There are no computer players in the game, so it must be played with other people. There are three levels of difficulty. The easy level results in all advantages coming up, the middle difficulty has some disadvantages with the advantages and robots can also get damaged (e.g. if it walks through the swamps or on the rocks). The difficult level has more disadvantages (such as no home), damages are more frequent and there are more options for robots (i.e. camouflaged color).
