Like Kirby's Pinball Land and most pinball machines, the player controls two flippers which hits the ball (which happens to be Kirby) to prevent it from falling into the bottom hole, or sink. In this sub-game, the player needs to tap on the on-screen button which controls the corresponding flipper. The player could also use L and R button to control the flippers. Kine initially plugs the hole and protects Kirby from falling into it, but once he saves him once, Kine moves away and the hole becomes a danger. However, Kine can appear again if the player manages to hit all the moles on the left and right side of the board.
In Level 1, the player needs to get Kirby into King Dedede's mouth to start a boss fight against Whispy Woods. In the next three levels though, enough stars must be collected until Dedede opens his mouth before Kirby can start the next boss fights - Lololo and Lalala in Level 2, Heavy Lobster in Level 3, and Marx in Level 4. The only way to hurt the bosses is by sending Kirby hurtling into them. Once Marx is defeated, the game is won.
The bosses retain their traditional attacks, but several of them are modified to fit a pinball game.
Heavy Lobster no longer jumps around like it does in the Halberd. Its flamethrower attack is changed into shooting cannonballs which explode into flames. It is the only boss who can actively dodge Kirby (the player's attacks).
Marx's gigantic laser and arrow attacks now point downwards, and he performs his cutter attack twice (4 waves). After he uses his black hole attack, he spits out the Kirbys pulled into the black hole. All of his other attacks are not available to him.
If the player collects enough stars after Dedede's mouth opens, a Warp Star will appear at the top of the board. The Warp Star can then be used to warp into a secret level. In this board, the player could play a game of roulette that's shown on the top screen for a limited time. Two Waddle Doos also appear in this board where they'll shoot Beam Whips to give Kirby a boost.
Once Kirby defeats Marx, the game shows a tip: Press and hold Right, Select, and B on the title screen. If done correctly, the player may hear and see a cat go across the bottom of the screen. Now touch the screen. Kirby will play against every boss.
