Devil’s Number by Red Tiger Gaming is a high-volatility slot with a gothic theme and a 5-reel layout. The game uses 30 paylines, a 95.05% RTP and stakes from 0.2 to 40. Its symbols include standard card values, skulls, a flaming vessel and a dark book motif, all set against a haunted library backdrop.
The main feature is the Mark of the Beast, which can upgrade high-paying symbols during a win or remove low-paying ones before triggering cascading tiles. This mechanic is designed to change the value of a spin while the reels continue to settle. A paytable is available in the demo version, which lets players review symbol values and practice before playing for real money.
Free spins are triggered by three scatter symbols on the middle reels, awarding 12 bonus rounds. During the bonus game, upgraded symbols remain in play for the rest of the feature, while low-paying wins can be removed and cascade. The demo version allows players to play for free and study the slot structure before staking real money.
