Gryphon's Castle Deluxe Slot by Mascot Gaming

Six Years Later, the Gryphon Returns

Mascot Gaming released the original Gryphon's Castle back in 2019. The Deluxe version arrived in November 2025 - the same fantasy castle setting, same gryphon mascot, but rebuilt with a new headline mechanic and a revamped paytable. If you played the original, the biggest thing you'll notice immediately is the RTP shift: the base game ran at 96.6%, the Deluxe version sits at 94.74%. That's a meaningful drop, and it's worth knowing upfront.

The grid stays 5x3 with 20 fixed paylines. Bets run from €0.20 to €40.00 per spin, giving a decent spread whether you're testing at minimum or playing at real stake sizes.

The Symbol Set

The top premium is a skull wearing a crown - slightly macabre for a fantasy theme, but it works visually. This symbol pays on just two of a kind: two skulls anywhere on a payline returns 5x the line bet, three pays 75x, four pays 750x, five pays 1,500x. That 2-symbol payout on the top symbol is a nice touch for base game frequency. The second-highest premium, a golden gryphon signet ring, also pays on two (4x), making these two symbols noticeably more active than most top symbols in standard 5-reel slots.

The scatter is a glowing dragon eye encased in a glass orb. Two scatters pay 2x your total bet without triggering anything further. Three, four, or five scatters pay 5x, 10x, and 35x respectively - and trigger Free Spins. Below the premium tier, four lower symbols fill positions six through nine: stylized card suit icons (hearts, spades, diamonds) that pay 10x for three of a kind, scaling to 100x for five.

Expanding Wild Reel

This is the main mechanical upgrade over the original. When a wild symbol appears during the base game, it expands to cover its entire reel. The game announces it on screen: "on reel X expands to cover the entire reel!" You saw this in action almost immediately - the first spin in this review landed an expanding wild on reel 3.

A full-reel wild on any of the five columns transforms a lot of symbol combinations. On reel 3 specifically, it affects every payline that passes through the middle column - which is all 20 of them. On reels 1 or 5, the impact is narrower but still meaningful. The mechanic isn't unique to this game (plenty of slots use expanding wilds), but the execution is clean and it fires visibly in the base game rather than being locked to bonus rounds only.

Free Spins: 15 Rounds, 3x Throughout

Three or more scatters anywhere on the reels trigger 15 free spins. A static 3x multiplier applies to every win during the round - not a progressive or collected multiplier, just a fixed boost applied to every payout. All wins get tripled. The expanding wild mechanic carries through as well, so a reel-wide wild during free spins, with the multiplier applied, produces the kind of numbers this game is built around.

The max win cap is 1,000x. That's low for a 2025 release - most medium volatility slots in this category advertise 5,000x to 10,000x. The 1,000x ceiling is real and was confirmed in the game's own win display. At €40.00 max bet, that translates to €40,000 maximum, which isn't nothing, but the ceiling closes off the top end faster than competitors.

Buy Feature and Risk Wheels

The Buy Feature button sits on the left side of the interface throughout the base game. Cost is 100x the current bet - so €20.00 at minimum stake, €4,000 at maximum. You get the same 15 free spins with 3x multiplier that you'd trigger naturally. Whether that price feels reasonable depends on how long you're comfortable grinding the base game for scatters.

After any win, the Risk Game becomes available. Three wheel tiers let you gamble your current win for higher multipliers. The top risk wheel can multiply a win up to the 1,000x game cap. It's a pure gamble mechanic - optional, and the payout structure follows the usual risk/reward split. Autoplay covers 10, 25, 50, 100, 150, 300 spins, or unlimited with stop conditions.

Where It Stands

Gryphon's Castle Deluxe is a competent medium volatility slot. The expanding wild mechanic works well and triggers in base game often enough to matter. The 2-symbol payouts on the top two premiums give the base game more texture than the typical wait-for-free-spins structure. And the free spins round with a fixed 3x multiplier is solid without being spectacular.

The weaknesses are real though. The 94.74% RTP is noticeably below where most modern releases land - the original Gryphon's Castle returned 96.6%, and that 1.86 percentage point gap is felt over sessions. The 1,000x max win is the other constraint: for players chasing large multipliers, this ceiling will disappoint compared to what launched alongside it in late 2025. If you liked the original, the Deluxe version is a genuine upgrade mechanically. If you're coming in fresh, just go in knowing the math is leaner than the presentation suggests.
