# Engine test: cooperative outcomes (mode: cooperative, a shared win or loss for the whole team).

summary: >
  Test game for co-op outcomes. Two players must score 9 points together within 3 rounds. On each
  turn the current player rolls either safe (1 or 2) or risky (0, 0, 3 or 4). The best choice
  depends on the score so far, so a good agent must reason for the team, not for itself.

constants:
  TARGET: 9
  ROUNDS: 3
  SAFE: [1, 2]
  RISKY: [0, 0, 3, 4]
