Hectile

100 tiles. 100 companies. One board.

Own the most, run the board

Every tile holds a real share of the ETH / HECT pool. The Floor takes 2% of the ether in every trade and pays it to the Board, which divides it: 70% to the tiles, 20% to the sectors, 10% to the chair. Every tile is always for sale at the price its holder posted. Own a row, own a sector. Own the most, become chairman.

Rules of play

Taken from the header of the Board contract, which is the rulebook. Every number here is a constant in the code; nothing on the board has an owner who could change it.

4.1Object of the game

A board of 100 tiles in ten rows. Every tile is a company, and every tile holds a real share of the ETH / HECT pool. The Floor, the pool's Uniswap v4 hook, takes 2% of the ether in every trade and pays it to the Board. The Board divides it.

70% to the tiles: 0.7% of every trade's duty to each of the 100 tiles.
20% to the sectors: 2% to each of the ten rows, held as a pot.
10% to the chair: to the player who holds the most tiles.

Own a tile, earn its share. Own a row, win its pot. Own the most, become chairman.

4.2Contents

100 tiles, numbered 0 to 99. Tile t sits in row t / 10, column t mod 10.

One chair.
1,000,000,000 HECT, printed once. There is no mint function, so no more can ever be printed.
No banker. No owner, no setter, no pause, no upgrade path.

4.3On your turn

Claim a tile. Any tile, at any time, is for sale at the price its holder posted. You name the most you will pay, the price you will post, and a deposit. You pay the posted price in HECT, straight to the holder. Their unspent deposit goes back to them, and so does the ether the tile earned while it was theirs. An empty tile costs nothing to claim beyond the deposit.

Post a price. Prices are whole HECT, from 10,000 to 10,000,000. Post it high and nobody can take the tile cheaply, but you pay tax on it. Post it low and the tax is light, but anyone can buy you out at that price. That is the whole game. The ceiling is 1% of the supply, so no tile can be priced out of every other player's reach.

Pay the tax. 1% of your posted price per day, drawn from your deposit by the second, and burned. Nobody collects it. The deposit must cover at least one day when you claim, reprice or withdraw.

ExampleAt 10,000 HECT, the lowest price, the tax is 100 HECT a day. At 1,000,000 HECT it is 10,000 HECT a day, and at the 10,000,000 HECT ceiling it is 100,000 HECT a day. A deposit of 700 HECT on a 10,000 HECT tile lasts seven days.

Keep it up. Top the deposit up, withdraw what is above one day, reprice, rename your company, or abandon the tile and take the unspent deposit with you.

Lapse and foreclose. When a deposit runs dry the tile lapses. Anyone may foreclose it: the tile goes back on the board empty, and what it earned after the moment it lapsed goes to its sector's pot, not to its holder.

Collect. Collecting pays you the ether your tiles have earned, the chair's pot if the chair is yours and you have sat a full day, and anything owed to you from a buyout. Ether is only ever paid to the player it is owed to, and only when they ask.

4.4Sectors

A row's 2% builds up in its pot. So does the share of any tile in that row while it sits empty or lapsed. Hold all ten tiles of a row for 24 hours without a break and you may take the whole pot. The clock then starts again: hold another 24 hours to take what has built up since.

Losing any tile of the row, to a buyout, an abandon or a lapse, stops the clock at once. None of the ten may be lapsed when you take the pot.

The first pot a row pays holds everything that row has earned since the board opened, the shares of its empty tiles included.

4.5The chair

The player holding the most tiles is chairman and earns 10% of everything. The seat changes by itself when a claim puts someone strictly ahead. A chairman who loses tiles keeps the seat until someone holding more takes it. A tie keeps the sitting chairman.

A chairman is paid only after sitting a full day. Once seated for 24 hours they may collect the chair's pot whenever they like, and if they are unseated after that, what built up is credited to them first. A chairman unseated inside their first day is paid nothing: the pot stays where it is for the next chairman who lasts the day. That stops a seat taken for one block around a large trade from carrying off the chair's 10% of it. The pot from before the first chairman waits for the first chairman to last the day.

On this boardThe chairman's seat is drawn black with a gold crown, on the chairman's highest-priced tile. Every other tile the chairman holds carries a small crown.

4.6Limits, stated plainly

The tax is measured against the price posted, not against what the tile earns. A tile can cost more in tax than it earns. Price accordingly.
A holder can reprice at any moment, including just before your claim lands. The most you said you would pay protects you: if the price rose, your claim reverts and costs you only gas.
Anyone can buy your tile at the price you posted, at any time. There is no refusal.
Ether is booked to the tiles at the start of every move, before anything changes hands, so what a tile earned up to a buyout or an abandon goes to the player who held it.
A lapsed tile keeps its holder and its count until someone forecloses it. What it earned since it was last settled is split by time: the share before the lapse to its holder, the share after to the sector. The split assumes the ether arrived evenly over that stretch. A holder who collects often keeps the stretch short.
A posted price is only a real offer to a player who holds that much HECT.
The pool's liquidity belongs to the launcher. It is provided from the launcher's own wallet as a normal Uniswap position, and the launcher can withdraw it at any time. If the pool has no liquidity, it stops trading, and the Board stops earning.
Rounding always favours the board: tax rounds up, payouts round down.
The Floor's 2% is of the ether that crosses the pool, buy or sell. Against what you pay or receive, that is 2.00% on an exact-in buy or an exact-out sell, 2.04% on an exact-in sell and 1.96% on an exact-out buy. When ether is the side you named, it is on the amount you asked to swap, even if the trade stops at its price limit.
Before a claim, the Board needs your approval to move the HECT for the price and the deposit. The page asks for exactly that amount.

How the money flows

Every swap on the ETH / HECT pool pays 2% of the ether that crosses the pool to the Board. Each wei of that duty is split into exact shares of a trillionth of a wei, so the split never rounds against a player until the final payout.

70%

To the tiles. Each of the 100 earns 0.7% of all duty, paid to its holder, or to its sector while it stands empty or lapsed.

20%

To the sectors. Each row's pot takes 2%, paid out whole to a player who holds the row for a day.

10%

To the chair. The chairman's pot, paid once they have sat a full day: when they collect, or when the seat changes hands.

The tape and the scores

The pieces on chain

Three contracts on Ethereum mainnet and one pool. None has an owner. At launch the addresses will be printed here on hectile.fun and on x.com/HectileGame, and nowhere else. Check them against both before you approve anything.

The charter of the board

Hectile. One hundred companies. One board. No banker. The same words are carved into the header of the HECT contract, where nobody can edit them.

IThe board was always rigged

Every market you have played has a table you cannot see. Someone sets the fees. Someone keeps the house edge. Someone can pause the game when it stops going their way. You were never a player. You were the volume.

Hectile is a table you can see all of. One hundred tiles, drawn in the open, with rules written in a contract that nobody can edit. Not us. Not anyone.

IIEvery tile is a company, and every company pays

When anyone trades HECT, 2% of the ether moves to the board. It does not go to a team wallet or a treasury with a multisig. It goes to the tiles.

Seventy percent of that 2% is split across the hundred tiles, 0.7% of it to each, for as long as someone holds the tile. That is a share in the plain sense: a slice of the table's takings, paid in ether, to whoever sits in the seat.

IIIEverything is for sale, always

On this board, nobody gets to hoard in silence. Every tile carries a price, posted by its holder, and anyone may pay that price and take the tile. No bids to ignore and no offers to refuse. The price you post is the price you accept.

Post it high and you are safe, but you pay for that safety. Post it low and you pay little, until someone takes it from you. Each holder has to decide what their company is worth, and the market decides whether they meant it.

IVThe rent is burned

Holding a tile costs 1% of its posted price, every day, paid in HECT. Nobody collects that rent. It is destroyed.

Every day the board is played, HECT gets scarcer. The more the tiles are worth, the more burns. The game eats its own currency, and the only way to feed it is to play.

VRows are sectors, and sectors are power

Ten rows. Energy, Industry, Finance, Agriculture, Health, Technology, Media, Consumer, Transport, Property. Each keeps a pot that grows with every trade and with every tile left empty.

Own all ten tiles of a row, hold them for a full day against everyone, and the pot is yours. One tile lost, and the clock resets to zero. A monopoly here has to be earned in the open and held against the whole table.

VIOwn the most, run the board

The player with the most tiles takes the chair, and the chair takes 10% of everything the board is paid. It is not given, voted on or sold. It is counted.

A chairman who sits for a day is paid. A chairman who cannot hold the seat that long gets nothing. The chair belongs to whoever can keep it, not to whoever grabs it for one block.

VIINo banker

There is no owner. No admin key, no pause, no upgrade, no setter, no mint. The supply was printed once, one billion HECT, and it can only shrink. The rules in this charter are the rules in the code, and the code cannot change.

We did not build a platform. We built a board, set it on the table and took our hands off it.

VIIIThe only promise

Hectile promises you nothing but a fair game. Tiles can cost more in rent than they earn. Prices move. Every move costs gas. You can lose.

But you will never lose to a rule you could not read, a fee you could not see, or a banker who changed the game halfway through.

One hundred tiles. One hundred companies. One board.
Own the most. Run the board.
