Field is created by all cards.
And cards are overlapped randomly.
First, players have some counter chip.

Be careful, you can get only top most cards.
Finally, most highest score player is the winner.
There are some types of cards.
"Idol", "Manager", "Otaku".
If you have "Manager", you can get additional score.
But if you have same colored "Manager" and "Idol", the Idol loves the Manager and leaves your hand.

But if you don't have same colored "Idol", the Otaku acts violently, and decreases your score.
You should control number of your counters, and choose what card you take.
