Robinhood Chain
You can't order a hashbrown. You fry one.
A browser game with pixel hashbrowns that live inside one contract. To get one, your computer makes millions of quick random guesses until one wins, and the winning guess decides its shape, crisp, hat and whatever it's holding. The first 1,000 are free, and after that they start at 0.001 ETH. Every order and every resale fills the Happy Hour meter, and when it's full, five orders are on the house. Combine hashbrowns into Jumbos, Family Sizes and Party Platters to get an edge when Happy Hour hits.
01 · The fryer
Fry a hashbrown
Press Start frying and your computer starts guessing. Every guess has the same tiny chance to win, so it's like rolling dice millions of times: sometimes you win in seconds, sometimes it takes longer. When a guess wins, your wallet asks you to confirm and the hashbrown is yours. If someone else wins first, a new round starts on its own. Keep this tab open while you fry.
It takes about 4.2M guesses on average.

02 · Your kitchen
Combine, boost, or toss
Combine two hashbrowns of the same size into the next size up. The one you pick first keeps its number, its special and its badge, and grows; the other is gone for good. Bigger sizes and specials earn Happy Hour points, and points mean you need fewer guesses to win a free Happy Hour order.
Combine
Pick two hashbrowns of the same size.
The dumpster
The pot buys back leftovers: any regular-size hashbrown that was paid for when it was mined and has no special or badge, for half of its original mint price. It's burned on the spot. Pot right now: —.
The offer is set when a hashbrown is mined and never changes. It's half of what the miner paid, not what you paid: a hashbrown mined for 0.01 ETH gets 0.005 ETH from the dumpster even if you bought it for 0.03 ETH on a marketplace. Hashbrowns mined for free (the launch and Happy Hour), specials, badged and combined hashbrowns can't be tossed, whatever anyone paid for them later.

03 · Employee of the Shift
Who's running the fryer?
Whoever fries the most hashbrowns in a shift of 1,000 is Employee of the Shift. When the shift ends, they pin a badge onto any hashbrown they hold, and it becomes part of that hashbrown's art for good. It's just for bragging rights. On a tie, whoever got there first keeps the spot.
Shift 1 standings
Last shift's badge
The first badge is awarded when shift 1 ends at 1,000 hashbrowns.
05 · How it works
How frying works
Guess
Your computer mixes a random number with your wallet address and the last hashbrown made, and scrambles them into a code. It does this millions of times, looking for a rare winning code. Your address is part of every guess, so nobody can copy your win, and the last hashbrown is too, so nobody can guess ahead of time.
Claim
When a guess wins, the site sends it to the contract, which checks it in an instant. If nobody beat you to it, the hashbrown is yours. If someone did, everyone starts a new round.
Keep
Your winning code decides what your hashbrown looks like: shape, crisp, toppings and what it's holding. The contract draws it from that code the same way every time, forever. No server, no upload.
A gentler kitchen
The whole first shift is free: the first 1,000 hashbrowns cost only the network fee, including shift 1's special and badge.
Paid orders start at 0.001 ETH and rise a little with every order: still under 0.003 ETH at #3,000, about 0.008 at #5,000 and about 0.1 at #10,000. No sudden jumps.
There's no cap on how many can be made. Prices rise, and each hashbrown takes about 10% more guesses every 1,000, and that's what slows the game down over time.
Part of every paid order, plus every resale royalty, goes into the pot, which pays for free Happy Hour orders and the dumpster. That share starts at 10% and grows to 20% by #10,000. The rest keeps the kitchen running (see the fine print).
Think of the pot as a jar with a line drawn on it. The line sits at ten times whatever an order costs right now. Two things drip into the jar: part of every paid order and the 5% royalty from every resale. An order's share starts at 10% of its price for the first paid order and grows a little with every order after it, reaching 20% at #10,000 and staying there. When the drips reach the line, the next 5 orders are free for whoever mines them, and the line is redrawn for the next round.
At the launch price of 0.001 ETH the line sits at 0.01 ETH, which is about 100 paid orders, or 0.2 ETH of trading, or any mix of the two. Nobody is paid for a free order, the kitchen included: they simply cost nothing. The banner at the top of the page shows how full the jar is.
If you paid for an order since the last Happy Hour, you need half as many guesses to win a Happy Hour order.
Jumbo 1 point, Family Size 2.5, Party Platter 6, any special +25. The more points you hold, the fewer guesses you need in Happy Hour: 1 point makes it 1.25× easier, a Party Platter about 1.6×, a special 2.25×, and 3× at most. Points that arrive by transfer wait an hour before they count.
The pot buys back plain, regular-size hashbrowns that were paid for when mined, for half of their original mint price, and burns them. Resale prices don't count: a hashbrown mined for 0.01 ETH always gets 0.005 ETH.
The game aims for one new hashbrown about every 30 seconds, however many people are playing. After every 16 hashbrowns it checks: if they came faster, winning takes more guesses (up to twice as many); if slower, fewer. It never gets easier than the normal starting level for that point in the game.
Each hashbrown you win makes your next one take twice as many guesses. That extra wears off one step every 30 seconds. It only affects you, so one fast computer can't take every hashbrown, even in Happy Hour.
If nobody wins a hashbrown for 10 minutes, the number of guesses needed drops back to the normal starting level for that point in the game, so the game never gets stuck.
Sizes
Two of a size make one of the next. The sticker counts the regular hashbrowns inside.
The late-shift menu
Some traits only turn up once the kitchen has been open a while. Once a trait unlocks it stays on the menu, so hashbrowns from later shifts can be things the early ones never can.
A special every shift
One one-of-one is drawn in every shift of 1,000, for as long as the kitchen stays open. The odds climb as the shift goes on without one, so if none has dropped, the shift's last hashbrown is guaranteed to be special. The first twenty are named and below, covering the first 20,000 hashbrowns (unfixed traits use sample rolls). After that, every shift still crowns a numbered special, drawn in one of the twenty one-of-one colourways with its own shape, hat and held item. The art is fixed at launch and can never be changed by anyone.

Plain-language terms
- Hashbrowns is a game and a digital collectible. It is not an investment, and nothing on this site is financial, legal or tax advice.
- Holding a hashbrown earns nothing. There are no payouts to holders. Happy Hour gives free orders to whoever mines them, and nobody promises you'll get back what you spend.
- The kitchen keeps 90% of each paid order, falling to 80% by #10,000. The rest, plus resale royalties, goes into the pot. The pot pays for nothing but the dumpster, and nobody can withdraw it, including the kitchen. Happy Hour orders simply cost nothing.
- The dumpster pays half of an eligible hashbrown's original mint price, never what anyone paid for it later on a marketplace, and only while the pot holds enough. If you buy a hashbrown for more than its mint price, the dumpster gives back far less than you paid. It is a way to leave, not a price floor or a promise of value.
- The kitchen can pause new orders and lower the royalty (never above 10%). It can't change prices, its cut, the rules or the art, can't mint without mining and paying like anyone else, and combining and the dumpster work even while orders are paused.
- Combining burns a hashbrown for good, including any special or badge it wears.
- Traits and specials are random and set by the contract. Nobody, including us, chooses what you get, and there's no guarantee anyone will want to buy your hashbrown later.
- Blockchain transactions are final and cost gas. Only spend what you're comfortable spending on a game.
- Make sure playing is allowed where you live. Don't play if it isn't.
- Hashbrowns is independent and not affiliated with any restaurant.
