Summoners collect and train hundreds of mythical creatures, each with unique skills and elemental affinities. The roster draws from diverse folklore—gods, demons, and legendary beasts—all rendered in detailed anime-style card art. Regular crossovers with famous anime series and weekly events keep the lineup feeling fresh.

Core gameplay revolves around a six-by-six Runestone board. You drag gems to match three or more of the same color, triggering attacks from your team. Different gem attributes power up different monster types. Mastering combos, team synergy, and boss mechanics is what separates casual players from serious veterans clearing a thousand-plus stages.

Tower of Saviors is a mobile puzzle RPG that blends gem-matching with monster collection. Built around a fantasy conflict between gods, demons, and humans fighting over the legendary Enochian Tower, the game pulls its characters from Greek, Chinese, Egyptian, and other mythologies. It's completely free and wildly popular across Asia.
