Head to the depths of the ocean in search for a jackpot in Orca, a sea life-themed slot from Novomatic. Available to play on all devices, this 5 reel, 50 payline game comes with jackpots of 50,000 coins and a free spins feature where an extra wild is added on each free spin. Play, on all devices, from between 50p and £50 per spin.

Orca is a little unusual for a Novomatic slot in that it’s played using a 50 payline game engine. The design is also a step up from many of the developer’s fruit machine reboots – the ocean floor, complete with assorted fish and plankton forms the backdrop to the reels.

Joining the A to 9 playing cards are 2 different fish, a group of penguins and a pride of sea lions. The most rewarding symbol is the mighty killer whale – land 5 of these on a single payline and you’ll win 20 times your total stake. Fill the whole of the reels with matching killer whale symbols and you’ll pocket a bumper jackpot that’s equal to 1,000 times your total stake!

Joining the standard aquatic-themed symbols is a Mayan-style mask which is the wild. We’re not sure how this sneaked in here given the theme. All you need to know is that it can land on all reels and replaces every symbol bar the scatter.

The whale’s tail is the scatter – land 3 of these on reels 1, 2 and 3 and you’ll win a payout of 4 times your total stake. You’ll also trigger the Free Games feature and with it, 10 free spins. Watch out here for the extra wilds that land on reels 2, 3, 4 and 5 on each free spin. By the final few free spins the added wilds can have a big impact. Land the scatter on reels 1, 2 and 3 during the feature and another 5 free spins are added to your tally (taking your total to 15).

Orca is 1 of the ocean’s biggest predators. These waters can be choppy for your bankroll too – this is a pretty volatile slot so expect some big swings. If you have the bankroll to cope with that then there’s plenty to like in Orca.

The design is good complete with the roar of the ocean in the background. The features are simple enough but can really deliver. If the added wilds fall nicely in the feature round, this killer whale can deliver some deadly results. If you like games based on whales, Playtech’s Great Blue is a must.
