Great Blue Slot

The search for a ‘killer’ slot is the reason many people come to sites like this. The dizzying selection of video slots available at the best online casinos can make the hunt for such a machine seem daunting, so perhaps Playtech are hoping that by giving its Big Blue slot a Killer Whale theme it will subliminally suggest to players that this could be the ‘killer’ slot they’re after.

Well we’ve dived into its watery world to find out on your behalf if Big Blue is a truly magnificent beast or simply a bit of a wet fish.

The Big Blue basegame has twenty-five paylines to reel in the rewards from its five reels and adds a little aquatic fun to its symbol-set, giving pride of place to the mighty Orca as its highest prized catch with a Wild identity too.

This Wild Whale also appears as a stacked symbol to stir-up potential feeding frenzies on the paytable, doubling any wins it can conjure up when it substitutes for other symbols. This is nice bit of basegame bonus, which compensates for what we feel is a bit of a lacklustre presentation of this slot’s theme.

The mechanics of Big Blue are absolutely fine, but in our opinion Playtech could have been more imaginative with this online slot’s graphics and audio – the game’s theme gives loads of scope for an immersive underwater adventure, but rarely feels more that a standard casino slot with some sea life stuck on.

The Big Blue online slot sticks with a relatively simple formula when it comes to its main bonus feature activated when three to more of its Clamshell Scatter symbol fall into view at the conclusion of a spin.

An intermediate second-screen game presents players with five closed clamshells out of which two can be picked to reveal awards to complement a basic award of eight free spins with a 2x multiplier applied for this bonus round.

Each may contain additional free spins or multipliers, and the headline award is picking the clams that can award thirty-three spins with all wins plumped up with a x15 multiplier! Factor in the potential for infinite retriggers during the freespins game and Big Blue suddenly becomes a lot more interesting for big win hunters.

One final feature that helps redeem Big Blue from our earlier criticism about its rather ordinary presentation is the inclusion of an extra optional gamble feature that players can put into play when they land a win.

Based around a simple Red or Black decision, the correct prediction of the colour of the next playing card the closed clamshell in the centre of the screen will reveal can instantly double your payout.

This is an all-or-nothing wager and brave explorers of the Big Blue can continue to repeat the gamble until they decide their luck might run out and hit ‘collect’, or surface with nothing if the clam reveals a failed prediction.

We can’t honestly say Great Blue is an online slot that bubbles with innovative ideas, and teems with bonus features, however it is a perfectly decent twenty-five payline slot that delivers solid gaming entertainment.

It’s also a higher-volatility video slot that means it’s geared towards less-frequent wins but bigger paydays when they happen – if that suits your preference when playing online slots then Big Blue’s briny offering could well float your boat.
