What Makes It Addictive

The core loop exploits the same psychology as slot machines:

• Variable reward - crash point is random
• Near-misses - could have held 2 more seconds!
• Loss aversion - bets make crashes feel real
• Streaks - daily bonus keeps you coming back

Tech Stack

• Pure HTML/CSS/JS (1735 lines, single file)
• Web Audio API for synthesized sounds
• Canvas 2D for chart rendering
• localStorage for persistence
• Zero dependencies
