World 1 (Puzzle & Dragons: Super Mario Bros. Edition)

World 1 is the first world in Puzzle & Dragons: Super Mario Bros. Edition. This world features typical grassy plains with many colorful hills, similar to New Super Mario Bros. 2, with Orbs scattered about the map. It consists of nine levels and a Toad House. The player starts the game with Small Mario and Small Luigi as Leaders, and Red Toad as a Helper. Larry Koopa is the boss of this world and is fought in his castle and airship. The music is an arrangement of World 1 from New Super Mario Bros. Wii.

Clearing World 1-1 unlocks Green Toad; World 1-2 unlocks Blue Toad; World 1-4 unlocks Yellow Toad; unlocks Super Mario and Luigi as Leaders and the Transformation section at Toad Houses; World 1-6 unlocks Purple Toad and  unlocks Ice Mario and Ice Luigi as Leaders.

A more difficult version of World 1 exists as a Special World: ★World 1.

World 1-4
After fighting the second set of enemies, the player finds a branching path. To reach the secret exit, the player must clear more Light Orbs than Fire Orbs. However, the course does not contain any Light Orbs, so the player needs to bring an ally that can create them. Upon defeating the boss at the end of the secret path, the player unlocks World 1-5.
