Great Griffin online slot review
Great Griffin is one of Microgaming’s older slots, and its age shows. Some animations may become tiresome, but players drawn to magic and sorcery may still want to give it a look among newer alternatives.
Theme and Storyline
Great Griffin takes place in an alchemist’s laboratory, where players brew potions by landing symbols on the reels. The premise is simple, but its occult and magic-inspired elements may appeal to slot fans. The title character is a huge, eagle-like bird that regularly flies in to add Wild symbols.
Graphics, sound and animations
As an older game, Great Griffin’s graphics, sounds and animations don’t match newer Microgaming releases. Still, it has held up reasonably well over the years. Its visual style is notably dark and muted, which may put some players off, especially beside newer slots with brighter, more eye-catching colours.
The main animation shows the griffin flying into view and adding Wild symbols to the reels. It may appear every few spins, interrupting the pace, and its Wild does not necessarily create a win. The sound of its arrival can also wear thin, making the mute option an understandable choice.
Top Casinos to Play Great Griffin:
Gameplay
Great Griffin offers more variety than its straightforward theme might suggest. After a favourable result, players can try to double their winnings by risking them on a card guess. This optional gamble puts previously won funds at risk, so it may not appeal to everyone.
The reels feature colourful symbols such as a spell book, a bird feather and a glowing potion. The griffin’s arrival tends to draw attention: its Wild symbol can double the amount won on a spin and increase the balance, but this is only a possibility, not a guaranteed outcome.
Hooded Lady symbols also play a key role in Great Griffin. Landing three on the reels triggers the Pick Me Bonus, where players choose a prize by selecting one of the symbols. The feature offers the chance of a sizeable win.
The Great Griffin logo is the scatter symbol. Landing at least three logos on screen starts free spins, with a choice of spin packages available, as described in the next section of this Great Griffin slot review.
Bonuses and free spins
As noted above, three Great Griffin logo scatters trigger free spins. Choose 15 free spins with a 3x multiplier, 10 with a 5x multiplier, or five with a 15x multiplier.
The Pick Me Bonus and card-guess gamble add variety to Great Griffin’s bonus options.
Bet sizes, RTP and variance
Great Griffin’s RTP is listed at close to 97 per cent, near the upper end of slot-game figures. This theoretical long-run measure does not predict individual results. Its medium variance is in line with many Microgaming releases from this period. Stakes are relatively accessible: players can choose one to 10 coins per line, up to a maximum bet of 500 coins per spin.
Conclusion
Casino Ideal’s verdict: Great Griffin may appeal to slot fans interested in magic or the occult. For a game of its age, its bonus features and free spins have appeal, though the graphics and animations look dated. The high RTP figure may catch your eye, but it cannot guarantee results; some players may prefer to explore newer slots.
