Gyromancer is a puzzle RPG developed by PopCap Games in collaboration with Square Enix and published by Square Enix. It combines the role-playing elements and artwork of Square Enix games with the tile-sliding game play of one of the titles in PopCap Games' popular Bejeweled series, Bejeweled Twist. It has been compared to another puzzle RPG, Puzzle Quest: Challenge of the Warlords.
While the game has no relation to the Final Fantasy series, it incorporates several staples from it. Monster share the names of many recurring enemies from the Final Fantasy series, such as the Cait Sith. Many spells share their names, like Flare, and Remedies also make an appearance. The main currency is gil.
Players assume the role of Rivel, a summoner who ventures through the enchanted Aldemona Wood. Each stage contains its own objectives, from defeating beasts that block the player’s way, to solving puzzles before time runs out. The player learns to summon many of the beasts he encounters, using them in battle. There are over 50 monsters to be summoned. Matching gems fills your monster's action gauges, while the opponent's action gauges fill over time, according to your level compared to your opponent's.
Matching gems that are the same color as your chosen monster fills its action gauges much faster, as well as doing matches and combos. Matching gems that are the same color as your opponent's prevents their action gauges from filling. Most of the time, once an action gauge is filled, one of the gems on the play-field is changed to an ability gem, which deals damage and other effects according to the ability, if matched. Each stage has awards for fulfilling various accomplishments.
