Got this easily while grinding out the 1st level for the Fully Loaded achievement:
It is the 1st level called "The Bench" You will be fighting 2 lvl 1 thugs.
Usually the map starts out with a lot of red on the map other then that the cascade is pretty much luck based.
This place is a good place to grind since the team up tiles have not been introduced yet so more chance of getting cascade matches.
