Dark detective noir wraps around the reels — Sherlock vibes throughout. Board-game squares frame everything with detective kit symbols (ropes, wrenches, knives, guns). Three reels stay simple while the board creates depth. The investigative narrative hammers through every animation and symbol. Mobile screens pop without losing that mystery atmosphere! UK players get clarity on paytables despite the atmospheric design.
Fire up the demo through your desktop or mobile link. The three-reel interface sits front and center. Hit spin and watch for scatters crashing down. Two scatters trigger the re-spin feature. Three scatters? That’s your golden ticket to Case of Riches!
Playing cards combine with detective elements across the reels. Three Wild types fire up the premium action: standard Wild zaps substitutions, x2 multiplier Wild doubles wins, x3 multiplier Wild triples them. Scatters crash triggers and kick off features. Stack two x3 Wilds and watch your win cascade multiply. UK players see clear symbol values before spinning real money.
This game packs layers that go big or go big. Re-spin crashes when two scatters land — they freeze while the remaining reel spins again. Mystery feature wobbles in when re-spin fails — duplicates scatters and transforms them into something else! Case of Riches bonus — that’s the frenzy. Fourteen-square board with dice rolls, Free Spin Challenges that hum with Clue Points, Mega Spin that erupts with Mystery on two reels plus a third packed with Wilds, and a Second Chance Wheel when you need one more shot. Features chain into each other creating a hot streak machine.

Official RTP figures stay locked behind operator doors. Three reels stacked with multiple features suggest moderate-to-high volatility — perfect for players chasing hot streaks! Multiplier Wilds and Case of Riches build massive win potential. UK players should check current RTP through licensed operators before going real money. Demo play lets you crash through mechanics risk-free and spot the win frequency yourself.
Three reels fire standard winning line logic. The RNG zaps every spin — unpredictable and fair. Scatters control progression: two burst the re-spin; three unlock the Case of Riches ecosystem. No tilt traps here — just pure mechanical chaos.
Standard and multiplier Wilds pop into action substituting everything except Scatters. Here’s the crash — stack a x2 and x3 multiplier Wild on one win and watch them multiply together. That’s x6 multiplier roaring down the payline! UK players love this stacking potential.
Re-spin locks Scatter reels and spins the remaining one. Mystery feature wobbles in when re-spin fails — duplicates Scatters on their reels, transforms them into something else, and pays whatever lands. Secondary win opportunities explode everywhere!
Case of Riches packs the punch — fourteen-square board with Sherlock rolling the dice. Four moves guaranteed! Complete Free Spin Challenges and hum up those Clue Points. Mega Spin erupts with Mystery on two reels showing six identical symbols plus a third reel bursting with Wilds — bonus re-triggers if Clue Points surge enough. Fail to hit the target? Second Chance Wheel pops once. One more shot to go big or go home!
