Shimmering gemstones can offer big rewards in Diamond Jackpots, a jewel-themed slot powered by Blueprint Gaming. Played using a 5 reel, win all ways game engine, there’s not much on offer in the way of extras here but fill the screen with diamonds and a bumper 10,000-coin jackpot can be won. Playable on all devices, stakes start at 10p, rising to £500 per spin.

The design in Diamond Jackpots is simply done – the reels are set against a silky blue backdrop that’s covered with stars. Joining the lower value A to 10 playing cards are 4 different gemstone symbols.

The least rewarding of these is the green gem – this pays 20, 50 or 200 coins if you land 3, 4 or 5 in combination. The blue stone follows. This pays 50, 80 and 400 coins. Land 3, 4 or 5 of the red jewel and the payouts increase to 70, 100 and 500 coins. The most lucrative symbol is the shimmering white diamond – this offers awards of 100, 200 or 1,000 coins. Winning lines can be started from reels 2 and 3 and well as the standard reel 1.

All symbols can land fully stacked too – that becomes especially important in the case of the top paying white diamond. Fill all 5 reels with stacked diamonds and you’ll trigger the jackpot and with it, a 10,000-coin payout.

That’s not the only jackpot on offer either – this slot is part of the Diamond Kind jackpot network which offers some potentially massive awards if it hits.

That’s about it as far as features go. There’s precious little to get excited about here. There are no free spins or pick me rounds. In fact, there isn’t even a wild. If you like slots with plenty of added extras, then look way now.

Diamond Jackpots is a super simple game. The design has a glossy finish which is what you’d expect given the gemstones theme. We found the gameplay to be a disappointment though.

The potential 10,000-coin bonus is a nice tempter but the lack of any extras left us underwhelmed. A slot based on shiny jewels should be anything but dull but that’s what we found Diamond Jackpots to be. I would much rather play other Jackpot King slots with Worms Reloaded and The Pig Wizard recommended.
