HOW TO PLAY

This toy runs on spring power—no electronic bounce.

1. Tap the TIMER for one turn, press and hold for automatic winding, or drag it in full clockwise circles. Each turn adds 10%; ten turns reach MAX.
2. Every new game and reset starts with an empty spring and POWER OFF. Switch POWER ON, choose 1 or 2 players (the default is 1), wind the TIMER ten turns to MAX, then pull the P1 red SERVE lever once; Player 1 always serves first.
3. Watch which 1–3 track the red dot takes. Press the matching button any time before it arrives. Once your press is registered, you can let go—the return is locked in.
4. Player 1 always makes the opening serve. In 1-player mode, the top acts as a practice wall and you defend the bottom. In 2-player mode, one player takes each end; after every point, the player who missed serves next.
5. A miss gives the opponent a point. The ball stays at the missed end, so the player who lost the point serves next using their own lever. First to 10 wins. A full 10-turn wind lasts the entire game, so wind only before a new game or after one ends.
