What Is Inferno Diamonds?
Inferno Diamonds is Fugaso’s original entry in their inferno-themed fruit machine series — the foundational version before the grid expansions. It runs on a 5×3 frame (the classic three-row layout) with 20 paylines, the same burning-diamond wild and golden-bell scatter found across the series, and the same DAY 2 DAY™ jackpot overlay that can fire at any moment on any spin.
The visual tone is described as dark brownish — a darker, more subdued palette than the purple backdrop of Inferno Diamonds 100, giving it a slightly more vintage slot machine atmosphere. The frame around the reels is an old-fashioned slot machine cabinet. Jackpot pool meters are displayed to the left of the reels throughout play.
Where Inferno Diamonds 100 expands the grid to 5×4 and packs in 100 paylines, this original stays deliberately compact. Twenty paylines on a 5×3 grid creates a simpler, more traditional session feel — fewer simultaneous payline interactions per spin, clearer win readability, and medium (rather than medium-high) volatility. The lower payline count also means the maximum win from all-five-wild coverage is 1,500× rather than 5,000×.
No free spins. No bonus rounds. The Diamond wild and Bell scatter handle the payline and scatter pay events; the DAY 2 DAY™ jackpot handles everything above standard play.
RTP and Volatility
Inferno Diamonds carries a combined RTP of 96.5% made up of the same two components as all Fugaso DAY 2 DAY™ titles:
- Base game RTP: 92% — return from standard payline and scatter wins only
- Jackpot contribution: 4.5% — theoretical return distributed across jackpot winners
This is explicitly acknowledged in the Blackspins body text: “Boasting a robust RTP of 92%, augmented by an additional 4.50% for the jackpot feature.” Players who never win a jackpot tier during their session experience a 92% return — below the 95% benchmark most players use as a floor.
Volatility is medium, confirmed consistently across Blackspins, SlotJudge, list.casino, and LCB.org. The 5×3 format with 20 paylines produces more regular but smaller wins than the expanded 100-payline version, giving the session a steadier rhythm even if the absolute payouts are lower. There’s no published hit frequency figure for this version; the 100-payline variant runs at 18%, and the compact 20-payline version likely sits similarly or slightly higher due to the reduced grid complexity.
Jackpot contribution (same rates as all DAY 2 DAY™ titles):
- Mini pool: 2% of each bet
- Midi pool: 1.5% of each bet
- Maxi pool: 1% of each bet
At $1.00 per spin, $0.045 goes to jackpot pools. At $100 maximum, $4.50 per spin.
Betting Range
Inferno Diamonds accepts bets from $0.20 to $100.00 per spin across 20 fixed paylines. All 20 are always active.
Jackpot trigger probability scales with bet size — explicitly confirmed by Blackspins (“the higher the stakes, the greater the likelihood of securing a jackpot”). The current pool values for Mini, Midi, and Maxi are displayed on the left side of the reels at all times.
At $100 maximum, 1,500× = $150,000. At $0.20 minimum, 1,500× = $300.
Autoplay is available.
How to Play Inferno Diamonds — Step by Step
- Set your bet. Choose between $0.20 and $100.00. All 20 paylines are fixed and always active.
- Open the paytable. Check the Diamond wild’s own payline values (3, 4, 5 diamonds), the Bell scatter pay schedule (3 = 4×, 4 = 20×, 5 = 200× total bet), and the regular symbol hierarchy.
- Check the jackpot meters. Displayed on the left of the reels. Note current Mini, Midi, and Maxi pool sizes.
- Press spin. Left-to-right combinations from reel 1 on any of the 20 paylines. The 5×3 grid has 15 symbol positions.
- Diamond wild (stacking). When a Diamond stacks on a reel, it can cover multiple row positions simultaneously. A fully-stacked reel of Diamonds (three positions) on the 5×3 grid provides wild coverage for every payline crossing that reel. The Diamond also pays its own line win when 3+ appear on a payline.
- Bell scatter. Pays anywhere on the 15-position grid: 3 bells = 4× total bet; 4 bells = 20× total bet; 5 bells = 200× total bet. DAY 2 DAY™ Jackpot. Fires randomly on any spin. No symbol trigger required. Game freezes; treasure chest reveals Mini, Midi, or Maxi jackpot. The rare secondary jackpot can also fire during the same freeze window.
- Maximum win (1,500×). Requires Diamond wilds covering all five reels across all 20 paylines — or maximum Bell scatter pay combined with near-full wild coverage.
Do this: Because the 5×3 grid has only 15 positions (vs 20 in the 4-row version), scatter events are statistically more concentrated. On this smaller grid, even 3 Bell scatters across 15 positions represents a meaningful proportion of the grid being occupied by a single scatter symbol. Track Bell frequency in your first 20 spins — the scatter is both a direct-pay event and your best base-game value source outside of the stacking wild.
Symbols and Paytable
Inferno Diamonds uses 8 total symbols — 6 regular plus two special (Diamond wild and Bell scatter). This is fewer than the 10 regular symbols in Inferno Diamonds 100, reflecting the compact 5×3 format.
Regular symbols (from Blackspins and LCB.org): Red 7, gold 7, star, BAR, lemon, watermelon, cherry. Values range from the lower fruit symbols up to the 7s at the premium end of the regular paytable.
Diamond — Stacking Wild: Burning diamond symbol. Substitutes for all 6 regular symbols to complete payline combinations. Can appear stacked, covering all three row positions on a reel. When five Diamonds cover a full five-reel payline, the payout is the Diamond wild’s own value at 50× per payline. With 20 paylines, full five-reel wild coverage produces up to 1,000× via paylines (50× × 20) — the remaining 500× of the 1,500× maximum likely comes from the Bell scatter’s 200× combined with a partial wild arrangement, or from a specific maximum wild configuration. Verify the precise maximum in-game.
Bell — Scatter: Golden Bell. Pays anywhere in view on the 15-position grid: 3 bells = 4× total bet; 4 bells = 20× total bet; 5 bells = 200× total bet. These are added to payline wins. The 200× five-bell pay is the largest single non-jackpot outcome.
Watch for: A stacked Diamond wild on reel 3 (the central reel of the 5×3 grid). With only 3 rows, a fully stacked centre reel provides three wild positions crossing all paylines running through that column — on 20 paylines a central stacked wild affects more simultaneous lines than an edge-reel wild. Combined with premium symbols (7s or stars) on reels 1, 2, 4, and 5, this produces the game’s largest multi-payline base-game win event.
Bonus Features
Stacking Diamond Wild
Identical in behaviour to the 100-payline version but operating on the smaller 5×3 grid. A fully-stacked Diamond reel covers all three row positions with wild substitution for every payline passing through that reel. On 20 paylines this is a meaningful event, though less dramatically compounding than on the 100-payline version where the same event crosses more lines.
The Diamond wild’s direct payline value when five appear in a combination is 50× per payline. At 20 paylines maximum, this is the game’s primary base-game value driver.
Bell Scatter — Direct Pay
Golden Bell pays directly on 3, 4, or 5 appearances anywhere on the 15 grid positions:
- 3 bells = 4× total bet
- 4 bells = 20× total bet
- 5 bells = 200× total bet
The 200× five-bell event is the highest single standard base-game outcome. On a 5×3 grid with 15 positions, five simultaneous Bell scatters requires one-third of the grid to show the same symbol — rare, but meaningfully less rare than on a 5×4 20-position grid.
DAY 2 DAY™ Jackpot (Mini, Midi, Maxi)
Trigger: Fully random on any base-game spin. No symbol combination or specific event is required.
Three progressive jackpot pools accumulate continuously. The Maxi jackpot is described as a monthly prize and can reach six-figure amounts depending on network traffic and trigger timing. Jackpot values are always visible on screen.
Higher bets increase the per-spin trigger probability. The same 30-second freeze window applies, with the rare secondary jackpot possibility (10% of the first win, re-seeded) available during the freeze.
Important: Jackpot pool values are shared across multiple Fugaso DAY 2 DAY™ titles — meaning the same Maxi pool is fed by players on Inferno Diamonds, Inferno Diamonds 100, Inferno Devil 100, Hit the Diamond, and Diamond Blitz 100 simultaneously. This means pools accumulate faster than single-game progressives, but the same pool is also competed for across a larger player base.
Design and Theme
Inferno Diamonds uses a dark brownish colour palette — more muted and traditional than the purple of Inferno Diamonds 100. The reels sit inside a classic slot machine cabinet frame; the background is darker and warmer in tone. Jackpot meters glow to the left of the reels.
The symbol art is clean and shiny — fruit symbols rendered with a modern jewel-like finish against the dark background. The Diamond wild is the visual standout: a faceted burning gem that immediately identifies itself as the premium symbol. The Bell scatter uses a warm golden glow.
The soundtrack is described by list.casino as pleasant with nice beats — an upbeat electronic track. Win animations are understated and quick, consistent with the game’s pace-focused design philosophy.

Is Inferno Diamonds Worth Playing?
Pros:
- Medium volatility on a compact 5×3 grid provides a steadier session rhythm than the 100-payline versions — wins come more predictably even if they’re smaller
- Same DAY 2 DAY™ jackpot overlay as the 100-payline titles — the Mini, Midi, and Maxi tiers are accessible from the same $0.20 minimum stake
- Shared jackpot pools accumulate across multiple Fugaso titles — larger network = faster pool growth
- Bell scatter pays 200× total bet for 5 of a kind — the most impactful base-game event
- $0.20 minimum stake keeps the jackpot accessible at very low per-spin cost
- Compact 5×3 format is faster to understand and navigate than the denser 100-payline grids
- Fugaso holds MGA and UKGC licences — regulated developer
Cons:
- Base-game RTP is 92% — same as the 100-payline versions; the 96.5% headline requires jackpot wins to be realised and is not a base-game figure
- Maximum win of 1,500× is lower than either 100-payline variant (5,000×) — the smaller grid limits the wild compounding ceiling
- No free spins, no bonus rounds — the feature set is minimal by modern standards
- 20 paylines provides less payline coverage than the wider-grid variants; stacked wild events affect fewer simultaneous lines
- Closely related to multiple other Fugaso DAY 2 DAY™ titles with essentially the same mechanics
Inferno Diamonds is the compact, medium-volatility entry point into Fugaso’s inferno fruit machine series. If you’re new to the DAY 2 DAY™ jackpot format and want to understand how it works on a familiar 5×3 frame before trying the denser 100-payline versions, this is the natural starting point. The 92% base-game RTP is the honest limitation shared across all three titles — accept it as a jackpot slot where the base game carries below-average return, and the headline 96.5% reflects long-run averages including jackpot distributions. Within those parameters, Inferno Diamonds is a well-executed, visually clean classic fruit pokie.
Responsible Gambling
Inferno Diamonds 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% combined RTP is a long-run theoretical average including jackpot wins; the base-game return averages 92% independently.
