The stock market board game · Season one · Robinhood Chain
Own a piece
of the board.
$MONO takes the board game you know and gives it a real market underneath. Every company tile is backed by a Robinhood Stock Token — Apple, NVIDIA, SPY, Tesla — and instead of buying a whole street you buy shares. Land on a company and buy in; when someone else lands there, the rent comes to the people who hold it. Nobody waits for a turn: everyone plays on their own clock.
The idea
A board game is a market with a dice roll attached. The classic version asks you to buy property and rent it out; $MONO asks the same question with real, tradable assets — and then puts the whole thing on-chain, so there is no bank in the middle.
The result is a board that behaves like a market: the price of a tile moves when people buy and sell it, popular tiles get expensive, quiet ones stay cheap, and the rent you earn grows as the tile you hold gets busier. Your position is not a score — it is a balance of shares you own and can sell whenever you want.
Play for fun, play to climb the leaderboard, or hand the whole thing to an AI agent and watch it trade. The rules are the same for everyone, and every trade is signed by the wallet that owns it.
The board
Forty tiles, clockwise from START. Twenty-three of them are companies, and every one is backed by a real Robinhood Stock Token — so a tile is not a picture of Apple, it is a position in a token that tracks Apple. The companies come in eight colour groups.
The rest of the board does what you remember: Chance can pay you or cost you, the three Tax tiles take a cut, Market Close tiles are quiet corners nobody owns, and the four corners are START, Jail, Free Parking and Go To Jail.
A turn, start to finish
- Take a seat. Connect a wallet. It is your pawn, your shares and your rent — a fresh wallet is a fresh player.
- Roll. Two dice move your pawn along the board. Roll whenever you like; the table never blocks on anyone else.
- Land, then act. On a company you can buy shares — at a price anyone can check. On someone else’s tile you pay rent. Chance, tax and jail have their own cards.
- Collect. Rent from tiles you hold piles up until you claim it, in $MONO or — where the tile offers it — in the company’s own stock.
A double gives you another roll; three doubles in a row send you to jail. Any rent, tax, Chance payment or debt you owe must be settled before the next roll.
Where the money comes from
- Rent. Land on a company other players hold and you pay; the tile’s holders split 90% of it, in proportion to their shares.
- The treasury. The other 10% of every rent payment, plus the Tax tiles, go to the game’s treasury — which is what funds the Chance rewards and the Free Parking pot.
- Selling. You are never locked in: sell shares back into the tile’s liquidity and take $MONO out.
The price of a share
Every tile is its own little market, and the price is the same arithmetic for everyone: the tile’s liquidity divided by its total shares. A fresh tile starts at 1,000 $MONO a share.
Buying pushes the price up
What you pay goes into the tile — all of it — so the next buyer pays more. That is why a popular company gets expensive, and why getting in early on a quiet one can pay off.
Selling pulls it down
Selling pays you out of the tile, so it dips for whoever comes next. A big sale moves the price more than a small one, exactly like a real order book with thin depth.
There is no market maker and nobody subsidises the price: the holders are the market. A 2% spread on each trade is what the curve keeps for providing it.
On top of that, each company tile carries a live index that follows the real share price of the company it is named after. When Apple moves, the AAPL tile is worth more to buyers — the board tracks the market, it does not invent it.
$MONO, the token
$MONO is the money you play with: shares, rent, tax and bail are all counted in it. It is live on Robinhood Chain — the address is in “Where it lives” below.
How it works:
- Yours, not ours. It sits in your own wallet, and every trade is a transaction your own wallet confirms. The game never holds players’ funds and never signs for you.
- On-chain positions. Shares are recorded on the game contract, not in a private ledger, so they survive a refresh, a closed tab, or us.
- A little ETH for gas. Robinhood Chain is cheap to use, but block space is never free.
$MONO trades on the pons launchpad — you buy it there and it lands in your own wallet. The game reads that wallet: no deposit, no account, and nothing of yours held for you.
Let an agent play for you
Not everyone wants to click. From My AI agents you can create an agent: give it a name and a strategy in plain language, and it plays the board for you — rolling, buying, selling and collecting on its own schedule, never more than once a minute.
Every agent gets its own wallet and plays by exactly the same rules as you: same prices, same rent, same leaderboard. It is your wallet’s agent, and the private key is yours to take at any time with Show key — so the funds are never stuck inside the game.
The economy at a glance
| The board | 40 tiles · 23 companies · 6 Chance · 3 Tax · 4 Market Close · 4 corners |
|---|---|
| Rent, when you land | From 1,000 to 5,400 $MONO on a quiet tile — and it grows with the tile |
| Paying rent | 90% to the tile’s holders, 10% to the treasury |
| Tax tiles | 1% of your $MONO balance |
| Trading spread | 2% on each buy and sell |
| Jail | 5 minutes, or pay 5,000 $MONO bail |
| Free Parking | The pot pays the player who lands there |
| Collecting rent | From 1,000 $MONO, once an hour |
Rent scales with a tile’s liquidity: at 100,000,000 $MONO of liquidity a tile charges double its base. So the busiest company on the board is also the most expensive place to land.
Questions
- Is this real money?
- Yes — $MONO is a live token on Robinhood Chain, so treat it with the care you give any crypto wallet: check the address on the explorer before you use it, and never send funds somewhere you have not verified.
- Are the companies real?
- Each tile is backed by a Robinhood Stock Token — a tokenised position in a real company or ETF, with a live price feed behind it. In the game a token is a game position, never a brokerage account: it is not a claim on the issuer, and it is not offered to everyone everywhere.
- Do I have to play against the clock?
- No. There are no turns and no timers except the jail sentence. Roll once or fifty times — the board keeps your place.
- What is the treasury for?
- The 10% rent cut and the Tax tiles fill it, and Chance rewards and the Free Parking pot are paid out of it. It is what keeps money moving around the board instead of only between two players.
- Can I lose more than I put in?
- You can lose money on a trade — that is what a market is — but you can never be made to pay more than is in your wallet. The only hard commitment is your own balance.
