Holmes and the Stolen Stones

The Brothers' take on Holmes and the Stolen Stones

Holmes and the Stolen Stones is Yggdrasil's Sherlock-Holmes detective slot with five tiered progressive jackpots running underneath. It's been quietly paying out since 2015 and the maths still holds up.

Five reels, 20 paylines, Victorian London visuals with Holmes, Watson, magnifying glasses, and gemstone symbols. The base game pays through standard wins; the bonus side comes in two paths. The standard free-spins round (5 free spins on three or more scatters, with up to 10 awarded for higher scatter counts) layers a Pick-Me cash bonus on top. The major draw is the five tiered progressive jackpots — Mini, Minor, Major, Mega, and Grand — fed by 3.4% of every bet across the network. Average drop levels run from €108 (Mini) up to €30,000 (Grand), with the Grand seeded at €10,000.

Default RTP is 96.8% (some sources cite 96.28% as the operator-shipped variant). Volatility is medium, which is unusual for a progressive-jackpot slot — most jackpot games run at maximum volatility because you're paying the jackpot tax through the rest of the maths. Max non-jackpot win is around 12,000× the stake; including the progressives, the ceiling reaches 30,000× for the Grand. Bet range runs from 20¢ to €/$40.

The Brothers don't usually chase progressive jackpots — the maths almost always favours non-progressive slots for steady returns — but Holmes is the rare exception. The medium volatility means you can sit with it for hours without burning through a bankroll, the standard free-spins trigger pays well enough to cover sessions, and the progressive is a genuine background lottery with five different drop levels. It's a slot you can play casually while letting the jackpots be a long shot.
