Illuminous Gameplay and Bonus Features
There are six card symbols in this game, which is plenty, and they can only pay 1x or 2x your bet at best. Furthermore, of the four medium win symbols two are not that good as they pay only 1.50x for four-of-a-kind and 3.75x for five-of-a-kind, and the only symbol that stands out is the Purple Diamond, that pays a 12.50x prize when you land five of them on a winning payline. Wild pays the same, and so does the Bonus Scatter, so you got three symbols that can pay a good prize, though Purple Diamond is the only one that can also be involved in a multi-payline win.
Bonus Wild Scatter symbol is an interesting one as it acts as both a Wild and a Scatter, so it substitutes for all symbols as well as being responsible for triggering not only the free spins game but also the re-spins. When you land three or more Scatters on a single spin, you'll enter the Hot Reel Free Spins, and if you land two Scatters you'll get a Hot Reel Respin. The two triggering reels will have additional Wilds, and if you happen to land another Scatter you'll get another re-spin.
When you land three or more Scatters you'll get 5 free spins and they'll also have the Hot Reel Effect so the three triggering reels will have more Wilds throughout the duration of the feature. If you land another Scatter during the free spins game, you'll get a Hot Reel Respin.
The game doesn't pay often during the main game, so it's one of those slots that need the bonus feature in order to loosen up and start paying. The higher chance of Wilds during the Hot Reel Respin and especially the Hot Reel Free Spins will have a serious effect, however, as not only the chance of Wilds will increase but you will actually get them. This will finally open up the game and make it pay multiple winning paylines, but chances are, your balance will already be negative and you'll need those bonus features to get back on track.
