🎳 Bowling Stars: Angular Velocity and Lane Geometry

Bowling Stars brings the physics of the bowling alley to the browser with a focus on angular velocity (spin) and vector aim. Unlike simple point-and-click bowling games, this title simulates the "Hook Shot" used by professionals. The ball is not just a rolling sphere; it interacts with the lane's friction (simulated oil patterns) and the player's applied side-spin to create curved trajectories.

This game is a study in consistency and precision. A strike requires hitting a specific "pocket" (between pin 1 and 3 for right-handers) at a specific angle (usually 6 degrees). Bowling Stars gamifies this geometric requirement through timing-based power bars and directional arrows.

🧠 Cognitive & Physics Skills

The gameplay reinforces trajectory planning:

• Vector Addition: The final path of the ball is the sum of its forward velocity vector and its rotational spin vector. Players learn to visualize how these two forces combine to create a curve.
• Error Correction: If a shot goes too far left, the player must adjust their starting position or reduce the spin. This iterative calibration is a core scientific skill.
• Timing Precision: The power meter oscillates rapidly. Stopping it at the exact maximum requires fine motor timing (hand-eye coordination).

🎮 Mechanics & Pin Physics

The engine handles the chaotic collision of pins:

• Rigid Body Collisions: The pins interact with each other. A good strike relies on "pin carry"—where the pins hit by the ball fly sideways to knock down other pins. A straight ball often causes a "split" (leaving separated pins), while a curved ball drives pins into the center.
• Power vs. Control: High power creates more pin scatter ("messenger pins") but makes the aim meter move faster, increasing the risk of a gutter ball. Managing this risk/reward is key.
• Ball Stats: Unlockable balls have different stats for Weight and Hook. Heavier balls knock down more pins but are harder to spin.

🏆 The Perfect Game Strategy

1. Master the Hook

Straight shots rarely result in strikes because the ball deflects off the head pin. You must apply spin. Aim slightly to the side and apply spin towards the center. This increases the entry angle into the pocket, maximizing pin collision.

2. Spare Conversion System

Memorize the "3-6-9" rule. For every board (position) you move your feet, the ball moves a specific amount at the pins. If you leave a pin on the left, move your starting position to the right to change the angle diagonally.

🛡️ Technical Info

Polished sports arcade:

• Visuals: 3D rendering of the lane allows for accurate depth perception.
• Input: Mouse swiping or click-timing allows for intuitive control over speed and direction.
