By the Reel Bulletin desk · Updated 5 Nov 2026

A detective in a fedora and dark trench coat holds up a gold magnifying glass swirling with purple smoke, a green-eyed black cat perched on his shoulder, while a glowing skyline sits behind him under a burst of light. The mode names suggest a case being pieced together on an investigation board. It went live on Stake in August 2026.
Three paid entries are available. Shadow Lock Respins is the cheapest at 35x, returning 95.52%. Investigation Board Free Spins costs 90x at 95.50%, and Enhanced Investigation costs 180x at 95.54%. The base game also sits at 95.50%, with every route capped at 5,000x. High volatility pairs that ceiling with uneven pacing, so long stretches of small or no returns are to be expected between the occasional strong hit.
