on the arrow to traverse through your cards.
There are three rounds in total.
In order to win a round you need to get rid of all your cards before your opponent.
The winner of each round gets a bonus of 50 points.
Each time you have a valid card to play with you get 10 points.
Each time you need to pick a card from the green pile, you get a penalty of 10 points.
The winner of the game, after the three rounds, is the one with the highest score.
