Genii's Whodunit? is a cheerful raid on Hasbro's Cluedo, dressed up as a Victorian parlour mystery and committed enough to the bit that you'll either grin or roll your eyes. The reels sit framed inside a wood-panelled study, leather wingback chair off to one side, chandelier gleaming overhead, tall arched bookcases stuffed with leather-bound classics. It's a 5×3 grid running on 40 paylines, lines pay left to right, and the volatility plays high. So expect dry spells punctuated by satisfying spikes rather than the steady drip of constant small wins.
The character lineup leans hard into the Cluedo wink. There's a Lady in Red sipping a martini behind an opera fan, a stern Female Chef in pristine whites, and a Reverend in a green cassock. Their weapons sit one tier lower in the paytable: a golden art-deco pistol, a rolling pin, a wine glass paired with a skull-labelled poison bottle, and a silver crucifix. Card royals (A, K, Q, J) round out the bottom, rendered in flat block colour that matches each cell's pastel background. It's a nice touch.
Top symbol pays 1,500 coins for five of a kind. Wilds substitute for everything except the two scatters, and the headline number from the paytable is 17,340 coins as a maximum. Bet range runs $0.01 to $50.00, so it scales fine for cautious players and high-rollers alike.
Two scatters drive the bonuses. The magnifying-glass Free Spins scatter awards 8, 12, or 15 spins for three, four, or five symbols anywhere on the reels, and every win during the round is doubled. Retriggers are possible. The purple Feature scatter triggers the Whodunit bonus game, a Cluedo-style room-pick where you tap rooms in the manor floor plan and each one reveals a random prize scaled to your triggering bet. The Feature can't fire during Free Spins, which is a shame, because layering them would've been the obvious move.
Genii doesn't officially publish RTP here, and that's worth knowing before you commit serious money. But for a themed mid-range slot with two distinct bonus modes and a paytable that goes 12 symbols deep, Whodunit? punches above its weight. It's not a sleek modern release, but the personality carries it.
