Trainer Tower Guide
Each of the four modes (Single, Double, Knockout, Mixed) gives a different prize for clearing all 8 floors. The prizes are Metal Coat, King's Rock, Dragon Scale, and Up-Grade. These are trade evolution items that are otherwise hard to get in FRLG, mostly limited to rare hidden pickups or low-chance wild holds.
Pick one of four modes and battle your way up 8 floors of trainers against a clock. Your completion time gets recorded. Single and Double use standard battle rules. Knockout is a gauntlet where your team's HP carries between fights. Mixed alternates formats per floor.
Islands One through Three unlock after you beat Blaine on Cinnabar Island. Bill takes you there as part of the story. Islands Four through Seven require beating the Elite Four first, then completing Celio's Ruby and Sapphire quest on One Island to get the Rainbow Pass.
You can physically reach all seven islands without it, but evolved Johto Pokemon only show up in the wild after you get the National Dex. That means 60 or more Pokedex entries plus completing Celio's quest. If you're only seeing Kanto species, that's why.
