Demon

Demon by Play’n GO is a metal/occult themed video slot inspired by the English band Demon, featuring dark atmospheres, symbols such as runic engravings, demons, statues, crosses, and the singer Dave Hill as a premium icon on the reel. The game takes place on a classic grid of 5 reels and 3 rows with 30 fixed paylines. There are two special Wilds: the Wild Mask, which appears only on reel 3 and transforms all singer symbols into Wilds if it lands in the center; and the Wild Amulet, which appears only on reels 1 and 5. The scatter symbol is the Portal to Hell: if at least three appear anywhere on the reels in the base game, the One Helluva Night mode is activated, granting free spins. During One Helluva Night, between 6 and 11 free spins are awarded depending on the position of the Wild Mask on reel 3, and each free spin is assigned a random multiplier of x2, x3, x5, or x8 applied to wins. Within the free spins session, the Depths of Hell (“Hell Spins”) feature can be triggered: you need to re-trigger Wild Amulet on reels 1 and 5 during the free spins to gain additional spins, keeping the active multiplier, and if the Wild Mask also appears in the center of reel 3 at that moment, the multiplier is doubled. Demon does not offer a bonus buy feature or a gamble feature after wins. It is compatible with desktop and mobile devices, and the bet ranges from low to medium levels.

You can play it for real money.
