Great Griffin Online Slot Review
Great Griffin is an early Microgaming slot, and its age is showing. Some animations may become irritating, but players drawn to magic and sorcery may still find it worth exploring alongside newer alternatives.
Theme and Storyline
Great Griffin takes place in an alchemist’s laboratory, where landing symbols on the reels is like brewing potions. The premise is simple, but its occult and magic-inspired themes may appeal to slot fans. The title character is a massive eagle-like bird that regularly enters the action to add Wild symbols.
Graphics, sounds and animations
Given its age, Great Griffin’s graphics, sounds and animations don’t match newer releases from studios such as Microgaming. Still, the game has held up reasonably well over the years. Its visual design is notably dark and drab, which may put off some players, especially when newer slots often use brighter, more eye-catching colors.
The main animation shows the griffin flying into view and adding Wild symbols to the reels. It may appear every few spins and interrupt the pace, while a Wild does not necessarily result in a win. The sound that accompanies its arrival can also grow tiresome, making the mute option useful.
Top Casinos to Play Great Griffin:
Gameplay
Great Griffin offers more variety than its simple theme might suggest. When the reels produce a favorable result, players can choose to risk their winnings on a card guess for a chance to double them. That gamble won’t suit everyone, as previously won funds are at risk, but it’s optional.
The reels feature colorful symbols such as a spell book, bird feather and glowing potion. The griffin’s arrival tends to stand out: its Wild symbol can double the amount won on a spin and increase the balance. This is a possibility, not a guaranteed result.
Hooded Lady symbols are another key part of Great Griffin. Landing three on the reels activates the Pick Me Bonus, where players choose a prize by selecting one of the symbols. The feature offers the possibility of a sizeable win.
The Great Griffin logo is the game’s scatter symbol. Landing at least three logos on screen triggers free spins, with a choice of spin options described in the next section of this Great Griffin slot review.
Bonuses and free spins
As noted above, landing three Great Griffin logo scatters triggers free spins. Choose from 15 free spins with a 3x multiplier, 10 free spins with a 5x multiplier, or five free spins with a 15x multiplier.
The Pick Me Bonus and card-guess gamble add variety to Great Griffin’s bonus options.
Bet sizes, RTP and volatility
Great Griffin’s RTP is listed as close to 97 per cent, near the upper end of slot-game figures; this theoretical long-run measure does not predict an individual result. Its medium variance is in line with many Microgaming releases from that period. Stakes are relatively accessible: players can select one to 10 coins per line, up to a maximum bet of 500 coins per spin.
Conclusion
Al Buraq Regina’s assessment: slot fans interested in magic or the occult may enjoy Great Griffin. For a game of its age, its bonus features and free spins are appealing, though the graphics and animations look dated. The listed RTP may attract attention, but it cannot guarantee results, and some players may prefer to explore more modern slots.
