What Is Inferno Devil 100?
Inferno Devil 100 is Fugaso placing their DAY 2 DAY™ progressive jackpot engine inside a classic fruit machine dressed in hellfire. The reels sit inside a slot machine adorned with devil horns and tuning forks, animated flames lick the background, and a sinister soundtrack hums throughout. The symbols are pure fruit machine — cherries, lemons, oranges, plums, watermelons, grapes, bars, stars, and lucky 7s in red and yellow — with a laughing red Devil wild and a golden Bell scatter as the special symbols.
The 5×4 grid with 100 fixed paylines gives the game much wider payline coverage than a standard 5×3 setup, and the stacking Devil wild can fill entire reels when it hits, compounding wins across multiple simultaneous paylines.
The DAY 2 DAY™ jackpot fires randomly — no combination required. When it triggers, the game pauses for approximately 30 seconds and a treasure chest reveals one of three jackpot prizes. A rare secondary jackpot can appear during that same freeze window, worth 10% of the just-won jackpot (re-seeded). Higher bets increase the probability of triggering the jackpot on any given spin.
Fugaso positions this as a sequel/enhancement to their earlier Inferno Diamonds title — the same fruit-in-hell concept with an added row of symbols and 100 paylines instead of the smaller original format.
RTP and Volatility
Inferno Devil 100 carries a combined RTP of 96.5% made up of two distinct components:
- Base game RTP: 92% — theoretical return from standard payline and scatter wins only
- Jackpot contribution RTP: 4.5% — theoretical return from the progressive jackpot pools, distributed across all winning jackpot events
This split is confirmed by VegasSlotsOnline and LCB.org. It’s important because a player who never wins any jackpot tier during their session effectively experiences the game at 92% RTP — well below the 96% benchmark. The 96.5% headline is the long-run average across millions of spins including jackpot winners.
Volatility is medium-high, confirmed by Blackspins, VegasSlotsOnline, and gamesandcasino.com. The 18% hit frequency (roughly 1 in 6 spins pays) is lower than medium-volatility norms and consistent with the medium-high classification. Expect extended base-game dry runs punctuated by Bell scatter pays and, occasionally, the random jackpot trigger.
Jackpot contribution per bet:
| Pool | Contribution per spin |
|---|---|
| Mini | 2% of total bet |
| Midi | 1.5% of total bet |
| Maxi | 1% of total bet |
| Total | 4.5% of total bet |
At $1.00 per spin, $0.045 goes to jackpot pools every spin. At $100 maximum, $4.50 per spin feeds the pools.
Betting Range
Inferno Devil 100 accepts bets from $0.20 to $100.00 per spin across 100 fixed paylines. All paylines are always active.
Jackpot probability scales with bet size — Fugaso explicitly confirms higher bets increase the odds of triggering any jackpot tier. At $0.20 minimum, jackpot probability is at its lowest floor. At $100 maximum, the probability per spin is significantly higher while $4.50 goes to the jackpot pools per spin.
The 5,000× maximum win scales with stake: at $100, the maximum payout is $500,000. At $0.20, the same win is $1,000.
Autoplay is available.
How to Play Inferno Devil 100 — Step by Step
- Set your bet. Choose between $0.20 and $100.00. All 100 paylines are fixed. Note that higher bets increase your jackpot trigger probability while also increasing your jackpot pool contribution per spin.
- Open the paytable. Review the Bell scatter pay schedule (3 = 4× total bet; 4 = 20× total bet; 5 = 200× total bet), the Devil wild behaviour (substitutes + stacks on reels), and the regular symbol values.
- Press spin. Left-to-right combinations from reel 1 across any of the 100 paylines. With 5×4 = 20 symbol positions and 100 paylines, the grid is dense with potential payline crossing.
- Devil wild (stacking). When the Devil appears and stacks on a reel, it fills multiple row positions with wilds simultaneously — a fully-stacked Devil reel provides four wild positions on that reel, crossing all paylines that pass through it. Substitutes for all regular symbols (not Bell scatter).
- Bell scatter. Pays directly anywhere on the 20-position grid regardless of payline. 3 bells = 4× total bet; 4 bells = 20×; 5 bells = 200×. Only the highest scatter win counts per spin.
- DAY 2 DAY™ Jackpot. Fires randomly on any spin. If triggered: the screen freezes, a treasure chest appears, and a jackpot prize (Mini, Midi, or Maxi) is revealed. During the ~30-second freeze, there’s a rare chance a second jackpot fires (worth 10% of the previous jackpot, re-seeded). The jackpot amounts currently accumulating are displayed on a visible board on the screen.
Do this: Before each session, check the displayed jackpot pool values on-screen. If the Maxi jackpot is unusually large (substantially above its typical seeded value), it indicates the pool has been accumulating without a recent winner — this doesn’t change the per-spin probability, but it does mean the potential payout is larger than average if the trigger fires.
Symbols and Paytable
Inferno Devil 100 uses a full classic fruit machine symbol set with two hell-themed special symbols layered on top.
Low-value fruit symbols: Cherries, lemons, oranges, plums — the paytable base; require 3+ on a payline for small payouts. Slotbeats confirms these pay between 0.05× and 2.5× bet for varying counts.
Medium-value symbols: Watermelons, grapes — mid-tier; Slotbeats reports 0.1× to 5× bet range for 2–5 of a kind.
High-value classic symbols: Bar, star, red 7, yellow 7 — Slotbeats confirms 0.5× to 12.5× bet range for these symbols at 2–5 of a kind.
Devil — Wild (stacking): The red laughing Devil is the game’s wild symbol and its highest-paying payline symbol. Substitutes for all standard symbols. Can appear stacked on reels — a fully-stacked Devil covers all four row positions on its reel, providing four simultaneous wild positions for every payline crossing that reel. Pays on its own payline when 3+ appear.
Bell — Scatter: Golden Bell. Pays anywhere in view on the 5×4 grid, independent of payline alignment. Pay schedule: 3 bells = 4× total bet; 4 bells = 20× total bet; 5 bells = 200× total bet. Only the highest scatter win is counted per spin. The 200× five-bell scatter pay is the standard (non-jackpot) highest single-event payout available.
Watch for: A stacked Devil appearing on reels 2 and 4 simultaneously when a high-value symbol (red 7, bar, or star) is present on reels 1, 3, and 5. On a 100-payline 5×4 grid, stacked wilds on two middle reels bridging premium symbols on the three outer reels produce compound payline wins across many of the 100 active lines simultaneously — the game’s highest possible base-game payline event.
Bonus Features
Stacking Devil Wild
The Devil wild can appear as a standard single symbol or in a stacked configuration that covers multiple rows on the same reel. When a full reel stack occurs (four Devil positions on one reel), all four rows of that reel are wild for every payline passing through — on a 100-payline grid, a single stacked wild reel activates wild coverage for a large proportion of active paylines at once.
The wild’s own payline value (when 3+ Wilds form a payline combination) adds to line wins on top of any substitution wins. Verify the exact per-combination payout for 3, 4, and 5 Devils in the in-game paytable.
Bell Scatter — Direct Pay
The Bell scatter pays directly on 3, 4, or 5 appearances anywhere on the 5×4 grid (20 positions):
- 3 bells = 4× your total bet
- 4 bells = 20× your total bet
- 5 bells = 200× your total bet
These are added to line wins for the same spin. The 200× five-bell pay is the highest single base-game outcome after the Devil wild’s own top payline combination.
DAY 2 DAY™ Jackpot (Mini, Midi, Maxi)
Trigger: Random on any base-game spin. Cannot be triggered during the standard symbol evaluation — it’s an independent overlay event.
When triggered, the reels freeze and a treasure chest appears on screen. The chest reveals the awarded jackpot tier. The screen remains frozen for approximately 30 seconds. During this freeze window, in rare circumstances, a second jackpot can trigger — this second award is worth 10% of the just-won jackpot amount (re-seeded after the primary win).
Jackpot pool mechanics:
- Mini, Midi, and Maxi pools each accumulate from 2%, 1.5%, and 1% of every spin respectively
- Current pool values are displayed on the screen during gameplay
- Higher bets increase the probability of triggering any tier per spin
- All real-money players contribute to and compete for the same shared pools
This is the same DAY 2 DAY™ system used in Hit the Diamond and Diamond Blitz 100 — Fugaso’s standard progressive jackpot architecture across their classic-themed catalogue.
Design and Theme
The visual concept is classic fruit machine possessed by the devil. The slot machine itself — visible on screen — is styled with devil horns and tuning forks, flames animated in the background, lava glowing below. The dark reels hold shiny, vibrant fruit symbols that pop against the sinister backdrop.
The Devil wild is visually the centrepiece — a red, laughing, cartoonishly malevolent figure that becomes an unmissable event when it appears stacked on a reel. The Bell scatter uses a golden glow to stand out from the standard fruit symbols.
The soundtrack runs an intense, sinister undertone that complements the theme without becoming oppressive. Win animations use flame effects.

Is Inferno Devil 100 Worth Playing?
Pros:
- 96.5% combined RTP is above the 96% benchmark at face value
- 5×4 grid with 100 fixed paylines gives maximum payline density — stacked wilds affect far more lines simultaneously than on a 5×3 format
- Bell scatter pays 200× total bet for 5 of a kind anywhere — a meaningful base-game payout independent of jackpot wins
- Stacking Devil wild adds genuine excitement to every wild appearance — a full reel stack is a visually dramatic and mechanically significant event
- DAY 2 DAY™ jackpot uses Fugaso’s proven random-trigger architecture with a rare secondary jackpot bonus during the freeze window
- 5,000× maximum win is achievable via jackpot or combined wild+scatter events
- $0.20 minimum stake provides access to the progressive jackpot pools at very low cost per spin
Cons:
- Base-game RTP is only 92% — the 96.5% headline figure is entirely dependent on jackpot contributions; players who don’t win a jackpot tier experience a 92% return game, well below the 96% benchmark
- Hit frequency of 18% (~1 in 6 spins) is relatively low for medium-high volatility — sessions without jackpot hits can feel lean
- No free spins or traditional bonus round — the jackpot is the sole bonus event and it fires randomly
- Jackpot probability scales with bet size, creating unequal odds between minimum-stake and maximum-stake players
- 4.5% of every spin’s total bet goes directly to jackpot pools — this is a large per-bet cost for players who don’t win jackpots
Inferno Devil 100 is a well-executed DAY 2 DAY™ jackpot fruit pokie with an atmospheric hell theme, a genuinely impactful stacking wild, and a visually satisfying Bell scatter. The honest limitation is the 92% base-game RTP — it’s only the progressive jackpot contributions that lift the headline to 96.5%, and that headline figure is an average across all players including jackpot winners. Approach this game as a jackpot slot where the base game carries a below-average return, not as a 96.5% fruit machine with bonuses. If that trade-off suits your play style, the 5×4 100-payline format and stacking wilds make each session genuinely dynamic.
Responsible Gambling
Inferno Devil 100 uses a certified random number generator (RNG). All reel outcomes, wild positions, Bell scatter appearances, and DAY 2 DAY™ jackpot trigger events are fully random and independent between spins. The 96.5% RTP is a combined long-run theoretical figure including jackpot wins; base-game returns average 92%.
