List of Possible Combinations
In all of the following layouts, 1-8 Sunflowers is/are also included (8 plants are Puff-shrooms, being the number of sunflowers), dependent on the amount of sun you have, as well as your streak. However, the Scaredy Layout has more sunflowers than usual (up to 13) and is also the rarest. The frequency of Scaredy Layout notably affects how far a player can go.

Other plants in each layout: The Magnet and Fume Layouts are the most difficult one, due to the fact that Magnet-shrooms stop the use of Digger Zombie, Ladder Zombie, Buckethead Zombie, and Football Zombie until the end and the Fume-shrooms kill Dancing Zombie (and its Backup Dancers) and Imp quickly. Hence, only Conehead Zombie, Pole Vaulting Zombie, Bungee Zombie (which are all weak) can be used initially. Players will need to use a lot of Sun for this set-up.
