The levels where they are unlocked are the following: World 1- to World Mushroom, World 3- or World Mushroom - B to World Flower, and World Flower - A to World 6.


Unlike most other stages, Assist Blocks will never appear. There is a Red Coin challenge in each cannon stage, which yields a Gold Flower in the spare item slot upon completion. Afterwards, the player ends up in another world. They usually contain common enemies in the cannon's 'home' world at the end of each one, a sign appears pointing right, at which Mario/Luigi jumps out of the level. Mario/ Luigi constantly dash in these levels, even if the buttons are not pressed, in a similar fashion to Super Mario Run levels. When the countdown reaches 1, Mario or Luigi is shot out into a nighttime level with a Super Mario Bros.

2, Warp Cannons are blue, and when they are entered, a countdown appears.
