Free games like Diablo

Flare is a free, open-source action RPG in the tradition of the classic isometric dungeon crawlers, and the closest thing to Diablo on Gamidio. Click to walk and attack, fight skeletons, goblins and much stronger creatures through forests, caves, ruins and dungeons, pick up loot, learn powers and grow your hero in the Empyrean Campaign.

Shattered Pixel Dungeon is the turn-based side of the genre: pick a hero and descend through 26 randomly generated floors to find the Amulet of Yendor, with new levels, items and enemies every run. Red Rogue is a platformer roguelike where the rogue and her minion fight their way down through dungeon levels full of monsters, traps and treasure.

All three games are free and need no download. Flare and Red Rogue are best on a computer; Shattered Pixel Dungeon also plays well on a phone.
