It's Mine is a two-player card strategy game in which each player recruits a gang of thieves, then plans how to control popular locations and sites (called "districts") in Rome, London, Paris and Barcelona. These gangs are commanded by major crooks (boss cards), each of which can have an additional number of secondary burglars (action cards). The more criminals that a player places in a particular district, the more influence they obtain there, so the more likely they are to earn the valuable reward awarded by the district. In addition, players can also collect sets of art pieces that will provide extra victory points at the end of the game. In the end, the player whose gang scores the most victory points wins.

It's Mine is a gamers' game played in six rounds with a colorful and minimalist design that combines card drafting and set collection with area control mechanism. Players have challenging decisions such as commanding thugs, stealing precious works of art and burning evidences. Each city has its particular set of cards, so the game has a high replay value.
