The background of this slot appears to be an old fashioned-style hut interior complete with a stone floor, and latticed windows. Candles light the room filled with wooden workbenches, bookcases and drawers as other renaissance items like large scrolls and chests littler the background. The grid itself is bordered by a beautifully carved, gold frame above which the games title in polished gold and silver completes the scene.
The grid itself is made up of 6-reels and 4-rows as standard, however the number of rows can vary between 3 and 7 because of the different sized symbols available. The lower value symbols are made up of the 9 – A Royals that appear in various colours and regal writing, higher valued gems of yellow, green, blue also appear offering up to 25x the stake for 6 in a row. There is also a Wild symbol that can appear on the top reel that will substitute for other main game symbols to create valuable winning combinations.
The ‘Payways’ game mechanic, much like Big Time Gaming’s ‘Megaways’ is used to offer varying paylines during play, however it is not quite a simple. In Perfect Gems the 1st and 6th reel stay fixed with 3 reels, whilst the middle-reels are able to expand to 4 symbols however the horizontal reel can expand these to 7 symbols if a symbol in that reel is identical to one below. As mentioned earlier this can result in over 21,000 ways to land a winning combination.
The Win Multiplier to the top-left of the grid is another feature involved here, it will increase by 1 with every consecutive win by the cascading symbols feature. This mean when a winning combination is made the symbols are removed and replaced with new ones from above, if another win is achieved this will reoccur. The multiplier will continue increasing infinitely until a winning combination is not made.
Free spins in Perfect Gems can be activated by landing 3, 4, 5 or 6 Scatter symbols, players can receive 9, 15, 21 or 27 spins respectively. During these spins the Scatters are replaced by Spin Scatters of which each one will add an extra 2 spins to the count, better yet the free spins feature can be retriggered infinitely. The Win multiplier also carries over into free spins, the multiplier will only ever increase.
