Monster Strike (モンスターストライク, Monsutā Sutoraiku) is a mobile Japanese role-playing physics game with elements of puzzle, strategy and cooperative multiplayer.

The game can be summed up as a cross between Nintendo's Pokémon and Capcom's Metal Walker; the former in that it centers around monster collecting and the latter in that battles take place using catapult mechanics.

[vague] By October 2018, the game grossed over $7.2 billion worldwide, surpassing Puzzle & Dragons to become the highest-grossing mobile app of all time.

A second anime film, titled Monster Strike the Movie: Sora no Kanata, was released on October 5, 2018, in Japan.

A third anime film titled Monster Strike The Movie: Lucifer Zetsubō no Yoake was slated to be released in June 2020 but it has since been delayed due to the COVID-19 pandemic.

What sets it apart is that rather than being a tile-matching video game, the player aims and flicks their monsters around on a field, similar to billiards/pool,[5] bumping off of walls and enemies to perform damage.

Every turn, numerous counters on enemy monsters count down to launch various attacks that deal damage or add hazards to the field.

The final battle of each Quest Mission features a Boss monster that has a moving critical hit point.

A Tower of Champions event is also occasionally run in Japan, providing an increased challenge for players to win rare monsters and prizes.

There is also a Luck (ラック, Rakku) value, symbolized by a four-leaf clover, that determines the possibility of obtaining bonus prizes at the end of a Mission.

An additional Luck Skill was added to the game, allowing certain monsters to either have a critical hit or a shield to prevent damage on one turn.

Divination (獣神化, Jūshinka) is a combination of the two evolutions, giving the monster a second tier to their Strike Shot and a second slot for an Ableberry.

The Friend Hatcher is sometimes used for giving out rare Event monsters for collaborations, such as with Line Corporation and Weekly Shōnen Jump in Japan.

Collaborations have also been made with Lawson's convenience store chain, Monster Hunter Big Game Hunting Quest, Bakusō Kyōdai Let's & Go!
