The game is a typical "match the falling blocks" game but it makes use of different types, friend blocks, star blocks, bomb blocks, and hard blocks. Three friend blocks stacked or matched in a row between will disappear. Bomb blocks will destroy a full row. The elimination of Star Blocks removes stars from a Clear Count which must be emptied to clear every stage.
The game had a remake on Super Famicom with the same name as the Game Boy game but because the North American SNES ended its life, the game never left Japan until it was made available, untranslated, on the Nintendo Switch Online service in 2023 (the original Game Boy game wouldn't be added until two years later). The 16-bit remake takes most of its design aesthetic from Kirby's Dream Land 3, but the story mode features a few characters that were otherwise exclusive to Kirby Super Star (such as Knuckle Joe, Chef Kawasaki and Meta Knight).
Tropes seen across both games:
- American Kirby Is Hardcore: Averted with the North American cover of the Game Boy version which has Kirby smiling.
- Border-Occupying Decorations: The game features two Super Game Boy borders, both depicting Kirby and the Animal Friends. The first border features them against the various blocks that appear in game, while the second depicts them, a bunch of stars, and a rainbow against a blue checkerboard.
- Excuse Plot: The Super Famicom version's Story Mode. King Dedede blasts Mr. Star out of the sky with a cannon which shatters him into various pieces and blows them across Dream Land. Kirby sees what happened and offers to get him back together.
- Harder Than Hard: On "Insane!" difficulty, the clear objectives rarely ever drop below 100, there are no intermissions between stages, and you have to clear 50 puzzles (as opposed to 16 on the previous difficulty levels) in order to win the game. Scoring exceptionally well on the Score Attack and Time Attack modes also unlocks their own "Insane!" difficulty, where drop speed and line clear speed are always maxed out.
- Songs in the Key of Panic: The music becomes more frantic and fast-paced the more the field fills up with blocks.
- Super Title 64 Advance: The planned North American name of the Super Famicom title was Kirby's Super Star Stacker.
- This Means War!: King Dedede says this at the beginning of the Normal mode.King Dedede: Hey, Kirby! This means war! If you can stack this many *'s, you win!
- Video Game Remake: The Japanese-only Super Famicom version.
