Kirby’s Blowout Blast is based on Kirby 3D Rumble, which is a mini-game in Kirby: Planet Robobot. The game follows the same mechanics as the original Kirby game, Kirby's Dream Land, meaning there is no copy ability, like in future iterations of the series. The main difference in Kirby’s Blowout Blast is the introduction of the 3D environment, which changes the gameplay around. For instance, Kirby can now spit enemies he has swallowed in several different directions, with the introduction of a small arrow to indicate the direction Kirby will spit the enemy out.
Even though the game is fully playable in 2D, the use of the 3D gimmick gives the world a much greater sense of depth, and can sometimes help with the gameplay, just like it happened in Planet Robobot.
Each completed stage awards the player with bonus points, depending on how fast the stage was finished, how many enemies were killed, if all coins were collected and if damage was avoided. A gold ranking (or higher) will unlock the EX versions of the corresponding world, and since there are initially five worlds to beat, obtaining that rank in each single world will double the game’s length, making 10 worlds available.
Kirby themed Amiibo work with the game, unlocking several cosmetic extras. Other extras are also unlocked by having Kirby Planet Robobot.
