Land a win made up of a high value symbol and it is upgraded and will pay double next time if makes up part of a winner. Land a low value symbol win and that symbol is removed from the reels for the rest of the round.

Cauldron Slot RTP, Details & Wager Limits

The action in the Cauldron slot plays out on a classic 5 reel, 3 row, 20 payline machine. Winning combinations are formed by land 3 or more matching symbols or wilds from left to right on a payline, starting from reel 1 on the left.

You can try and bubble up a jackpot at stake levels that range from between 20p and £100 per spin. Click on the bet icon then choose from the options shown. The paytable show amounts in cash rather than coins and is amended as you alter your bet size. It’s all very straightforward to follow.

The Cauldron RTP is 96.04% which is about average. The hit frequency rate is 20.29% so you can expect to land a winning combination on around one fifth of spins on average.  The gameplay here is simple enough but Cauldron can still deliver a decent payout punch. The volatility here is high. The most you can win from a single spin is 2,222 x your total stake.

Theme – Audio & Design Features – join the blue wizard in the deep caves of Algroth 


Like the other slots in the Peter & John catalogue, the design in the Cauldron slot is very impressive. There’s a fresh, modern feel to the rather creepy visuals. With a magic/wizard theme, you head to the deep caves of Algroth. There’s a rather jaunty, fantasy-style soundtrack playing in the background while you spin that complements the visuals nicely.

At the bottom of the screen is a bubbling cauldron. At the top are the spindly fingers of a wizard. In between are the reels, where you’ll find 5 lower value plant-related symbols. These include a rotten apple, mouldy carrots, a toad stool, a Venus fly trap and a berry. They’re joined by 5 higher paying critter symbols. You’ll see bees, spiders, bats, frogs and mice. The mouse is the top standard symbol, paying 50 x stake of you land 5 on a payline.

There’s also a potion bottle scatter. This also pays 50 x stake if you land 5 on the same spin. Land 3 or more to trigger the feature.

Cauldron has been fully optimised for play on all devices including smartphones and tablets as well as desktop computers. The super sharp imagery and the simple gameplay are an excellent combination and make the Cauldron mobile slot a very straightforward one to play.

Cauldron Bonus Features

With 2 bonus features, free spins are central to most of the best action on offer in the Cauldron slot. They come with some pretty tasty extras too in the form of symbol upgrades and the removal of low value symbols. There are more goodies on offer when you trigger the Super Free Spins too.

Free Spins feature


Land 3 potion bottle scatter symbols on the same spin to trigger the Free Spins feature. You’ll then go on to play 10 free spins. Land 1 of the higher value critter symbols in a winning combination during the feature and that symbol gets upgraded and 1 extra free spin is added to your total.

If you subsequently land a winner made up of an upgraded symbol, its payout value is doubled. You can upgrade each higher value symbol once.

There are also extra free spins on offer when you land a winner made up of a lower value symbol. Again, 1 extra free spin is added to your tally. That low value symbol is then removed from play for the rest of the feature.

Super Free Spins feature

Each time a potion bottle scatter symbol lands it’s collected in a meter alongside the reels. When you have collected 750 potion bottles, you’ll activate the Super Free Spins feature.

Your reward is 10 free spins. These are played on a special set of reels where all the lower value symbols have been removed and all the higher value symbols have been upgraded and their value doubled.

Cauldron Review Summary – simple magical action

This tale of sorcery is a relatively simple one as far as gameplay is concerned. The Cauldron slot is all about free spins which can be well worth landing though thanks to the symbol upgrades and the double payouts. Remove the lower value symbols and add extra free spins early on and the action can fly.

The bigger wins of 2,222 x stake are more likely to come in the Super Free Spins feature as you’ll play with just higher value symbols. Be warned, though. This is a volatile slot so expect some lean spells too.

If you’ve enjoyed other Peter & Sons slots like Robin: Nottingham Raiders and Robin: Sherwood Marauders, expect similar fare in Cauldron.
