An out-of-focus cityscape is in view behind a 5x4 grid of colorful, cartoon symbols. High card emblems in black and yellow crime scene tape, guns, and explosives appear alongside a crook and the detective in the base games. Trigger free spins and up to four Big Bosses can join the action.

It’s a desktop and mobile slot from Northern Lights Gaming. We’ve done the detective work and found the best Microgaming online casinos where you can play the Unusual Suspects slot machine along with the rest of their range.

Pick from a bet range of 0.20 to 500.00 per spin and you are ready to crack the case. 20 paylines cross the five reels and here’s how much symbols pay as a portion of your bet –

The moustachioed crook is a wild symbol who can steal extra wins as he stands in for others. He can land on a green or gold backdrop, with the golden version spawning extra wilds. All wild symbols leave ‘Sticky Frames’ in their places. If another wild lands in the same spot, a multiplier increases by 1x, to a maximum of 5x.

They remain on the reels of the Unusual Suspects online slot until the Detective arrives on the scene. He’s another wild who fills all accumulated frames, making a win much more likely.

Siren scatter symbols in two places on the top row trigger Nudging Respins, as their reels move down one row at a time as others respin. You need three, four, or five scatters in view to earn ten, 15, or 20 free spins of the reels respectively. Two scatters also build in a Booster Meter, and you need 50 to launch the free spins. There’s also an option to gamble for the free spins, but beware as they could be stolen away if the gamble goes wrong.

The Sticky Frames feature is active throughout this Unusual Suspects slot machine round and unlike the base games, they don’t vanish when the Detective appears. Collect detectives in a meter to release four Big Boss multiplier symbols this order –
