The player plays as Qbby, a box with legs who can create boxes out of his body. The player must solve puzzles using these boxes, which can stay on Qbby or be detached. If they remain attached to his body, Qbby can use the boxes for movement by moving to the farthest box, destroying the boxes in the process. Crowns are placed in every level, and can be collected for an added reward. Bye-Bye BoxBoy! introduces different kinds of boxes, which appear in certain levels and have different effects depending on the type. The game also introduces Qbaby, a small box that must be escorted to the goal in certain levels. After beating the game, Challenge Worlds unlock, featuring more difficult levels. The player can scan an amiibo of Kirby or another Kirby character to have Qbby wear a costume that makes him look like that character. Scanning the Qbby amiibo turns the entire game a shade of green that makes it look like it is being played on a Game Boy.

Bye-Bye BoxBoy! was developed by HAL Laboratory, the developers of the previous games as well as the Kirby series. The game was released for the Nintendo 3DS on April 12, 2017 in North America. In Europe, the game was released on March 23. A demo was released to promote the game, featuring levels from all three games in the series. The game also released with a Qbby amiibo, which could only be obtained in Japan.
