It offers five reels with nine paylines as well as a free spins bonus round which awards 18 free spins with a 1-5x multiplier.The five reel, 25 payline Isis takes its inspiration from Ancient Egypt and includes icons such as bejewelled brooches and adorned amulets. Features include the wild symbol, Isis, and the scatter symbol, Horus, which triggers the bonus round. Up to 30 free spins and a 6x multiplier are on offer courtesy of the free spins feature.“Following on from our aggressive mobile strategy in 2013, we are continuing our rapid rollout of HTML5 games this year,” said Neill Whyte, Head of Product Channels at Microgaming. “However it’s not just about quantity, the quality is also paramount, and we aim to deliver the highest calibre of content to mobile players.
