Ninjan

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

Each player starts with a hand of nine cards, with cards belonging to one of three suits — rock/paper/scissor — and being valued from -6 to 10. Place three random cards face up on the table in separate piles; these are your first targets.

Each turn, each player chooses a card from their hand, then reveals them simultaneously. Going from high value to low, breaking ties according to the RPS rule, players see whether they will claim one of the piles in the center of the table. If you play 8 rock, for example, you must claim one of the piles with a scissor card on top, placing these claimed cards face up in front of you, then starting a new pile with your 8 rock. If you cannot claim a card, place your played card on a pile, leaving all numbers in the pile visible.

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