Rulebook v1.7

SATOSPOLIO

Based on the official Monopoly rules

1Game Philosophy

This game replicates, in a playful setting, the coexistence of two opposing systems of value:

ETFs bank notes

Instruments denominated in satoshis, but with no real intrinsic value. They are a promise of the traditional financial system โ€” they reference Bitcoin without being it. Just as in real financial life, an ETF is not a monetary unit: it is a piece of paper claiming to be worth something, issued by an entity that can create more from nothing.

Satoshis real vouchers

Scarce, with real value backed by Bitcoin Lightning. They truly exist. They are not a promise โ€” they are the asset.

Having ETFs looks like having sats. But it is not the same thing.

The ultimate goal is not just to accumulate properties โ€” it is to accumulate the greatest real value in satoshis by the end of the game.

1.1Starting the Game

Each player rolls the dice to determine who goes first. The highest roll starts.

All players begin the game on the Genesis square.

If a player rolls a double (the same number on both dice), they may play again immediately. After completing their options, the player rolls again. If they roll another double, they play again. After completing their options, the player rolls a third time. If they roll a double again, they are sent to Jail. The player must move their piece to the "In Jail" space, receiving and paying nothing on that turn.

The 8 players are identified by the classic cryptography names, traditionally used to represent different roles and participants in a secure communication protocol:

Alice ยท Bob ยท Carrie ยท David ยท Eve ยท Frank ยท Grace ยท Heidi

Each voucher contains a QR code protected by a fold. The QR code is only revealed and redeemed at the end of the game.

How Redemption Works

The custodian is the one who provides the game experience, having set up all the components. They will hold a wallet with the vouchers already created.

At the end of the game, each player redeems the sats they effectively secured during the game โ€” whether by keeping their initial vouchers, winning vouchers from other players, or losing them to others.

Redemption is done via the QR code on each voucher, which instructs the custodian's wallet to send the corresponding amount via Bitcoin Lightning to the wallet of the player holding it.

Only vouchers physically in a player's possession at the end of the game โ€” including those locked in their Personal Safe โ€” are eligible for redemption, regardless of who originally received them.

2.2 ETF Notes bank money โ€” no real value

Instruments denominated in ETFs, issued by the game bank. Their denomination references satoshis but does not represent them. There is no initial distribution of ETFs to players. ETFs enter circulation exclusively through game mechanics โ€” by passing Go, through Volatility and Consensus cards, and other events involving the bank. If the bank runs out of notes, new money is created on any piece of paper. These ETFs have no value outside the game.

2.3 Player Wallets

Each player must maintain two separate and visible wallets throughout the game:

Note on the "s" suffix on cards: The "s" suffix on property cards represents satoshis as a universal unit of account. The nature of payment โ€” real voucher or ETF โ€” is always determined by the rules in force for each type of transaction, never by the card itself.

2.5 Other Components

Identical to traditional Monopoly: board, dice, player pieces (Bitcoin coins encased in colour-coded rings identified by name), property deeds, ASICs (houses), Farms (hotels), Volatility and Consensus cards.

2.6 Personal Safe

Each player receives at the start of the game an envelope identified with their name and piece colour, containing their personalised record sheet. The envelope is handed to the bank, which holds it throughout the game in a safe visible to all.

The bank acts as a neutral guardian โ€” it has no access to the contents, only custodying the envelope. Only the owner opens and closes their safe, always in view of the other players.

There are 8 record sheets, each personalised with the player's name at the top:

PLAYER'S SAFE โ€” ALICE
#NoProperty / ASICs / FarmsLocked Sats
TOTAL

The number (#No) corresponds to the identification number printed on each property card. Locked vouchers are physically placed inside the envelope alongside the record sheet, identified by the asset number they belong to.

3Official Exchange Rate

Before starting the game, players collectively define the official exchange rate between sats and ETFs. This rate is fixed for the entire game.

Suggested example: 100 sats = 1,000 ETFs

The rate is used exclusively for:

The bank does NOT exchange. Ever.

4Monetary Circulation Rules

Fundamental Principle

Satoshis circulate only between players or to the Mining Pool (see section 5). The bank operates only in ETFs.

4.1 What is paid to the Bank in ETFs โ€” with exception

Exception โ€” Mining Pool Rule (see section 5)

When a player has no ETFs to pay the bank and only has sats, that payment is made in sats and goes to the Mining Pool, not the bank. This rule applies to any payment owed to the bank: fines, taxes, jail fees, or property purchases.

4.2 What is paid between Players

The preferred and priority payment between players is made in satoshis. ETFs are accepted as an alternative when the debtor has insufficient sats.

Situations covered:

4.3 Exchange between Players

If a player needs ETFs but only has sats (or vice versa), they can exchange with any other player at the official rate. The bank does not intervene in this process.

5Mining Pool Community Rule

The Mining Pool functions as a community sat reserve, placed on the board, visible and accessible to all players.

5.1 Depositing into the Pool

When a player cannot pay the bank in ETFs because they only have sats, that payment is made in sats and placed in the Mining Pool. The bank does not receive or record this value.

5.2 Collecting from the Pool โ€” "Mining Pool" Square

The right to collect sats from the Pool is activated exclusively when a player lands on the Mining Pool square on the board.

At that moment, the player may collect sats from the Pool up to the amount they already hold in sats in their wallet at the time of landing โ€” never more than that.

Example

  • Mining Pool has 800 sats accumulated
  • The player lands with 300 sats in their wallet
  • The player collects 300 sats (parity limit)
  • The remaining 500 sats stay in the Pool

This limit ensures that community sats do not unbalance the game by abruptly enriching a single player.

5.3 Accumulation and End of Game

Sats in the Pool accumulate throughout the game until collected. They can be partially collected at different times by different players, always respecting the parity limit.

If at the end of the game there are still sats in the Mining Pool that no player managed to collect, those sats revert to the custodian.

6Buying Properties

6.1 Buying from the Bank

6.2 Bank Auction

6.3 Buying/Selling between Players

7Value Locked in Assets Deeds, ASICs and Farms

7.1 Unified Principle

Whenever an asset (property deed, ASIC or Farm) is transacted or built with payment (total or partial) in sats, those sats are locked in that asset. The asset gains recorded real intrinsic value.

Locked sats are recorded on the Personal Safe record sheet (section 2.6) with the asset's identification number. The corresponding vouchers are physically placed inside the envelope, identified by the asset number.

7.2 Accumulation in Deeds

With each new sat transaction, the locked value in the deed accumulates:

New locked value = Previous locked value + Premium paid in sats

Example

  • Initial purchase: 500 sats locked
  • 1st sale (+ 300 premium): 800 sats locked
  • 2nd sale (+ 400 premium): 1,200 sats locked

7.3 Accumulation in Buildings (ASICs and Farms)

When a player builds ASICs or Farms with financing (total or partial) in sats โ€” notably in private agreements between players โ€” the invested sats are locked in the building and recorded separately from the deed on the record sheet.

The investor may agree on a future share of rent in exchange for this financing, with terms freely negotiated.

7.4 Sale with Premium

The buyer pays:

If the buyer has insufficient sats for the premium:

7.5 Sale of Property with Buildings

When a property with ASICs or Farms is sold between players:

7.6 Demolition or Bank Repurchase

When the bank repurchases buildings (mortgage or bankruptcy):

7.7 Assets without Locked Sats

Assets purchased entirely in ETFs have no locked sats. Their value at the end of the game is calculated at the official exchange rate, although this holds no interest for a real economy, only to determine the winner. As such, performing this calculation is optional.

8Rent

8.1 Assets with Locked Sats

The owner may demand payment in sats (total or partial). The debtor may propose equivalent ETFs โ€” the creditor decides whether to accept.

8.2 Assets without Locked Sats

Even if the asset was purchased entirely in ETFs, rent may be paid in real sats if both parties agree. The creditor always has the right to accept or refuse sats in lieu of ETFs.

8.3 Rent Insolvency

If the debtor cannot pay (neither in sats nor ETFs):

  1. Attempt exchange with another player
  2. Sell properties to other players
  3. Mortgage properties to the bank (receive ETFs)
  4. If still insufficient โ†’ Bankruptcy

8.4 Collecting Rent

The property owner must collect from the player who landed on their property immediately and before the next player rolls the dice. If this does not happen and the next player rolls, the owner loses the right to collect rent for that turn.

9Go and Special Squares

9.1 Passing Go (Genesis)

9.2 Jail

A player goes to Jail when:

If the player goes to Jail, they must immediately move their piece to the "In Jail" space, ending their turn, and the next player rolls. While going to Jail, the player receives no money, properties, rewards, bonuses, fines, taxes, Volatility or Consensus cards, nor any other value accumulated from other rounds.

If the player is not "sent" to Jail but lands on the "In Jail" space, they are merely visiting. The turn ends and the next player rolls.

To try to leave Jail, the player has the following options, in the order listed:

  1. Pay the Bank 500 ETFs and leave, playing normally with the dice result;
  2. Use the "Get Out of Jail Free" card and leave, playing normally;
  3. Buy the "Get Out of Jail Free" card from another player and use it to leave;
  4. Roll the dice. Rolling doubles means leaving and playing normally with the dice result.

A player serving time in Jail receives no values during that period โ€” rents, Pool collections or any other payments owed are suspended until they leave.

9.3 Mining Pool (board square)

9.4 Volatility and Consensus Cards

10Bankruptcy

A player declares bankruptcy when they cannot settle a debt after exhausting all options (exchange, sale, mortgage).

11End of Game and Winner

The game ends when:

11.1 Final Count

1
Sats in wallet

Count the sat vouchers each player still holds.

2
Sats locked in assets

Open each player's personal safe and add up all locked sats recorded on the record sheet (deeds + ASICs + Farms).

3
ETFs in wallet and in assets without sats (optional)

Record each player's total ETFs. This step is optional โ€” ETFs represent no real value and serve only as a tiebreaker if two players have exactly the same total sats.

4
Total per player

Sats in wallet + Sats locked in assets = Total in Sats

The player with the highest sat total is the winner. In case of a tie, the ETF total from Step 3 serves as the tiebreaker.

11.2 Voucher Redemption

All players reveal the QR codes on their vouchers by unfolding them and proceed to redeem via Bitcoin Lightning the amounts they effectively hold โ€” including vouchers that were locked in their Personal Safe. Each player redeems only the vouchers in their possession, regardless of whether they received them at the start of the game or won them during play.

Any sats remaining in the Mining Pool that were not collected during the game revert to the custodian.
