Monster Strike

Monster Strike (モンスターストライク Monsutā Sutoraiku) is a mobile physics game with elements of RPGs, strategy games and cooperative multiplayer. It is developed by Mixi for the iOS and Android platforms. The game was co-created by Yoshiki Okamoto. In Japan, its name is often shortened to MonSt (モンスト Monsuto). By June 30, 2015, the game had daily revenues of $4.2 million, and later became the highest-grossing mobile game of 2016, earning $1.3 billion for the year.
A more traditional RPG of Monster Strike was released for the Nintendo 3DS in December 2015.

The game can be summed up as a cross between Nintendo's Pokémon and Rovio's Angry Birds; the former in that it centers around monster collecting and the latter in that battles take place using catapult mechanics, similar to an earlier Capcom title called Metal Walker.
