Riddle Reels: A Case of Riches

The game plays on a compact 3×3 grid with 9 fixed paylines, so every spin is easy to read. Wins are paid left to right across the usual line pattern. The low symbols are four weapons — rope, wrench, knife and revolver — with three-of-a-kind returns from 0.4x to 1x stake. Four suspect portraits sit above them and pay 2x to 12x for a full line. Wild symbols are the only base-game spark: standard wilds substitute for regular symbols, while x2 and x3 wilds multiply wins they complete. More than one multiplier wild on a line multiplies together. Three x3 wilds can push a single line to 324x, which is the one base-game result that feels properly sharp.

Three scatters trigger Case of Riches either directly in the base game or through the respin path. This is the primary mechanic, and it is busier than the reel set suggests. The bonus moves to a board wrapped around the reels. Sherlock gets four dice rolls, landing on clue spaces that start short free-spin challenges. The aim is to fill the Clue Points Meter before those four moves run out. Each challenge can involve weapon conversion, suspect conversion, a guaranteed wild reel or no modifier at all. Finish enough win-spin tasks and the case is solved, leading to the Mega Spin. Miss the target and the game offers a Clue Points Wheel, where the size of the win zone depends on how much of the meter you filled.

This is not a clean four-scatter, ten-spin bonus. Free spins sit inside the board game as challenges, usually one to three spins at a time. A clue may ask for 1, 2 or 4 winning spins to complete it, which is a clever way to make a small grid feel task-based rather than passive. The modifiers matter more than raw spin count. A weapon challenge changes all weapon symbols into one weapon, a suspect challenge does the same for suspects, and a wild-reel challenge guarantees a full wild reel. When the case is solved, the Mega Spin lands with the Mystery effect on two reels and wilds on the third. After that Mega Spin, the Case of Riches sequence starts again.

Two scatters trigger a respin, locking the scatter reels and spinning the remaining reel once. Land the third scatter and the board bonus starts. Miss it and the Mystery feature takes over instead. The two scatters duplicate to fill their own reels, then transform into matching regular symbols before wins are paid. It is a neat consolation prize because it can turn a dead two-scatter tease into a real line hit. It is not enough to rescue long cold stretches, but at least the tease has a purpose.

The international stake table runs from 0.10 to 100 credits; using late-May 2026 exchange rates, that is roughly CA$0.16 to CA$160 as a Canadian reference range. There is no Ante Bet and no Bonus Buy, which is the right call for this design. Ontario players can find Play'n GO content through AGCO/iGaming Ontario-regulated operators, but the exact title and RTP build still depend on the casino. Alberta is next: Play'n GO has an AGLC supplier licence ahead of the province's July 13, 2026 regulated-market launch.
