In Helios, players are high priests in a distant world of the sun god AHAU, and the power of the sun drives everything in the game as players try to build temples, expand cities, and make their civilization flourish.

Development can succeed, though, only if you've secured a supply of the limited raw materials available, and the more that you've built of your temple, the more expensive the remaining parts will be. Glass manastones are the game's currency, and with them you can acquire people, increase the number of points you'll score, and more.
