Secret exits (Red flags) have been the ribbon that ties together all side-scrolling Mario games and hence they’ve been included throughout every game. In New Super Luigi U, there are 12 of them hidden amongst the world, every area has at least one while some may contain more.
Unlocking these Secret exits is very beneficial as they lead you to a hidden level and show you the way toward shortcuts that span between the worlds. You will need to collect every Star Coin from these hidden levels to find the mysterious Star Road.
The locations of the Secret Exits are the same across both New Super Mario Bros U and New Super Luigi U.
