There's nothing wrong with this clean little JRPG (Japanese role-playing game), but there's nothing remarkable about it, either. It checks all the genre's boxes -- a world in peril, a group of unlikely young heroes, some flashy real-time combat, a touch of quirky humor -- but in the end, neither the world, the heroes, nor the story are particularly memorable.
What Tales of the Rays mostly has going for it is an open-handed approach to rewards and free play. Going on quests requires energy, but the app generally gives you enough to play for a good long while without buying any. On top of that, daily login gifts keep you flush with gald (in-game currency) and the gems you need to summon new heroes and weapons. The app's second strength is its animated mini-movies. These provide comic relief and move the (admittedly unoriginal) storyline along. The app offers little in the way of innovation or surprises, and Tales fans and JRPG veterans could get bored. New players though, and players who don't mind repetition and who enjoy tinkering with their skills, costumes, and weaponry could be in for hours of free entertainment. Bandai Namco hasn't reinvented the wheel here, but because of that, Tales of the Rays is a reliable, if unexciting, ride.
