Shuffle

"Placed characters will randomly swap places between each round."

- BATTD description

"TIP: SHUFFLE In this game, starting on round 5, Magic Man will randomly swap the positions of all your characters between each round.

Try and use versatile characters who will be effective bloon poppers no matter where they end up."

- Cuber's description to Shuffle rule in the Martian Games Shuffle is a rule in Martian Games. Every round starting from after Round 6, characters, allies, and sub-towers will swap to locations where the other towers were, regardless of said towers' placability, provided some towers (e.g. Max and Captain Cassie) are able to be placed on their respective terrains in the first place.

Strategy
Concentrate all your towers near one area so that they always can be in their optimal attack spots.
