• Wall Wrapping: Touch screen edge → appear on opposite side (no death)
• Self Collision: Hit your own body → death
• Player Collision: Hit opponent's body → death
• Head-to-Head: Two heads collide → both die
• Obstacles: Hit gray blocks → death

Scoring System

• Food: 10 points per red square (round score)
• Power-ups: 5 bonus points per item (round score)
• Survival Bonus: Being the last snake alive usually determines winner

Score Tracking

• Round Win: +1 win for victor (cumulative display)
• Tie: No one gets win point

Power-up Effects

• Speed Boost: Double speed for 3 seconds (glowing effect)
• Grow: Instantly add 2 body segments
• Shrink Enemy: Remove up to 2 segments from opponent (won't kill)

Strategy

1. Control the Center: Middle positions have more escape routes
2. Use Power-ups Wisely: Speed boost helps escape dangerous situations
3. Block Opponent: Use your body to limit opponent's movement
4. Avoid Head-on Collisions: Don't charge directly at each other
5. Exploit Wall Wrapping: Use wrap-around feature for surprise attacks
