Electric Elephant gives brings players a classic 243 Ways to Win slots experience, with a couple of interesting twists in its Sherlock Bones slot. The Rolling Respins feature in this game triggers walking wilds and expanding reels, and there’s no set limit to how many respins you can receive in this medium variance slot game.

Theme and Graphics

Sherlock Bones is a quirky twist on the tales of Sherlock Holmes, starring a – you guessed it – a canine detective. The character symbols are great, as Watson is a cute weiner dog wearing a bowler hat and the villain in this tale is a very mischievous-looking cat who is wearing a monocle and appears to be scheming up some trouble. The main character, Sherlock Bones, is wearing the signature deerstalker cap while holding up a magnifying glass and smoking a pipe.

The game takes place in a cloudy, dreary London and there is a bit of a steampunk twist to the aesthetic. It also has a great soundtrack – perfect for a mystery-themed game

Sherlock Bones RTP and Variance

The RTP (return to player) of Sherlock Bones is 96.21%. It’s also a medium variance slot – which you don’t see very often nowadays, as most new releases tend to be very highly volatile.

How to Win

Sherlock Bones takes place on a 243 Ways to Win grid, with winning combinations being made when three or more matching symbols land on adjacent reels. The sneaky cat character is the highest-paying symbol, awarding a prize of 10x for a five-of-a-kind combination. Sherlock himself is the game’s wild, and he can expand to help you land wins more easily.

Rolling Respins

Along the bottom of the reels, there is a conveyor belt. Whenever an expanding wild appears on the reels, the conveyor belt will spring into action. Should bone a bone symbol appear on the conveyor belt on the same reel as the wild, you’ll trigger the Rolling Respins bonus.

During this bonus, the expanded wild will turn into a walking wild. Whenever you hit a win, the wild will walk to the left and an additional row of symbols will be added to the game. Up to 4 rows can be added, and more walking wilds will be added to the game if another expanding wild coincides with a bone symbol.

The Rolling Respins bonus in Sherlock Bones only ends when all wilds have walked off of the reels.  

Sherlock Bones Slot Review

Sherlock Bones from the games developer Electric Elephant is a fun online slot with a well thought-out theme, but we wish the gameplay were as considered. As a medium volatility slot, Sherlock Bones keeps you entertained – but only because wins come around more frequently than in high variance slots. There’s no real base game feature, which can make things seem a bit repetitive.

The game’s saving grace is the Rolling Respins bonus – which is actually more of a free spins round. You not only get to expand the reels but also having having walking wilds, and there’s no predetermined number of spins. So, this bonus can last quite a while.

However, it’s very difficult to land this feature. The expanding wilds don’t really come around all that often during the free spins bonus and it’s even rarer for them to coincide with the bone symbols in order to trigger the bonus game.

All in all, Sherlock Bones is a game that is ideal for patient players. There is some great payoff in the bonus round, but it takes a while to get to it – and the journey there can be a schlep.
