Riddle Reels Slot Review

Riddle Reels: A Case of Riches is a three-reel slot based on the theme of one of fiction’s most famous characters, Sherlock Holmes. The game is a reimagining the traditional UK pub fruit machine game, updating a classic format.

The HP symbols of the game are based on prominent characters from Sherlock Holmes lore; Irene Adler, Charles Augustus Milverton, Eugenia Ronder and, of course, Professor Moriarty. The LP symbols are a gun, a knife, a wrench and a rope.

The game has three Wilds, all featuring the dynamic duo of Holmes and Watson; a standard Wild, a x2 multiplier Wild and a x3 multiplier Wild. Each of these Wilds can substitute for any HP or LP symbol to create winning lines, and the multiplier Wilds will increase any wins they make up. If more than one multiplier Wild forms part of a winning combination then the win will be multiplied by the product of those two Wilds (i.e. a x2 and a x3 multiplier on one winning line give a x6 multiplier)

The last symbol is the game’s Scatter which can unlock a variety of bonus features.

The slot has plenty of base game action and plenty of extra features to keep players engaged throughout their session.


Landing 2 Scatters on any reel will trigger a re-spin. The reels containing the Scatters will be held, and the final reel will re-spin.

If a Scatter doesn’t land on the re-spin, this will trigger the “Mystery” feature. If a Scatter does land on the re-spin, it will trigger the “Case of Riches” bonus feature.


After a re-spin, if a third Scatter doesn’t land on the reels, this feature will be triggered and the two Scatter symbols will duplicate on their respective reels. They will all then be transformed into another symbol and pay out any wins.

Case of Riches

Trigger this feature by landing three Scatters across the reels during the base game, or as part of a re-spin.

Case of Riches is made up of five parts:

  1. Objective
  2. Starting the case
  3. The board and the challenges
  4. Solving the case
  5. Second Chance wheel


The objective of the game is to collect the clues and solve a case alongside Sherlock Holmes!

Starting the Case

To solve the case, players must fill the clue points meter and are giving four moves in an attempt to do so.

At the start of each move, the player will roll a die and Sherlock will make his way around the board, landing on different Free Spin Challenges.

The Board and the Challenges

The board displays around the reels and consists of 14 squares, including the starting space. Each space consists of a challenge. The challenge will be played out on the reels in the centre of the board and will often contain reel modifiers. Completing the challenge will award Clue Points and fill the Clue Points Meter.

Solving the Case

After the four moves have finished, the player may have collected enough Clue Points to solve the case! If this has occurred, then the player will be awarded a Mega Spin.

Mega Spin

On the Mega Spin, the Mystery feature will be triggered on two reels and six identical symbols will be revealed on those reels. The third reel will be filled with Wilds (they may be Multiplier wilds).

After the Mega Spin, the bonus feature will re-trigger, and players will be asked to solve another case.

Second Chance Wheel

After the four moves are completed, the player may not have collected enough Clue Points to solve the case. If this has occurred, then the player will be awarded the Clue Points Wheel.

The Clue Points Wheel will give the player an extra attempt at solving the case by spinning a wheel. If the wheel stops in the win segment, they will solve the case, if not, then the case is lost, and the bonus will end.

The size of the win segment in the Clue Wheel will be directly affected by the number of Clue Points collected along the way. If a player wins the case through the Clue Points Wheel, they’ll be asked to solve another case.
