How the game works

1. The game in three steps

1. Mint passports of any country. The first 10 cost 0.0005 ETH each, then the price doubles level by level.
2. Hold more than anyone else. You’re the country’s candidate.
3. Once the country has 50 passports, stay candidate for 7 days. You’re president and take the country’s treasury.

Every mint also pays 40% as rent to everyone holding an earlier passport of that country.

2. Passports

All 200 countries are open from the start. Mint as many passports as you want. Send and sell them freely.

Price. The first 10 passports of a country cost 0.0005 ETH each. Each next level is twice as big and twice as expensive. Every country has its own levels.

Where the money goes.

Rent. The rent from each new passport is split equally among all earlier passports of that country. The first passport has nobody before it, so its rent goes to the treasury. Rent goes to whoever holds the passport at the moment of each mint. Claim it any time. If you sell a passport, what it earned before the sale stays yours.

Example: you mint Japan No. 3 for 0.0005 ETH. By Japan’s 50th passport you’ve earned 0.0011 ETH in rent, about 2× your price. By the 150th, 5×. From level 2 on, a passport pays for itself once its country has about 3× as many passports as when you minted it.

Citizen number. Passports are numbered in the order they were minted in their country: No. 1, No. 2, No. 3. The number never changes.

3. Elections

Candidate. The wallet holding the most passports of a country. Every passport in the wallet counts: minted, bought, received, or moved from another wallet of yours.

Overtaking. The candidate changes as soon as another wallet holds strictly more. A tie keeps the current candidate. If the candidate gives passports away and several wallets end up tied for the most, there is no candidate until one of them pulls ahead.

Countdown. Once a country has 50 passports and a candidate, a 7-day countdown runs. A new candidate starts it over. The candidate minting more doesn’t. With no candidate, the countdown stops, and the next candidate gets a fresh 7 days.

Example: Anna has 12 Peru passports, Ben has 9. Ben mints 3: 12 to 12, Anna stays. Ben mints one more: 13 to 12, Ben is the candidate and the 7 days start over.

4. Closing

If the candidate doesn’t change for 7 days, they become president forever. The country closes at that second: its passports can’t be minted or moved, and rent stops. Rent earned before that stays with the holders.

After that, each in its own transaction:

• anyone inaugurates the president: the President passport goes to the president’s wallet;
• anyone burns the country’s passports, in batches;
• the president takes the country’s treasury whenever they want.

5. World treasury

Population. Each President passport carries its country’s population: how many passports the country had when it closed. A wallet’s population is the total of the President passports it holds. Sell a President passport and its population goes with it. The country treasury stays with the president.

End of the game. The game ends the second the last country closes. From then on, President passports can’t be moved until someone declares the winner; anyone can. The biggest population becomes world president and takes the world treasury and the World President passport. On a tie, more President passports wins. If that’s a tie too, the treasury is split equally and each winner gets a Co-President passport.

Unclaimed money. A country treasury the president doesn’t take within 12 months goes to the world treasury, or, once the game is over, to the world president. If money waits in the world treasury 12 months and the world president doesn’t take it, the world treasury passes to the next wallet by population. Anyone can trigger these transfers.
