Solve a case of a stolen chair or ball or something else. You have witnesses with statements. When? Where? Who?
Find and connect a clues. Be the best detective.
Set up a location board. The board is modular so no two maps have to be the same. Players in a turn have 12 action points that they use to perform actions. Such as moving around, investigating the scene, questioning another detective and questioning a witness. Each action costs a certain number of action points. During setup, a solution is randomly selected according to the set locations.
Winner is the player who discovers the correct combination for the solution by announcing in her/his turn that have the solution and says it. But be careful, if you make a mistake, you are out of the game. Then player in secret look to see if it was right. If so, show everyone and win the game. If not, return the solution back and is out of the game.
