Red-dust desert flats run to the horizon behind a rust-streaked steel reel frame, heavy-metal drums push through the cabinet speakers, and two factions of characters glare out across a six-reel, five-row grid. Metal Frontiers is Mascot Gaming’s dystopian war slot, a pays-anywhere video slot where every symbol on the paytable carries an implicit faction colour and two separate Bonus Games route out of the same screen depending on which faction fills first.
Red-tagged badges and green-tagged badges stack independently on the reels, and five or more of either colour in a single spin fires the player into a bonus round where only symbols of the active colour contribute and every new-arriving symbol sticks to its cell until the round ends.

Wins are awarded for identical symbols appearing anywhere on the 6 by 5 grid, regardless of position or adjacency. Every symbol type pays across four count brackets: 7-9 matches, 10-14 matches, 15-19 matches, and 20-30 for the maximum grid-filling clusters. Only the highest bracket paid per symbol type counts per spin. The total bet is withdrawn on each spin and the layout mirrors the studio’s recent cluster-style grids without any fixed-payline overlay.
Every paying symbol visually carries a faction colour. The red team is fronted by a red-and-white mech at 200.00 for a 20-30 cluster at the 5.00 default stake, a black-haired male lead at 100.00, and a white-haired female lead at 50.00. The green team fronts with a green battle mech at 20.00, a green-clad soldier at 16.00, and a green-accented female character at 12.00. Below both teams sits a quartet of metallic card-suit icons (heart, diamond, spade and club in gold) that share the lower tier.
Two separate Badge symbols appear across the reels, one in red livery and one in green. Each Badge carries a random multiplier value visible on its face and applies that multiplier exclusively to wins from symbols of its own colour. If several red Badges land during a spin their multiplier values sum together and apply to red-symbol wins; green Badges do the same for green. The separation is strict: a red Badge cannot boost a green symbol win and vice versa.
Five or more Badges of the same colour appearing on a single spin trigger the corresponding Bonus Game. Red opens with 2 bonus spins; green opens with 3. Inside the Bonus Game only symbols of the active faction colour appear on the reels, and every new landing of that colour sticks to its cell for the remainder of the round. Every winning spin resets the bonus-spins counter back to its starting value, and the round closes once a spin produces no new sticky landing and the counter hits zero. Final winnings are calculated once the entire bonus has played out.
The Buy toolbar offers three direct-purchase cards that swap between the two colours and bonus configurations after every main-game spin, plus a rotating Special Offer at discounted prices. The Risk toolbar becomes available after any winning round and climbs a multiplier ladder toward the game’s 5,000x total-bet peak payout.
Metal Frontiers runs on a 6-reel, 5-row grid on a pays-anywhere payment model. A spin awards wins for every symbol type that has 7 or more copies visible on the grid at once, regardless of position or adjacency. Only the highest count bracket paid per symbol type counts per spin. The cabinet places stake controls on the bottom toolbar with a central spin button driving each round.
The paytable values shown reference a 5.00 default bet. Edit the stake and the win column moves by the same proportion. Cluster sizes bracket into four tiers.

Red and Green Badges drop in across both the base round and the Bonus Games. Each Badge carries a visible random multiplier value on its face. Same-colour Badges on the same spin sum their multiplier values together and apply the total only to winning symbols of that same colour. Badges do not pay on their own; a Badge outside of any matching-colour cluster contributes nothing to the spin total.
| Element | Red Bonus | Green Bonus |
|---|---|---|
| Trigger | 5+ Red Badges on one spin | 5+ Green Badges on one spin |
| Starting spins | 2 | 3 |
| Active symbols | Red-faction only | Green-faction only |
| Sticky rule | Every new landing locks to its cell | Every new landing locks to its cell |
| Counter reset | Each winning spin resets to 2 | Each winning spin resets to 3 |
| End | No new landing, counter at 0 | No new landing, counter at 0 |
The Buy toolbar carries three purchase cards that swap between Red 2-spin, Green 3-spin and Special Offer prices after every main-game spin. Purchased Bonus Games are played using the stake locked in at purchase. The Risk option gambles any current spin-win up the studio’s tiered multiplier ladder, capped at 5,000x the total bet at the top tier. Neither path is accessible with autoplay engaged.
The declared RTP figure is 95%. Volatility runs high, with the upside concentrated in long sticky-symbol Bonus runs where red-faction premiums pile up on a single colour-locked grid and red Badge multiplier values sum together against them. Peak reachable payout on a single round is 5,000x the total bet, reachable via the Risk Wheel ladder.
Atmosphere-first dystopian war slot with a distinctive dual-routing Bonus Game. Red and Green Badges trigger separate sticky colour-locked rounds (2 or 3 starting spins) with counter-reset mechanics. Graphics and heavy-metal soundtrack are a clear production step up for the studio. 95% RTP, 5,000x ceiling via the Risk Wheel. Rated 3.6 out of 5.
Metal Frontiers is an atmosphere-first slot. The art direction, soundtrack and pacing work together to sell a post-apocalyptic wasteland better than almost anything else in the studio’s 2025 lineup, and the heavy guitar score sits right on the edge of being too much. On a good run, the soundtrack feels earned. On a bad run, it starts to grate, so the mute toggle is worth knowing where to find. The graphics hold up at the cabinet size the studio are clearly targeting, and the two-faction art direction keeps the 6 by 5 grid from feeling visually busy despite the pays-anywhere model.
The standout design choice is the dual Bonus Game routing. Five Red Badges routes the player into a 2-spin sticky Red-only round with counter-reset on every win; five Green Badges routes into a 3-spin sticky Green-only round on the same terms. The asymmetric starting spin count is what gives the two modes their distinct risk profiles. Green opens longer but against a lower-paying premium ladder. Red opens shorter but the red mech sits at 200.00 for a full cluster at 5.00 stake, which is four times the green mech’s ceiling. The Bonus Games resolve fast, which is good news on a quiet run and a mixed blessing on a hot one, since the round can close out before a second wave of sticky landings has time to build up.
A direct Buy at 750 on the 5.00 stake (Red Bonus, 2 starting spins) returned 1,032.00 on a single purchase on our run. The Special Offer card surfaces a discounted Red or Green purchase after almost every main-game spin at around 235 to 245, which is a significant price gap from the flat-rate 750 Red purchase. Whether the discounted offer or the full-price card is the better value depends on how the Badge multipliers resolve on the starting spin; neither option carries a written expected-return figure.
Metal Frontiers is a solid mid-tier release lifted by presentation. The dual-routing Bonus Game is the most distinctive thing in the product, and the pays-anywhere engine combined with colour-gated Badge multipliers gives the maths enough shape to keep the base round engaging between bonus trips. The 5,000x ceiling is earned via the Risk Wheel rather than the Bonus Games, which is worth knowing going in. Rated 3.6 out of 5.
