Batman and the Riddler Riches is powered by Playtech and has 5 reels and 243 ways to win. Playable on desktop, mobile and tablet devices from 25p to £60 per spin, it’s another of the DC Comics series slots that offers you 4 progressive jackpots. There’s a whole host of features too with Mystery Reels, Collapsing Reels and free spins galore.

Style wise, it benefits from comic book graphics and animations which represent the original television series from the 1960s. Symbols on the reels include the Riddler, Batman, Robin, statues, hat and gloves, Batman’s belt and police chief Clancy O’Hara. The Batman logo is the wild and substitutes for all symbols (except the scatter) and appears on all reels except reel 1.

Batman and the Riddler Riches benefits from the Collapsing Reels feature – when you get a winning combination, this triggers a collapse with any symbols in the winning combination disappearing. A second wave of new symbols appears giving you chance to win time and time again. The waves continue until you don’t get a winning combination.

You have also the Mystery Spins feature which is triggered randomly on any base game spin – you get to riddle your way to big wins as the Riddler can add mystery symbols which then transform into the same symbol to give you a winning combination.

Then you have the Batman vs The Riddler Bonus Wheel which is accessed when you get the bonus symbol on reels 1, 2 and 3 simultaneously. You get to spin the wheel to play 1 of 3 riddlerific features. There are as follows:

Sticky Wild Free Games feature – benefitting from 10 free spins, sticky wilds (either green, yellow or red) can land on any free spin and will remain sticky for up to wave 3 (that’s the 3rd consecutive winning spin by the way).

Multiplier Free Games feature – with 10 free spins awarded, all wave 2 wins are subject to a 2x multiplier whilst all wave 3 wins are subject to a 3x multiplier. If you’re lucky enough to get wave 4 or more wins, you will benefit from a 5x multiplier! When all waves have played out, the multiplier resets to 1x for the next free spin.

The Riddler Box Bonus feature – here you need to solve the riddle to win big cash prizes as you open the boxes to reveal cash prize values. If you match 3 cash values, you will that corresponding prize. You can also open 3 more boxes to match 3 multipliers which are applied to your winnings.

Like with the other Batman DC Comics games, there are 4 progressive jackpots to be won. You can randomly enter the DC Super Hero Jackpot Game where you are guaranteed to win the Mini, Minor, Major or Grand jackpot. You need to pick from 20 icons – match 3 to win that particular jackpot.

I think Batman and the Riddler Riches is my favourite of the Playtech DC Comics slots due to the range of bonus features on offer – I like the Collapsing Reels in the Multiplier Free Games feature as you can get a 5x multiplier on every free spin in essence (as well as 1x, 2x and 3x!).

I found it to be a medium variance slot which is nicely balanced offering good wins in the base game and various bonus features. I recommend you also try Batman and the Batgirl Bonanza which has an unusual reel layout and can give you up to 25 free spins with a 2×2 Super Wild Symbol!
