Devil's Sevens

About this Slot

Devil's Sevens is a horror-themed slot from Olimp with an RTP of 96.5%, high volatility and a maximum win of 25,000x. The game uses a 6x5 grid with cluster pays, meaning wins form from matching symbols anywhere on the board rather than along fixed lines. Cascading reels tumble matched symbols away after each win, allowing fresh symbols to fall and create additional matches on the same spin. Scatter symbols in the form of FLAMING 777 trigger Hellfire Spins when 4 or more land anywhere on the board, awarding a variable number of free spins. Additional scatters landing during the feature can retrigger and extend the bonus round. Burning Seven lands as a regular symbol and acts as a persistent multiplier, with its values stacking during a spin before multiplying the final win. In the base game, this multiplier is capped at a lower value, while the bonus rooms unlock higher potential. The Devil's Cut also lands as a regular symbol but pays no direct win; instead, each one halves the pending Burning Seven total before the multiplier is applied. House Brand stamps 1 to 3 card symbols after the reels reveal and redraws them into a single high symbol to form stronger matches. It can fire multiple times on the same spin, reshaping the board dynamically. The Blast clears a 3x3 area around its hit cell after the reels reveal, creating space for fresh tumbles and leaving charged cells behind. Charged Cell appears only after The Blast clears a space, holding a 2x, 3x or 5x multiplier for the remainder of that spin. Wild Columns can turn one full reel into demons on any spin, boosting every win it joins without substituting for special symbols. In The Devil's Table bonus room, a Wild column can hold its reel for an extra free spin, creating the possibility of two columns on the board simultaneously. House Favour costs 100x bet and awards 20 to 32 free spins with increased House Brand frequency. Hellfire Deal costs 250x bet and boosts The Blast frequency for more cascading opportunities. Inferno Run costs 500x bet and favours 6 FLAMING 777 scatters for longer free-spin starts. The Devil's Table costs 1,000x bet and is the only room where Wild columns can hold their reels for bonus spins.
