40 paylines (player-selectable 1-40)
Genii rarely commits to a mature aesthetic this fully. Traces of Evidence drops you on a wet asphalt street at 2am, red and blue cruiser lights washing the reels, a hooded detective silhouette planted in the foreground. The bold yellow “POLICE LINE DO NOT CROSS” tape arcs across the top, holding the title in heavy black sans-serif. It's a committed gritty look that earns its CSI badge, and the photorealistic symbol art (bullet casings, a bloody pistol on concrete, a corpse's morgue-tagged feet, a “FACE MATCH” database mugshot) sells the mood without tipping into shock value.
The card-rank treatment deserves its own paragraph. J, Q and K aren't generic playing cards. They're forensic petri dishes filled with letter-shaped smears of coloured biohazard residue, red, pink and green. It's a small detail. And it's exactly the kind of theme integration most mid-tier studios skip. Underneath that creativity sits a standard 5×3 grid with 40 paylines, player-adjustable down to one if you want, and a bet range from $0.01 to $50 per spin.
RTP lands at 96%, which is fine, neither generous nor stingy. Volatility isn't officially published, but the mechanic reads as medium: a Wild that pays its own combo at 3,000 coins for five-of-a-kind, an Autopsy bonus that drip-feeds cash, and standard Free Spins without any multiplier attached. That last bit's a quiet disappointment, honestly. Most Genii titles double or triple in FS, so seeing base-game payouts carry straight through feels conservative.
Three scatters do different jobs. One triggers Free Spins (8, 15 or 20 spins for 3, 4 or 5 scatters, retriggerable). One triggers the Autopsy Feature, a step-through forensic mini-game where you click crime-scene photos and collect instant cash, and it can fire during Free Spins too, which is unusual for the studio. The third is a plain paying scatter dropping 2, 8 or 20 coins times total bet.
No buy-bonus, no jackpot, no ante. Just a serious procedural drama in slot form, with one genuinely clever theme flourish and a Free Spins round that could've used more punch.
