How to Play TRIAD

Overview

Two players (Red & Blue) each deploy 18 hidden pieces on a 9×9 grid. The goal: capture the enemy Flag.

Pieces

Piece	Symbol	Range	Can Attack	Special
Scissors	3	3	Yes	Reveals if it moves 3
Paper	2	2	Yes	Destroys Bombs; reveals if it moves 2
Rock	1	1	No	Never revealed by movement
Spy	S	1	No	Proximity: kills Paper & Scissors
Bomb	B	1	No	Proximity: kills Rock & Scissors
Flag	♚	0	No	Immovable. Lose it = game over

Combat (Jump Attack)

Pieces that "Can Attack" (Scissors, Paper) can move into an enemy-occupied cell to initiate combat. Both pieces reveal simultaneously.

• Rock (1) beats Scissors (3)
• Scissors (3) beats Paper (2)
• Paper (2) beats Rock (1)
• Same type = both destroyed (mutual kill)
• Attacking a Spy = attacker wins (Spy can't fight back)
• Paper attacking Bomb = Paper wins (sapper defuses)
• Scissors attacking Bomb = both destroyed (explosion)

Proximity Hazards

After any move or drop, check adjacency (up/down/left/right):

• Spy adjacent to enemy Paper or Scissors → destroys them
• Bomb adjacent to enemy Rock or Scissors → destroys them
• Paper adjacent to enemy Bomb → destroys the Bomb (sapper)

Revealing

Pieces start face-down. They permanently reveal when:

• They move their full range (Scissors moving 3, Paper moving 2)
• They participate in combat
• A proximity hazard triggers on them
• They are dropped from hand (always face-up)

Rock, Spy, and Bomb all move 1 space and look identical to the opponent — the Shell Game.

Drops (Shogi Rule)

Captured pieces join your hand. On your turn, instead of moving, you can drop a hand piece onto any empty cell adjacent to one of your own pieces. Dropped pieces are always face-up.

Winning

Capture the enemy Flag to win. Only Scissors and Paper can attack the Flag directly.
