Diabelski Krąg is a tactical game in which (in it's basic version) two players compete to either defend or kill a infantile princess of a fantasy kingdom untill the dawn for 3 nights (time is randomly simulated after each turn). The "good side" are four powerful mages, while the "evil side" are eight demons. Though tactical, the game is pretty random, since the demons change their statistics every turn due to the changing phases of the moon and stars. Demons can change their status, there are 8 stages of it, from 100% material (they can be hurt and they can fight) to 100% spiritual (they can fight only using psychic attack, but can pass through the walls, etc.). Demons can use fireplaces to move, cast a curse, use pentagrams and holes to hell. Mages can use garlick, Torch of Ithilien's Temple, Ilih's Weed, wand, salt, Magic Book, Elvish Drop, pray and exorcise. One of the last games by Sfera.
