Great Griffin Slot Review - Microgaming Fantasy Slot

Provider	Microgaming

Step into a gothic world of alchemy and mythical beasts with Great Griffin, a 5-reel, 50-payline video slot from Microgaming. Released as part of the developer's classic fantasy catalogue, this slot draws players in with its dark laboratory atmosphere, arcane symbols and the legendary griffin at its heart - a creature that is both wild symbol and your most reliable ally on the reels. With an RTP of 96.79% and a pick-your-own-free-spins bonus that lets you trade quantity for multiplier size, Great Griffin rewards players who like a bit of strategy with their spinning.

Game Overview

Great Griffin runs on 5 reels and 4 rows with 50 fixed paylines. The RTP sits at a solid 96.79%, which is above the industry average and makes this a respectable choice for longer sessions. Volatility is rated medium, so you can expect a reasonable mix of smaller regular wins alongside the bigger feature payouts rather than long dry spells followed by occasional explosions. Bets range from £0.01 to £50 per spin, covering recreational players and higher-stakes regulars alike.

Theme and Design

Great Griffin leans into gothic fantasy with confidence. The backdrop is a darkened alchemist's study, complete with stone walls, flickering candlelight and shelves stacked with spell books and glass vials. On the reels you will find a range of symbols that fit the setting neatly - ornate gems, potion bottles, ancient tomes and mystical artefacts alongside the higher-paying card suit symbols. The griffin itself is rendered in impressive detail, a winged lion-eagle hybrid that dominates the wild symbol position and periodically swoops across the screen during the random wild bonus. It is not the flashiest slot visually by today's standards, but the art style has a coherent identity and holds up well as a piece of atmospheric slot design.

Features

Griffin Wild Symbol

The griffin acts as the wild, substituting for all standard symbols on the reels. Any win that includes the griffin wild pays double the standard amount - a consistent 2x boost that keeps the base game feeling generous. Land five griffin wilds on a payline and you collect 5,000 coins at that coin value.

Griffin Wild Bonus (Random Feature)

At any point during the base game, the griffin can randomly fly across the reels and transform one or more standard symbols into wilds. This random trigger adds a layer of excitement to every spin, since a dull-looking set of reels can suddenly become profitable when the griffin decides to appear.

Free Spins - Your Choice

Land three or more Great Griffin logo scatter symbols anywhere on the reels to trigger the free spins bonus. The key mechanic here is that you get to choose how you want to play the feature:

5 free spins with a 10x multiplier - high risk, high reward. A small number of spins, but every win is multiplied tenfold.
10 free spins with a 5x multiplier - a balanced option that suits most playing styles.
15 free spins with a 3x multiplier - the safer pick. More spins to work with and a consistent 3x boost on every payout.

All three options can deliver significant wins, but the choice makes Great Griffin more engaging than slots that simply assign a fixed number of spins. Three scatter symbols also pay up to 5x your total bet as a scatter award before the feature even starts.

Hooded Lady Pick Me Bonus

The hooded lady is a second scatter symbol that only appears on reels 2, 3 and 4. Land three of them simultaneously and you trigger the Pick Me bonus game. Here you select from a group of hidden prizes to reveal instant cash awards, with payouts reaching up to 150x your total bet. It is a shorter feature than the free spins round, but it can deliver a punchy reward quickly.

How to Play

Set your bet using the coin size and coins-per-line controls at the bottom of the screen. With 50 paylines active, your total spin cost is 50 multiplied by your coin value and number of coins. Hit Spin or use Autoplay to set a run of consecutive spins. Watch for the griffin wild flying across reels during the base game - it is the visual cue that the random wild feature has triggered. For the bonus rounds, keep an eye on both scatter types: the Great Griffin logo across any positions for free spins, and the hooded lady strictly on reels 2, 3 and 4 for the Pick Me round. When the free spins choice screen appears, take a moment to consider your preference. The 10x multiplier option is the highest-variance path; the 15-spin option suits players who want more time in the feature.

Our Verdict

Great Griffin is a well-crafted Microgaming slot that does not overload players with complicated mechanics but still provides genuine decision-making in the free spins choice screen. The 96.79% RTP is one of its strongest selling points, and the medium volatility means neither camp - cautious players nor those chasing bigger hits - will feel entirely out of their comfort zone. The random griffin wild feature keeps the base game lively, and the double-or-nothing character of the 5x10 multiplier free spins option gives the slot a memorable high point. If you enjoy fantasy-themed slots from a reliable developer and want solid long-term return potential, Great Griffin earns a firm recommendation.
