How Griddy works

A round is a five minute window, and it runs the same way every time. Bets are taken for the first ninety seconds only. When that window shuts, prices are written down and your basket is measured against them for the remaining three and a half minutes. Then the bell, and the pool is split on chain.

1. Open. The grid is published and betting opens. The countdown on the play page is counting to the lock, not to the bell.
2. Lock. Betting closes and the opening price of every ticker is written into the contract. Nothing about your basket can change after this.
3. Bell. Closing prices are written, every basket is scored, and the pool is divided. Winners claim from their profile.

Because the betting window is a fifth of the round, two people who want to play together have to place inside the same ninety seconds. A round nobody joins does not settle - see section 10.

Every round publishes the same grid to everyone: nine to twelve tickers, drawn from one of two sets depending on the hour.

• Stock round. Tokenised equities, while the exchange is open. Quotes come from a market data feed.
• Meme round. After hours, when the equity feed has nothing new to say, the grid switches to the majors among memecoins, priced off a public exchange ticker. The badge on the play page always says which of the two you are looking at.

A ticker with no live price is dropped from the grid before the round opens rather than carried into it dead. If too few survive, the round is not opened at all - a basket cannot be scored against a price that was never there.

Pick between one and five tickers and give each a weight in steps of ten percent, adding to exactly one hundred. That is your basket. One ticker at 100% is a bet; five at 20% is a hedge, and it is a real choice rather than a difficulty setting.

Your basket return is the weighted move of its parts between the lock and the bell. Fifty percent of something that rose 2% and fifty percent of something that fell 1% is a basket that rose 0.5%. Nobody sees your picks until the round is over.

Stakes are in $GRIDDY, between 10 and 10,000 per basket. The first bet from a wallet asks for two signatures - one to approve the token, one to place - and every bet after that asks for one.

You can withdraw entirely while betting is still open: exit returns your whole stake, rake included, and takes your basket out of the round. Once the lock happens that door is shut, and the basket is in until the bell.

Both the lock price and the close price are averaged over roughly the last twenty seconds before they are written, not sampled at a single instant. A round is short enough that one printed trade at the wrong moment would otherwise decide it.

Both sets of prices are stored on chain with the round. Anyone can pull them back out and recompute every basket in it, including yours, without asking us for anything.

Griddy is parimutuel. There is no house on the other side of your bet: every stake in the round, minus rake, is one pool, and the pool is what gets divided. That also means the game cannot lose money on a round, and cannot be tempted to want you to.

Baskets that finished green take shares proportional to stake × how far they moved. A basket up 2% earns ten times the share of one up 0.2% at the same stake. Baskets that finished flat or red score zero and leave their stake in the pool.

B was right about direction on nothing and pays for it; A was more right than C and is paid more than three times as much on an identical stake. If nobody finishes green the pool is not kept - it carries forward whole into a later round, on top of that round's own stakes.

Rake is taken from your stake when the bet is placed. The base is 5%, and holding the token lowers it:

A quarter of every rake goes to the reserve that pays streak bonuses; the rest goes to the treasury. Rake never leaves through a back door - the contract caps what the treasury can withdraw at what the treasury actually accrued, and the owner cannot touch stakes.

Play a round and finish green, and your streak grows by one. Each step adds a small multiplier to what you are paid, up to a ceiling of ×1.5. Finish flat or red and it resets to zero.

Sitting a round out breaks it as well - unless you hold streak insurance. It is bought with $GRIDDY, the payment is burned rather than pocketed, it covers exactly one missed round, and there is a weekly limit on how many you can buy.

The streak bonus is paid from the rake-funded reserve, never from the round pool. Your streak cannot cost another player anything - it is not a share of their stake.

Every settled round credits a small $GRIDDY play bonus to each wallet in it, whether the basket finished green or red, capped per wallet per day and paid out of a separate Play-to-Earn reserve for as long as that reserve lasts. It is claimed from your profile whenever you like; it does not expire while the reserve holds.

Two things can stop a round from settling, and both are handled in the contract rather than by anyone's goodwill.

• Not enough players. A round needs a minimum number of baskets before it is allowed to lock. Below that, it does not settle and it does not cancel: it rolls into a fresh window with every stake and basket exactly where it was. That is why a countdown sometimes starts over. Your stake is untouched and you can still exit.
• Nobody closes it. If the operator ever stops - out of gas, off the network, gone - anyone at all can cancel the round after a grace period of thirty minutes past its close. Cancelling refunds every stake in full, rake included. No key of ours is needed for that, which is the point of it.

Nothing here has to be taken on trust. The game and the token are two contracts on Robinhood Chain, and every round, price, basket and payout is a transaction against them.

The token is fixed supply, minted once at deployment. It has no mint function, no faucet and no owner - not even we can print more of it. The game holds its token address as an immutable, so the asset you are staking cannot be swapped underneath you; pointing the game at a different token would mean deploying a different game.

Round history shows the same data this page describes, read back off the chain rather than out of a database.

A five minute game is easy to play a lot of without noticing, so the guardrails are part of the contract rather than a page in the settings.

• A hard cap on how many bets a single wallet can place in a day, enforced on chain where no interface change can route around it.
• A reminder in the bet panel, carrying your own count, once you have played a lot today.

These exist to protect you, not the house - the house has no position in your round. The grid resets every five minutes and it will wait for you.

$GRIDDY is the game's stake currency. You need it to enter a round, holding it lowers your rake, and it buys streak insurance. That is the whole of its utility, stated plainly.

It pays no yield, no dividend, no staking reward and no share of revenue. Its market price moves, so what your stake is worth can change between one round and the next. Playing is risk, the game is not available in restricted regions, and nothing on this page is investment advice.
