Evil Devil is a Hell-themed video slot by Peter Sons, released in September 2024. The game drops players into a scorched underworld of crimson skies, horned devils, and gothic skulls, backed by a thunderous orchestral soundtrack.
It runs on a 6×7 grid with 117,649 ways to win, matching symbols simply need to land on adjacent reels left to right, no fixed paylines required. Bets run from $0.20 to $100 per spin, and given the very-high volatility, a bankroll of 150–200× your stake is a sensible starting point.
If Evil Devil's sticky-ways formula appeals, Gates of Olympus (Pragmatic Play, 96.50% RTP, ×5,000) is the genre benchmark.
Evil Devil, available on Gamdom, stands out on four fronts: Peter Sons' hand-crafted character animations are among the best in the mid-tier studio space; the very-high volatility rewards patient, big-swing players; the 10,000× max win ($1,000,000 cap) is a genuine headline figure; and the full demo means you can test all of this at zero cost before staking a cent.

The official RTP is 96.09%, slightly above the industry average of ~95.5–96.0%. Volatility is Very High, with a hit frequency of 17.88%; about one in six spins pays something, but meaningful wins cluster in the bonus round. The maximum win is 10,000× stake, capped at $1,000,000, with a top-prize probability of roughly 1 in 33,000,000.
Peter Sons publishes three operator configurations: 90.5%, 94.0%, and 96.1%. Casinos choose which to deploy, often without advertising the choice. Always check the in-game paytable to confirm which version is active before playing: a 5.6-percentage-point difference in long-term return is significant.
Choose from 14 preset stakes ($0.20–$100), hit spin, and the 117,649-ways engine evaluates every adjacent-reel combination automatically. Autoplay supports unlimited spins with configurable win and loss stop limits. Turbo mode speeds up animations without touching the RNG.
Sticky Respins are the headline mechanic. Qualifying symbols lock in place; remaining reels respin. Each new qualifying symbol extends the sequence and also locks, building toward a potentially board-filling payout.
Free Spins are triggered by landing sufficient scatter symbols. During free spins, the sticky mechanic runs under enhanced rules, multipliers accumulate via a skull-collect meter, and retriggers extend the round.
Bonus Buy lets players skip directly to the feature for roughly 80–100× stake, where permitted. It is unavailable in the UK and several other regulated markets.
The demo is free, requires no account, and runs the same RNG as the real-money game. Use it to observe bonus trigger frequency over at least 100–200 spins and to feel out the volatility rhythm before committing a real bankroll.
Dog House Megaways (Pragmatic Play, 96.55%, ×12,305) offers a higher multiplier ceiling in the same ways format. For a Hell-themed alternative, Burning Hot (EGT) shares the fiery, scorched aesthetic.

Yes: no account or deposit required, full mechanics included.
$0.20 minimum, $100 maximum, across 14 preset levels.
Land the required scatter symbols (typically 3+) anywhere on the reels. Sticky Respins trigger when qualifying symbols lock during a base-game spin.
Loss limits, session time limits, deposit limits, and cooling-off periods are available via the casino account settings. Set a session loss limit before you start: very-high volatility demands it. Alternatively, refer to Gamdom’s responsible gambling page.
Score: 8.5/10: Highly Recommended for High-Volatility Players
Evil Devil combines exceptional production values, a well-engineered sticky bonus, and a 96.09% RTP into one of the strongest high-volatility releases of 2024. The 10,000× max win is genuine, not inflated marketing, and the free demo means there's no reason not to try it first.
