Ninjas bring rocks, scissors, and paper to a fight in Ninjan to help you recruit the strongest ninjas possible.

The deck consists of 48 cards, with cards belonging to one of three suits — rock/paper/scissor — and being valued from -6 to 10 (there are no Zero value cards).

Red for rock, green for paper, blue for scissors.

Each player is dealt a hand of nine cards. Place three random cards face up on the table in separate piles; these are your first targets. (The remaining cards are not used)

Each round, each player chooses a card from their hand, then reveal them simultaneously. Cards are then resolved one at a time, going from highest value to low. If 2 cards of the same number are played, the card that would "win" RPS will resolve first. For instance, if 4 Paper and 4 Scissors are both played, the 4 Scissors will resolve before the 4 Paper (but both will still resolve before a 3 Rock, because they have a higher number). If all 3 cards of the same number are played, Rock resolves first, then Scissors, and finally Paper.

To resolve each card, players see whether it can claim one of the piles in the center of the table. For example, if you play 8 Rock and at least one pile has a scissor card on top, you MUST claim one of those piles, even if you don't want to. Place all these claimed cards face up in front of you, then start a new pile with your 8 Rock. If you cannot claim a card, place your played card on a pile of your choice, leaving all numbers in the pile visible. Then resolve the next card this way until all are done.

After nine rounds, sum the values of the cards you've claimed. Whoever has the highest score wins.
