There are 2 ways to win a Heist:
  1. Catch the Thief directly on the map. (Easy and Medium only)
  2. Battle the Thief at the Hideout.
To catch the Thief you need to spot her moving around the map. Position your heroes near her on the map using the black circle. This shows her last known location. The size will show how precisely you know the Thief’s location, and the darkness will show how recently you saw the Thief. The black circle fades over time, and can disappear.

The Hideout is hidden in one of the POIs. Collect clues to shrink the white circle and narrow the location of the Hideout. Once you find the Hideout, you battle the Thief. Win or lose, the Heist ends after the Hideout battle.
