MouseHunt is a passive game in which the player chooses a Weapon, Base, Charm, and Cheese to equip and then has the option to sound the horn every 15 minutes to go on a hunt. Hunts have several outcomes; Successful catch, Failure to catch, Pillage, or Failure to attract. In addition to this once every hour your trap automatically goes on a hunt and friends can take you on a hunt while your horn is available to be sounded. Mice that are caught give the player gold, points, and sometimes other types of loot that can then be used to craft or buy Cheese, Charms, Bases, or Weapons.

The game can be played on its website or mobile app as well as on Facebook. The game released on March 7th 2008 and has had continuous updates and events ever since. The game is developed by HitGrab and regularly hosts player feedback discussions with the head Developer or Lead artist in Friday Feedback Sessions.
