Masked Rider Break Joker

Masked Rider Break Joker is a mobile collectible card game released by Bandai in Japan in August 2013, available on both Android and iOS platforms. The game centers on the long-running Kamen Rider (Masked Rider) tokusatsu franchise and uses a blackjack-style mechanic as its core gameplay loop: players build card hands whose values must reach or approach 21 without busting. Cards depicting Kamen Rider characters were obtainable through regular gameplay or via purchasable booster packs, which were priced between 200 and 315 yen and contained three cards each, with the first booster series launching on August 10, 2013. The service ran until March 31, 2016. As a smartphone-native CCG tied to a seasonal tokusatsu broadcast, it sits at the intersection of Bandai's mobile push and its long tradition of Rider merchandise. Documentation of gameplay depth beyond the blackjack framework is sparse, which is exactly why it sits in the uncharted archive.
