Diabolik - Heists and Investigations is a hidden movement game for 2 to 4 players divided into 2 teams, where the players play as Diabolik and Eva (the Criminals) against Ginko and Morrigan (the Detectives). This game is inspired by a famous Italian comic series, where this robber couple designs and executes heists, using disguise and latex masks to complete these daring thefts.

It's a "cops and robbers"- style game, where Diabolik and Eva move in the shadows of the state of Clerville, unseen by their adversaries, until the Criminals are identified by the Police; then it becomes an open chase, where the criminals will be forced to flee on the main board, visible to all cops. Finally, the game becomes a puzzle, when it comes time to complete the actual heists and investigations, with the two factions trying to achieve their respective goals.

The Criminals will have to complete two heists out of the three available to win the game and to do so they will have to move, hidden in the shadows, leaving traces of their path to the Police. The Police will have to investigate the traces left by criminals, but they are not alone: they can call for four Police Officers to help, to keep every corner of the country under observation.
