At the start, young Sonic fans choose to play 1P or 2P, Game Mode or Story Mode, and easy or hard difficulty. Once these decisions have been made, the wee ones must settle on a character to act as their avatar: Sonic, Tails, or Amy. In Game Mode, players can choose whichever games they want to play with no overarching goal. In Story Mode, each floor's games are played in succession for points. The goal is to amass more points than Eggman (or your opponent) by the end of each floor in order to proceed. Most 2P games are played in turns, but three (Car Race, Kinobori Race, and Tama Ire Race) are simultaneous, with each player in command of a different button.

   Each page of the game book represents a different floor of the Gameworld. Kiddies can choose to dive right into a game or chat with the local anthropomorphic patrons (Sonic, Tails, Amy, Flicky, Pocky, Kucky, Ricky, Picky, Rocky, or Pecky). There are 5 stages altogether (4 floors plus the roof), and each contains 3-5 attractions for a total of 17 different minigames.

1F Car Race (カーレース) -- Beat Eggman in a one-lap kart race around a circular track. Tap the green button repeatedly to accelerate. First place earns 20 points; second place earns 10. In case of a tie, both players get 20. Eggman's speed increases when playing on hard mode. Kinobori Race (きのぼりレース) -- Tree climbing race. Tap the green button repeatedly to make your Ai-ai monkey bot scuttle up and down the palmtree as many times as possible within 60 seconds. First place earns 20 points; second place earns 10. In case of a tie, both players get 20. When playing on hard mode, Eggman's Ai-ai climbs faster than on easy. Tama Ire Race (たまいれレース) -- Literally, "ball receptacle" race. A ski ball game with racing icons at the top of the screen. The more points you get with a shot, the more distance your icon will cover. Wait for the power meter to reach the ideal level, then roll the ball with the green button. First place earns 20 points; second place earns 10. In case of a tie, both players get 20. On hard mode, your opponents race faster and there's no score display to guide each roll. Shoot Game (シュートゲーム) -- Toss 5 basketballs into one of four dashing bipedal hoops. Move the cursor left and right with the blue and green buttons, respectively, and shoot with the red button. Each basket counts for 4 points, but sink all 5 and you get an extra 10 point bonus (for a total of 30 points). On hard mode, the baskets run faster and the scoring area for each is smaller.

2F Hataage Game (はたあげゲーム) -- Flag raising game. Eggman raises 1 or 2 flags corresponding to the blue and green buttons on the keypad. The object is to quickly tap the buttons corresponding to the flag(s) raised. The game ends after 50 seconds or 3 mismatches. A perfect game is worth 20 points, one miss equals 10 points, and 2 misses equal 5 points. On hard mode, the game lasts for 90 seconds, Eggman whips the flags up at a faster pace, and 3-flag combinations are possible. UFO Catcher (ユーフォーキャッチャー) -- Hold down the red action button until the crane hovers over the toy you have your eye on, then release the button and the claw will lower and attempt to grab whatever is directly below, be it toy or air. You have 5 chances, with each successful grab being worth 4 points. On hard mode, the claw's gripping radius is less forgiving. Eggman Tataki (エッグマンたたき) -- Eggman assault. Whack-a-mole featuring Eggman's glorious mug. Use the Touch Pen to maneuver the cursor over the Eggman heads, and use the red action button slam down the mallet. Bop as many noggins as you can within the time limit. 0-14 bops equals 0 points, 15-20 equals 10 points, and 21+ equals 20 points. On hard mode, the heads pop up faster and the point requirements are stricter: 0-39 for 0 points, 40-49 for 10 points, and 50+ for 20 points. Uranai (うらない) -- Fortune telling. Enter your birthdate along with the birthdate of your desired partner and the game whips up a compatability rating.

3F Slot Machine (スロットマシーン) -- Use the Touch Pen to bet Rings. Get three images in a row for points: cherries equal 3 points, Tails is worth 10, Sonic 20, BAR 50, and three 7's score a whopping 200. Roulette Game (ルーレットゲーム) -- Place your bets with the Touch Pen and hope the spinner lands on your marks. Shinkeisuijaku (しんけいすいじゃく) -- Nervous breakdown, the Japanese title for Concentration. Match up pairs of cards from a group of 12. The game ends if you screw up more than 10 times. You can earn 0, 2, 5, 10, 20, or 30 points based on how many mismatches you made. On hard mode, you're only allowed 5 mismatches. Poker Game (ポーカーゲーム) -- Use the Touch Pen to bet Rings. You're dealt a hand of 5 random cards and the object is to construct matching groups. Use the Touch Pen to select any cards you want to hold and trade the rest for new cards from the stack. Points are distributed as follows: No Pair = 0, One Pair = 1, 2 Pair = 2, 3 Card = 3, Full House = 4, 4 Card = 8, and 5 Card = 16. Bakudan Nuki (バクダンぬき) -- The title is a pun of Babanuki, or Old Maid, with the maid (baba) being replaced with a bomb (bakudan). Both players begin with 5 or 6 cards, and out of the 13 all are pairs except for a single bomb card. Keep pulling random cards out of Eggman's deck to pair up with cards in your own hand. Once all the pairs have been removed from the deck, the person left holding the bomb card is the loser.

4F Janken Game (ジャンケンゲーム) -- Rock-paper-scissors game. Challenge Eggman in the ultimate game of honor and prestige. Use the Touch Pen to choose your maneuver in preparation for Eggman's randomly-selected onslaught. The game ends after 5 rounds, with point distribution as follows: lose 3 or more rounds for 0 points, 2 rounds for 3 points, 1 round for 10 points, or win a perfect 5 rounds for 20 points. Tamago no Nakami wa? (たまごのなかみは？) -- What's inside the egg? 4 eggs, one of which contains Flicky, are laid out on a table. Keep your eye on the Flicky egg as Eggman mixes them up. Once the Doc has done his dirty work, try to pick out the egg containing the bluebird of Sega lore. The game lasts 4 rounds or 2 screw-ups, with each successful guess worth 5 points. On hard mode, Eggman whips the eggs around faster and if you make even one bad guess, the game ends. Kakutou Roulette (かくとうルーレット) -- Hand-to-hand fight roulette. Sonic and Eggman engage in bloody mortal combat. You control the action with a roulette that picks a random attack maneuver. Use the Touch Pen to start and stop the roulette at will. The ensuing action depends on where the cursor stops: fist (Sonic punches), foot (Sonic kicks), spin (Sonic spins), Eggman head (Eggman attacks), or question mark (random). Sonic starts with 10 hit points while Eggman begins with 5. The winner earns 20 points. On hard mode, both Sonic and Eggman begin with 5 hit points.

roof Chaos Sagashi Game (カオスさがしゲーム) -- Chaos search game. Once on the rooftop, retreat through all 4 levels of the Gameworld in a race against Eggman to find the Chaos Emeralds hidden on each floor. Move your character with the four directional buttons and investigate all the game machines. If you encounter a trap, you'll be momentarily stunned. Once all 5 Emeralds have been located, the character holding the most wins the game.
