We have to take our hats off to Playtech. Rarely do they disappoint in their ability to design a superb video slot, but in Jackpot Giant the software top dogs really have outdone themselves. There's so much to admire here, from the detailed animation to the betting range. Not forgetting that volcano bonus game where payouts come just for picking a volcano at random.

Ok, so all 50 paylines are fixed, but with stakes starting at just 50p a spin (0.01 per line) and still qualifying for the full 50, it should come as no surprise that wins on Jackpot Giant aren't in short supply. Plus, at just £4 a spin to put yourself in the frame for the jackpot, this is a progressive game that even smaller bankroll players can get behind.

Symbols in the Jackpot Giant slot award between 10 to 50,000 x your line bet. So the payout range the Playtech slot offers is extensive to say the least. Wilds deliver the biggest returns, followed by scatters and crystal symbols.

The top paying symbols in Jackpot Giant (after the wild and scatters) are the coloured crystals, with pink being the most valuable at 500 coins for 5, followed by blue (300) then amber (200).

However, alongside these regular reel symbols Jackpot Giant also uses two unique stacked symbols, which piggyback across two positions on the reels. One is the giant and the other is volcano, the other the giant in the jungle. When either of these crop up rub your hands together because some nice payouts are about to come your way.

The Jackpot Giant slot machine takes full advantage of the online video slot platform with a bonus game that temporarily takes players away from the main slot action. Landing the bonus symbol on reels 1 and 5 unlocks this feature. When this occurs the giant will push the reels to the side, to reveal the bonus round.

There's nothing too taxing or complicated about bagging yourself a real money return in this mode. You simply see 6 volcanoes on the screen (each of which contains a hidden amount of cash) and your job is to select 3 of the 6 at random. The giant then tosses a coin into your chosen volcano's mouth, at which point it will erupt with riches revealing the amount of money you've won.

At the end of the bonus round, the three remaining volcanoes will display their cash balance. Players then discover if they correctly identified the most money or missed out on the chance to take home a bigger payout.

Of course the Jackpot Giant slot machine is a progressive game, so it's landing this top prize that can really turn your fortunes around. To do this you'll need to bet the top amount with every spin, which in Jackpot Giant is just £4.

The progressive jackpot payout is triggered when you line-up 5 wild symbols on payline #1, which is a horizontal line that cuts straight through the centre of the reels. Do this, and that top prize is yours for the taking. Note that if you land this combination while betting any stake less than £4, you'll only qualify for a payout of 50,000 times your line bet. It's not an unimpressive take home, but still a great deal less than securing the £4 million + progressive jackpot this Playtech powered slot will reward.

It's not often we have the pleasure of playing a slot game that doesn't hold back its biggest rewards for the players forking out the highest line wagers, but that's the charm of the Jackpot Giant slot from Playtech. The betting range here doesn't alienate low rollers. If you've got limited funds to gamble with, but big aspirations of landing a life changing win, this is the slot for you.

We were also impressed to find that the Jackpot Giant online slot is just as compatible with smartphones and tablets as it is desktop. Android and iPhone users can enjoy the top-level gaming action and cash prizes on offer just as much as those signing in to play from Mac or PC. Top marks all round from our team.
