Riddle Reels: A Case of Riches is a three-reel slot from Play'n GO with nine paylines and medium volatility. The base game includes standard Wilds, x2 Multiplier Wilds and x3 Multiplier Wilds, each able to substitute for regular symbols and increase wins when part of a combination. If more than one multiplier Wild lands on the same line, the multipliers are combined.
Scatter symbols unlock the main features. Two Scatters trigger a re-spin, holding the Scatter reels in place while the remaining reel spins again. If a third Scatter does not appear, the Mystery feature duplicates the Scatters and transforms them into another symbol to create a payout. When a third Scatter lands, the Case of Riches bonus round begins.
In the bonus game, players follow Sherlock Holmes across a board of 14 squares, complete challenges and collect Clue Points over four moves. Reaching the required total awards a Mega Spin, while failing to do so activates the Second Chance Wheel for one more attempt. This demo version is available to play for free and offers a way to practice before playing for real money.
