Frog Minutes is a puzzle video game for the iPhone, iPod Touch and iPad platforms. Designed as a tribute to the 2011 earthquake which ruptured Japan, it was released to Apple's App Store on March 30, 2011, with proceeds of the game's sales being contributed to Japan's relief fund. The game was directed by Tadayuki Nomaru and developed by Grasshopper Manufacture. Frog Minutes was first announced only two days before release, on March 28, 2011. Further details were then revealed through a press conference and charity event held in Tokyo, Japan on the day of launch.
Frog Minutes is a simple, open-ended experience where the player's only objective is to feed critters such as grasshoppers and flies to frogs, until their appetites are full enough that they can be caught. Frog Minutes contains a total of 10 frogs and five unique critters for them to eat; these 15 creatures have a dedicated "Field Guide" entry, which can be read to them by the narrator, who occasionally encourages the player during the hunt as well. Frog Minutes also challenges players to meet 50 different gameplay milestones; doing so completes a puzzle-styled picture of a frog, filled as these milestones are met, in addition to unlocking the game's sole Game Centre achievement.
A menu in Frog Minutes keeps a record of the frogs and critters captured by the player, their total play time, current and longest capture chain, and number of frogs failed to be captured.
