Play’n GO has been responsible for some of the most successful video slots in history; titles like Moon Princess, Reactoonz and Book of Dead spring to mind. Next to enter their ever-growing portfolio of games is their Riddle Reels: A Case of Riches slot which offers players the chance of winning up to 5,000X their stake and comes with a number of exciting bonuses and features including a “board collection” feature, something we’ve seen used successfully in other video slots like NetEnt’s Jumanji slot.

Riddle Reels: A Case of Riches comes with an RTP of 96.22%. However, Play’n GO generally releases all of their slots with a sliding RTP scale, so some online casinos may choose to offer a lower RTP version. The game can be played from between 10p and £100 per spin, and it’s built around a 3X3 grid format with just 9 fixed paylines in play. In this Riddle Reels: A Case of Riches review we’re going to be taking an in-depth look at the game, kicking things off with a look at the slot’s theme, design and layout.

Riddle Reels A Case of Riches Slot Theme, Design, and Layout

It’s pretty clear that Play’n GO have chosen to build Riddle Reels: A Case of Riches around a Sherlock Holmes theme – and while there are no specific references to him during gameplay, you don’t need to be a detective yourself to figure out he’s the main inspiration behind the slot. 

As the player, you’ll be tasked with investigating various criminals of the underworld, solving clues to try and uncover vast rewards and prizes. As with virtually all of the developer’s slots, Riddle Reels: A Case of Riches offers up impeccable graphics, and the gameplay is incredibly smooth.

If you’re playing from a desktop device, you’ll see Play’n GO’s signature bet selection option right at the bottom of the screen. This shows you a number of different bet options right off the bat, and there’s also some game options available including autoplay and fast spins. If you’d like to learn more about Riddle Reels: A Case of Riches slot, you can also access a detailed pay table which shows you the game’s payouts, along with a very detailed rules page.

Riddle Reels: A Case of Riches has a total of eight paying symbols, and these include both the lower-paying and higher-paying symbols. The lower-paying ones include four weapons; a noose, a tool, a dagger and a pistol. These don’t pay a whole lot, offering between 0.4X and 1X your stake for a 3-of-a-kind combo.

The game’s higher-paying symbols are all various criminal suspects, including a purple-dressed woman, a green-glassed man, a golden damsel and a scary-looking man; the game’s main protagonist.

Special Symbols, Bonus Features, and Gameplay

Aside from the main bonus round, which we’ll cover below, Riddle Reels: A Case of Riches slot also offers multiplier wilds. Wilds can have a 2X or 3X multiplier attached to them, and the multipliers multiply against one another. This means that if you’re lucky enough to land three of the 3X wilds, that win would be multiplied by a total of 27X!

Riddle Reels: A Case of Riches Slot Bonus Features

Riddle Reels: A Case of Riches is packed with features, and the main bonus round is triggered by landing three of the scatter symbols anywhere in view. However, if you land just two of them you’ll trigger a re-spin feature; the two reels that contain the scatter symbols are locked in place while the remaining reel re-spins. It’s essentially giving you a second chance of hitting the main bonus, although if a third scatter doesn’t land you do trigger the “Mystery Feature” which sees each scatter symbol duplicating before all revealing identical symbols.

If you’re lucky enough to trigger the main Free Spins bonus you’ll be taken to a board game type of feature. This board has a total of 14 spaces, and each space contains a different clue. You get to roll a pair of dice four times, and each time you land on a clue you’re awarded between one and three free-spins. You will also receive one of four free-spins “perks” when they begin. First, you’ve got the weapon free-spins which converts all weapon symbols to the same weapon on every spin. Next up is the Suspect free-spins, during which all suspect symbols transform into the same suspect symbol on every spin.

Third is the guaranteed wild reel free-spins; one reel is wild on every spin, and finally there’s the “nothing” option; this means there are no enhancements during the free-spins and they’re just regular spins.


Riddle Reels: A Case of Riches slot is an interesting concept; in today’s fast-paced online gambling market 3X3 slots don’t do too well, but Play’n GO appears to have made Riddle Reels: A Case of Riches work. It’s fun-to-play and with up to 5,000X your stake to be won there’s plenty of win-potential to look out for too!
