Knight’s Keep is powered by WMS and has 6 reels and 192 paylines. Playable from 40p to £200 a spin across all devices, this medieval themed offering comes with symbols that are randomly replaced with another symbol before each spin. There’s also a Free Spins Bonus feature where up to 25 free spins can be won on a flipped reel set for bigger wins.

Visually, Knight’s Keep looks like the land-based slots they’ve released in the past which offers a real charm. With a medieval theme, you’ll see a castle under a moonlit backdrop. Symbols on the reels include spades, diamonds, clubs and hearts as well as sceptres, crowns, jesters, queens, kings and knights (which appear in WMS’ Black Knight II). The latter offers you 10 times your stake for 6 across a payline – the knight is the wild that replaces all symbols bar the scatter.

Using the Reel Boost game engine, reels 2 through 6 contain a number of adjacent positions which are randomly replaced with 1 of the above-mentioned symbols (bar the wild) before the start of each spin. This can lead to bigger wins due to stacked symbols appearing on the reels.

Knight’s Keep is all about the Free Spins feature which is played when you get 3 or more Bonus symbols on reels 2 through 6 – 3, 4 or 5 bonus scatters will give you 5, 12 or 25 free spins as well as 2, 10 or 50 times your stake respectively.

You will notice the reel set is flipped which allows for an increase chance to win bigger. During the feature, 3 to 4 reels will randomly change to 1 symbol on ever free spin with the 1st reel always changing – this again allows for bigger wins. Also, reels 1 to 5 will see 1 randomly chosen symbol appearing on every free spin. If you were to get a screen full of kings, you’d win an impressive 1,440 times your stake on every free spin!

Knight’s Keep is a medium to high variance title which is all about the Free Spins feature really – with good winning potential, it’s another good land-based slot that’s found its way online. I also recommend you try Zeus III which uses the same game engine but offers you stacked wilds.
