Rock Paper Scissors Ninja is a hidden-information strategy board game for iPhone — the schoolyard duel everybody already knows, played as a battle of armies in the same family as Stratego. Every rule below is exactly what ships in the game.
What kind of game is this?
Each side fields 12 weapon-carrying ninjas plus a stationary flag and a stationary trap. You see your own weapons; your opponent sees only identical soldiers. The goal: find and capture their flag before they find yours.
How does setup work?
- Your 14 pieces exactly fill your back two rows (7×2 squares).
- You place the flag and the trap yourself, anywhere in that zone.
- The 12 fighters are shuffled into the remaining squares — reshuffle as often as you like before starting.
- Online, setup runs on two 20-second timers: one to place flag and trap, a fresh one to shuffle and ready up.
How do pieces move and fight?
- One piece per turn, one square orthogonally (no diagonals), onto an empty square — or onto an enemy to attack.
- Combat reveals both weapons: rock breaks scissors, scissors cut paper, paper wraps rock. The loser is removed.
- Attacker wins → it advances into the square. Defender wins → it holds its ground.
- A piece that wins combat is permanently revealed — from then on your opponent sees exactly what it holds.
What happens on a tie?
Same weapon on both sides? Both players secretly pick again and the pieces clash a second time, repeating until someone wins. The winner keeps the weapon it won with — a tie is the one way a fighter can change its weapon mid-match.
How does the trap work?
Step on an enemy trap and your piece is destroyed instantly. The trap is never revealed and never consumed — it keeps catching attackers all match. Since flags and traps both never move, reading which motionless piece is which is the heart of the game.
How do you win?
Capture the enemy flag (immediate win) or eliminate every enemy piece. Bluffing matters: let them believe your scissors are a rock, park fighters as fake flags, and watch which of their pieces never moves.
