|“||Try to roll all of the Kirbys into the holes. This one is tricky, so you'll have to tilt very carefully!”|
|— Instruction manual description • Kirby Tilt 'n' Tumble|
In the first round of this game, the player starts with two Kirbys. His/her goal is to get all the Kirbys to fall into the holes before the time runs out. This can be achieved by tilting the Game Boy to steer them into the holes, just like the gameplay of the main game. As the Kirby's Roll-o-Rama progresses, Gordos will attack and more Kirbys will be added. If the Kirbys hit two Gordos or the time runs out, the game will end.
Like all the sub-games in Kirby Tilt 'n' Tumble, Kirby's Roll-o-Rama can only be played if Kirby obtains the Bonus Star and clears the level he found it in.
- The name "Roll-o-Rama" was later given to the Kirby-less version of the canceled Kirby Tilt 'n' Tumble 2.
- The title screen for this sub-game shows four pink Kirbys and one blue one. Coincidentally, the Kirbys in Kirby Mass Attack also appear in these two colors.
