Riddle Reels: A Case of Riches

Riddle Reels: A Case of Riches by Play’n GO is a 3-reel video slot laid out with a classic UK pub-style fruit machine feel, set on a 3×3 grid with 9 fixed paylines. The theme revolves around detective mystery, inspired heavily by Sherlock Holmes and the ambience of Victorian London, with suspects, weapons, and intrigue making up the symbol set. There are three types of Wilds: a standard Wild, a x2 multiplier Wild, and a x3 multiplier Wild. Wilds substitute for regular symbols (excluding scatters), and if more than one multiplier Wild contributes to a win, their multipliers combine. A special Scatter symbol appears as a magnifying-glass: landing 2 Scatters triggers a respin, locking in the scatter reels while the remaining reel spins again in hope of a third scatter. If the third Scatter fails to land, the Mystery feature activates: the two locked Scatters duplicate to cover their reels and then transform into matching regular symbols. If three Scatters land (either directly or via respin), the Case of Riches bonus begins. In Case of Riches, a board of 14 clue spaces wraps around the reels; you roll a die four times and move through the board collecting Clue Points by completing mini-challenges tied to those spaces. Each clue space offers between 1 and 3 free spins plus one of four spin variations such as converting all weapon symbols to one weapon, converting suspects, guaranteeing a wild reel, or having no modifier. Filling the Clue Points meter fully during the bonus grants a Mega Spin—a single free spin where one reel is fully Wild or Multiplier Wild, and the others are suspect or weapon symbols. If the meter isn’t filled after the four moves, a Clue Points Wheel gives another chance to win the Mega Spin. The Bonus can retrigger after the Mega Spin if conditions are met.
