New Online Slots

The latest online slots to hit the casinos. These are new online slots that we have just reviewed:

New to play at William Hill Slots is Zhao Cai Jin Bao Jackpot Slot which means ‘we wish you wealth and success’. It’s a 5 reel 9 payline progressive jackpot slot that is linked to Playtech’s whopping Dragon Jackpot prize. Also new at William Hill Casino is Geisha Story Jackpot Slot which is a 5 reel 15 payline slot again linked to Playtech’s Dragon Mystery Progressive Jackpot.

New online slot MegaJackpots Wolf Run Slot a 5 reel and 40 payline slot from IGT Slots offers life-changing wins in its MegaJackpots Progressive – starting at £500,000 and escalating quickly. Also new is 88 Fortunes Slot a 5 reel slot with 243 Ways To Win from Bally Slots.

New at BGO Vegas Slots is the Space Invaders Slot from Playtech Slots who have done a very neat transformation of the Space Invaders game look and feel (including the classic sound effects which are a joy to hear again) into a very compelling slot.

New at MrGreen Slots is the heavy metal favourite Motorhead Slot (I know Lemmy said his style was Rock N’ Roll). This NetEnt Slots powered 5 reel and 76 payline video slot plays Motörhead Music as you spin the reels.

Bet365 Slots have a great new slot called Buffulo Blitz Slot which is a Playtech powered 6 reel and 4,096 Ways To win. This is a high volatility slot offering a fast paced slot game.
