How to play Mystery Doctor

Walk into the clinic where every patient leaves behind a piece of the puzzle, a brain, a syringe, a vial of something that glows under the lights. Your job is to line up the organs and instruments the doctor collects: match three or more across the exam table and the stacked body charts fill in the missing pieces. When three or more ambulances pull up to the door, the clinic clears for ten to thirty house calls, and every piece you collect during that run costs nothing. Mystery Doctor is a medium volatility, fixed payline slot from KA Gaming. It uses a 5-reel grid where matching symbols pay across adjacent reels from the left. Stacked Wild symbols can cover multiple positions and help complete winning lines. Landing 3, 4, or 5 ambulance scatters triggers 10, 20, or 30 free spins. Here is how you play.

Pick a stake and spin the 5-reel grid.
Watch for three or more matching symbols to land on one of the 25 fixed paylines.
Look for stacked Wilds that can substitute for regular symbols to form or extend wins.
Land 3, 4, or 5 ambulance scatters anywhere on the reels to trigger the Free Spins round.
Play through 10, 20, or 30 free spins, depending on the number of triggering scatters.
