Your goal is to capture as many souls. It all starts with the fact that you distribute sin (click on the channel sinners), then start to drop souls of people who in life were affected by your sin. As soon as the soul will fall - it will be yours.
The accumulation of a certain number of souls you can spend them in the acquisition of Hell beings that spread sin without your help. Unfortunately, your servants are not so endowed with wisdom as you, so soon attract the attention of the people and representatives of Paradise, resulting in increased probability of their exile. In the exile the creature slowly falling channel sinners. It is worth noting that in the channel sinners at a time can fit only a limited number of souls and beings.
With the ever increasing flow shower soon begins overflow channel sinners, in this case, those souls that did not fit into the channel, will be lost to you, so you need to stock up a means of delivery of a large number of souls (bags, boxes, and so on).
After accumulation of a sufficiently large number of souls you will be available to purchase buildings. Buildings are also spread sin, and significantly better than the creatures, but their effectiveness depends on the number of beings who act as intermediaries between people and buildings Hell (the effectiveness of Grekhovodov depends on the number of tempters, the effectiveness of the Spheres of evil on the number of devils, and so on). As buildings allow you to accumulate experience of creatures. The experience allows you to develop skills in a specific area. It is worth considering the fact that the increase of skill in one area necessarily has a negative effect in another (improving income increases the likelihood of expulsion).
Hell periodically supports throwing various bonuses, the frequency of emission of the bonuses in the future, it is possible to increase the skills of buildings, which can increase the accumulation of a certain amount of experience after the construction of the Generator of the Apocalypse. The revenue generator Apocalypse depends on the size of your army of creatures.
