A web-based horror game inspired by Vietnamese coin toss mechanics with a dark twist.

Players choose between "NGÚP" or "ỬA" and the system randomly generates 4 results from ["NGÚP", "ỬA", "ÚP", "NGỬA"]. If the player's choice matches the outcome, they receive a special victory animation. If they lose, they experience a horror jumpscare.

• Polished UI/UX: Dark horror-themed interface with glitch effects
• Dynamic Animations: Multiple victory and jumpscare variations
• Progressive Horror: Random creepy messages and visual glitches
• Score Tracking: Keep track of wins, losses, and total score
• Responsive Design: Works on both desktop and mobile devices
• Audio Effects: Background music, coin flip sounds, and jumpscare audio (placeholders included)

1. Open index.html in a modern web browser
2. Click "BẮT ĐẦU" (Start) to begin
3. Choose either "NGÚP" or "ỬA"
4. Watch the coins flip and see your fate!
5. Try to survive as many rounds as possible

• Screen shake effect
• Loud sound effect (when audio is added)
• Static noise overlay

• Random glitch effects during gameplay
• Creepy messages appearing at intervals

Modify the probability values in script.js:
