The game is divided up into days. Each day, you can do various things such as visit the Slave Market, Tools Shop, Dungeons, Devil Cave, and the Warehouse. Your stats include the amount of Money you have, your Stamina, your level of Evil, and your current Level.

To make money, you buy slaves from the Slave Market, buy Potions from the Devil Cave, and apply those Potions to your slave. After waiting three in-game days, your slaves would have transformed into Weapons, of which selling them gives you a nice profit.

To beat the game, you need to beat the final dungeon – the Inferno in the Abyss.
