Teams search a 15 × 15 grid for diamonds with limited moves and incomplete information. Prioritise, test hypotheses, communicate — or dig in the wrong place.

Diamonds is an engaging, fast-paced team strategy game that focuses on important team processes: selecting and prioritising information, making decisions on insufficient data, communicating, and creating test scenarios to validate hypotheses.

Teams must choose their actions carefully to maximise their gain while searching a 15 by 15 tile area for diamonds. The live scoreboard shows every team's progress, so the room stays competitive to the last move.

A real session in 60 seconds: the control room, a team exploring and mining the map, information bought, and the twist that changes the last stage.
