In 2006, mobile developer GungHo spun off its popular mobile gem-matching game Puzzle & Dragons into an anime series, Puzzle & Dragons X. The show ran for 89 episodes and spawned a pair of Japan-only 3DS games, Puzzle & Dragons X: Gods Chapter and Dragons Chapter.
Puzzle & Dragons Gold, released this week for the Nintendo Switch, is those games with a shiny new coat of paint.
Puzzle & Dragons Gold has the gem matching, but instead of random creatures, players battle against each other.
The mobile version of Puzzle & Dragons is a gem-matching gacha game.
