- Debate on principle, not number
- Game players came up with a convincing argument
- Have the same card tie in war
- Get rid of 2 out of 3, and instead count to see who has the highest carbon score loses
- Clarify that this is a take on war
- Room for improvement and expansion

Updated Revisions for Carbon Clash
Carbon Clash Revised Rules: PA Edition
Objective: Have the lowest total carbon footprint (fewest cards) when the main deck runs out.
1. The “Clash” (The Win/Loss Flip)
- On your turn, choose one card from the top of your pile to play into the center.
- All players reveal their chosen card.
- The player with the HIGHEST carbon footprint (highest score) must collect all cards played in that round.
- These cards go into your Secondary Pile (your “Carbon Debt”).
2. The Debate (Tie Rule)
If two players play cards with similar emissions (e.g., a Hybrid Car vs. Carpooling):
- Players enter a Debate.
- Each player has 15 seconds to argue why their activity is worse for the environment, specifically (e.g., “PA has a high-density bus network in Philly, making it more efficient than a single Hybrid, therefore, a hybrid has worse emissions”).
- The other players vote. The winner of the debate takes the cards.
3. Pennsylvania “Learning Twist.”
If you play a “High Impact” card (score 200+), you may discard it instead of giving it to the winner if you can name one specific PA-based initiative or fact (ex, “The state’s transition toward natural gas over coal”).
End of Game & Scoring
The game ends immediately when any player’s Primary Stack (the cards they were dealt at the start) runs out.
Determining the Winner:
- Count the cards in your Secondary Pile.
- The player with the FEWEST cards wins.
- Tie-breaker: If card counts are equal, sum the carbon scores. The lowest total score wins.

Game 3 Carbon Clash
Players
2 players
Time
10–15 minutes
Objective
Win the most cards by playing lower carbon emission activities than your opponents.
Deck
- A single deck of Activity Cards
- Each card includes:
- Activity (e.g., Driving, Flying, Biking, Solar Power)
- A carbon score (number value)
Setup
- Shuffle the deck
- Deal all cards evenly to players (face-down)
- Players do not look at their cards
- Keep cards in a stack in front of you
Gameplay
1. Flip
All players flip their top card at the same time
2. Compare
- The card with the LOWEST carbon score wins
- (Reverse of traditional War)
3. Collect
- Winner takes all played cards
- Place them at the bottom of your stack
Carbon Clash (Tie Rule)
If two or more players tie:
- Each tied player places 1 card face-down
- Then flips 1 card face-up
- Compare again → lowest carbon wins all cards
Learning Twist
Before taking the cards, each tied player must say one way to reduce emissions related to their activity
- If they give a valid answer → continue
- If they can’t → they lose 1 extra card to the winner
End of Game
Choose one:
- Play until one player has all the cards
OR - Set a timer → player with the most cards wins
Key Rules to Remember
- Lower carbon = better
- Always flip at the same time
- Only use the card deck—no board, tokens, or extras
