CLASSIC ARCADE BENCHMARK 01: Pinball Overdrive. Build a complete playable browser arcade game as one self-contained index.html using Three.js. Create an original pinball score attack with two flippers, a visible drain, ball serve, at least three distinct scoring elements, score, local high score, and instant restart. The core loop must reward aimed shots, repeatable sequences, and a high-value route rather than random flailing. Add a visible Overdrive meter that fills through skilful target play. The player must choose when to activate Overdrive; it should temporarily increase scoring potential while adding real danger or sacrificing a safety advantage. Use keyboard and touch-friendly controls. Keep the visual theme, story, materials, target names, and audio entirely open, but make ball, flippers, drain, objectives, and danger readable. No real table clone or external asset pack. Submit the final index.html only, not a mockup or explanation. It must run in a modern browser with no build step.
