How to Play Lock'n'Chase
Quick start
- Move through the maze collecting gold.
- Cross a marked doorway with a police officer following.
- Use Lock to close that doorway behind you.

Lock'n'Chase — About this game
Lock’n’Chase makes a temporary gate the thief’s main answer to the pursuing police. The gate closes at the last marked doorway crossed, blocking the thief as well as the officers, so its placement must leave another escape route. Only two can remain closed at once, and automatic gates elsewhere can change the maze without warning. Collecting the gold opens the way out, but leaving a useful route to that exit is part of the clear.
