Riddle Reels: a Case of Riches (Play’n GO) slot review

riddle-reels-play-n-go logo

A Sherlock Holmes lookalike is starring in this slot. Yes, of course, it’s a lookalike as Play’n GO does not have the right to use his name. But, I guess the lambswool raincoat and cap look too familiar! The idea remains the same. If you can solve several clues (clues), you can land a massive win!

Riddle Reels: a Case of Riches – solve the mystery in this Play’n GO slot

After Netent’s excellent Cash Noire release, Play’n GO couldn’t sit back. They also responded with a detective slot, Riddle Reels.

The top win is 5,000x the bet

That’s the default max win for most Play’n GO slots these days. It’s not dizzyingly high anymore, but of course still an excellent win!

Software: Play’n GO

Number of paylines: 3 reels with 3 rows, 9 fixed paylines

RTP and variance: 96.22%, Medium variance

Maximum win: 5,000 x the bet  or  $€0.5 million

Betting range: $€0.10 – $€100

Bonus features: Mystery Feature, Bonus Feature

Casino Hipster verdict: Hot!


Riddle Reels slot – Gameplay and Features

Riddle Reels has 3 reels with 3 rows of symbols and 9 fixed paylines.

The premium symbols are four suspects. You have:

  • A man with a hat on a blue background (3-of-a-kind yields 12x)
  • A blonde with velvet gloves on a golden yellow background (3-of-a-kind yields 8x)
  • An older man in green with sunglasses (3-of-a-kind yields 4x)
  • An older woman with a purple outfit (3-of-a-kind yields 2x)

The lower symbols are four murder weapons: a Pistol, a Sword, a Hammer and a Hangman Rope (noose).

You have three types of Wilds: a regular Wild, a x2 Wild and a x3 Wild.

3-or-kind of the regular Wilds gets you a win of 12x, but of the x2 Wilds, the win is 96x, and of the x3 Wilds, it’s a fantastic 324x.

The Scatter symbol is a Magnifying glass with a red question mark.


The Mystery Feature

The main game is enriched with the Mystery Feature.

If you spin 2 Scatters, you get a free respin. It gets you a second chance to land the 3rd Scatter (which activates the Bonus Feature).

If you fail to land the 3rd Scatter, the two reels where the first 2 Scatters appeared, get 6 identical symbols.

If you’re lucky, you’ll have identical symbols (or wilds, with possible multipliers) on the other reel. In the best case, you have three wilds with x3 multipliers and 6 “blue” suspects. Then you bag a win of 324x (9x12x3=324).

The Bonus Feature – now, you can finally solve the mystery.

You activate the Bonus Feature by spinning 3 Scatters. Now the fun begins. You have to solve the mystery and find out who the murderer is and what weapon is used.

Around the three reels, you’ll see a gameboard. You get four throws with a die. Besides, you get clues which you need to solve. If you do so correctly, you get extra free spins and additional advantages (e.g. symbols with all the same weapons or the same suspects), which increases your odds of making winning combos.

In the end, you’ll see how many clues you’ve solved. The level of difficulty also matters.

If you’ve solved everything successfully, you’ll get a Mega Spin to finish off. Now it’s announced who the suspect is OR what weapon the suspect has used. Often the Mega Spin guarantees a massive win, especially if there are Wilds with multipliers involved.

By the way, if you’ve solved almost all (but not all) clues correctly, you’ll still get chances to win the Mega Spin. You get to whirl the Clue Points Wheel (a blue compass). Your odds depend on how many clues you’ve solved.

Payout percentage (RTP)

The default RTP of Riddle Reels is 96.22%. However, there are versions with a lower RTP in circulation. Before playing, I recommend you to check the Riddle Reels game rules.

The variance of Riddle Reels is medium

Play’n GO gives a score of 5 out of 10 for the variance. In other words, the variance is medium.

I expect that most top wins are around 500x the bet. A full screen with the x3 wilds and the highest symbol is good for 324x.

Other popular Play’n GO slots games with medium volatility are: Twisted Sister, Win-A-Beest and GEMiX.
