The field guide

How it works

One arrow, one castle, one falling gate. Everything below is the same rulebook the live console carries — pictures first, fine print one tap away.

Robinhood Chain Testnet — a test network, where the currency has no real value

This app is still in development and its wording has not had legal review. Nothing here is legal advice, tax advice, or financial advice.

01 A round in four moves

  1. Assault the castle

    Buy keys/shares

    Buy keys/shares by spending the network's own currency on a purchase from the contract.

  2. Take the top spot

    Current last eligible buyer

    Once that purchase confirms on chain, it is the current last eligible buyer — a temporary top spot that another eligible purchase can take.

  3. Portcullis-fall timer

    Time until round can end

    The countdown measures time until the round can end; a confirmed purchase can add time to that deadline.

  4. Round ends at settlement

    Round settlement status

    The round ends only when settlement confirms on chain; the contract alone decides the result.

That is the whole loop. The top spot is a temporary position, not a prize or a durable status — anyone may purchase after you, and this interface cannot keep it for you when the round ends.

02 Where the money goes

What each key price pays for
  • 65% Round pot
  • 15% Your faction's key holders
  • 10% Every key holder
  • 10% Protocol

A referrer takes 10% of the key price first (5% if they are in another faction), and the rest is split as shown. Taking the seat from another faction adds 5% of the key price, all of it to the pot.

What the pot pays when the round ends
  • 65% The final ruler
  • 25% The winning faction — shared by eligible key weight
  • 10% Seeds the next round

Unclaimed payouts roll into a later round's pot after 90 days. The contract decides the result; nothing in this interface does.

03 Seven things that can cost you

Each heading is the whole risk. Open one for the detail.

You can lose everything you spend

Whatever you spend here can be lost in full. Nobody can reverse a confirmed transaction, there is no refund route and no insurance, and this interface has no way to recover an amount once it has left your account. Treat any amount you spend as an amount you may not see again.

Taking the top spot does not make you the final eligible buyer

The current last eligible buyer holds a temporary top spot, not a prize or a durable status. Anyone may purchase after you, the contract decides which purchases count, and nothing this interface shows or does can hold the position for you.

A pending transaction can fail, be replaced, or land late

Once submitted, the Robinhood Blockchain decides the outcome — not you, not this interface. Your transaction can revert, be replaced by another from your account, or confirm long after the state you based it on has changed (including the last eligible buyer, cost, or countdown). Network fees apply whether it succeeds or fails.

The battle you watch does not decide anything

The siege is drawn from confirmed chain events after they have happened. No animation, camera angle, faction, sound or timing in this interface has any effect on what the contract does. Nothing you do in the 3D scene is an action, and no visual exchange is won or lost financially.

Congestion and ordering affect what happens

The network decides the order transactions land in; this interface does not. When the network is busy your transaction can be delayed or land behind someone else's, and automated participants can submit faster than a person reading a screen. That ordering can decide who holds the temporary top spot as current last eligible buyer when a round ends.

Past and estimated figures say nothing about later ones

Any historical figure or estimate here describes something that already happened, or a reading taken at one block. It is not a projection, not a rate of return, and not a statement about what any later round will do.

The laws and taxes that apply to you are yours to work out

Whether you are permitted to take part, and what you must report or pay where you live, is for you to determine — if necessary with professional advice. This interface gives no legal, tax or financial advice and cannot tell you whether taking part is lawful for you.

The contract itself could have a flaw

This contract has been reviewed by automated tools, not by a professional security firm. Code can contain bugs that let someone drain or break it. Treat the contract as unproven.

04 Four banners, one economic rule

Merry Men

woodland outlaws rallying under the Major Oak

Lincoln green, longbows, firelit camp under the Major Oak

Millers

market-town guild mustering around the Nottingham fair

Brass, banners, grain carts, populated fair stalls

Grey Friars

abbey keepers carrying alms through Sherwood

Abbey stone, stained-glass violet, persistent alms chests

Foresters

disciplined patrols guarding the greenwood roads

Oak staves, leather and rust, disciplined greenwood patrols

Verified contract rules: choose a faction before buying; the first faction a wallet selects in a round is locked for the rest of that round and resets when the next round opens. A cross-faction attack adds 5% of the current key price, while same-faction succession adds no levy. Settlement pays 65% to the final ruler, 25% to the winning faction pro rata by eligible muster, and carries 10% into the next round.

05 Every game word, and what it really is

The Last Arrow's words lead in the scene, but every one of them is a picture of a protocol concept. Each term below gives the plain-language label this interface is required to use, and the same pairing appears wherever a game term is shown — one tap on the term, and inline in anything you are asked to confirm.

Outlaw seated in the Sheriff's hallCurrent last eligible buyer

The temporary top spot: the address that a confirmed chain event most recently named as the current last eligible buyer. The scene shows that address as an outlaw seated in the Sheriff's hall at Nottingham. It is only ever what a confirmed event said: a purchase you have submitted but that has not confirmed never moves it, and neither does anything happening in the 3D scene.

Every confirmed purchase seats its buyer; there is no minimum beyond the key price. Whoever holds the seat when the deadline passes is the round's winner.

Assault Nottingham CastleBuy keys/shares

Buying keys/shares means sending ETH to the contract for one key. The scene presents that purchase as an assault on Nottingham Castle, an arrow loosed from the Sherwood treeline; what your wallet signs is an ordinary purchase call, and the amount the wallet shows is the amount that can leave your account.

Each purchase buys exactly one key at the current price, and you must choose one of the four factions. Taking the seat from another faction adds 5% of the key price, paid into the pot. You may send more than the price; the contract refunds the surplus in the same transaction.

Portcullis-fall timerTime until round can end

The countdown is the time until a round can end, measured against the deadline the contract reports. The scene draws that countdown as the castle's portcullis-fall timer. Between blocks the figure counts forward from your own device clock, so it is an estimate that can drift, not a reading from the network.

A round waits until its first key, which starts the opening timer. Purchases are accepted up to the deadline and the round can be settled the moment it passes; there is no hidden window after zero. The phase names (Greenwood, Raid, Torchlight, Hue and cry) are this interface's labels for time left, not contract rules.

Portcullis winched back upTime added after confirmation

Time the contract adds to the countdown when it accepts a purchase, which the scene draws as the portcullis being winched back up. It happens only once the purchase is confirmed on chain — a submitted or pending purchase has changed nothing about the deadline.

Every key after the first adds a scheduled extension that halves after a fixed number of keys. Once the extension is shorter than the endgame reset, a purchase only tops the deadline back up to that reset, so late purchases keep a round alive without banking time. There is no overall cap. This deployment's values are listed with its dials.

Castle vault beneath the keepCurrent round pot

The balance the contract holds for the current round. The scene shows it as the castle vault beneath the keep, and the vault's size is a presentation tier rather than a measurement you can read a number off.

After any referral reward, 65% of what is left of each key price goes into the pot, plus any cross-faction levy. At settlement the final ruler receives 65% of the pot, the winning faction shares 25%, and 10% seeds the next round. Anyone may also add ETH to a round that has not started; it buys no key and cannot be withdrawn.

Lengthening bowshotCurrent quoted cost

What a purchase would have cost at the one block the quote was read against, which the scene draws as a longer bowshot from the treeline. A quote goes stale: the cost can move between the block it was read at and the block your transaction lands in, and someone else's purchase in between is enough to move it.

The price starts at a fixed floor and rises by a fixed step for every key already sold in the round, so it resets when a new round opens. Because another purchase can land first, the purchase form lets you send a maximum above the quote; whatever the contract does not need is refunded.

Alms carried to SherwoodEstimated/claimable dividends

A share of every purchase paid to the people already holding keys in the round. The scene draws carts of alms leaving Nottingham for Sherwood, one for each share paid to holders.

After any referral reward, 10% of what is left of each key price is split among every key holder in the round and 15% among key holders of the buyer's faction, in proportion to keys held. You earn on keys you already hold, never on the key you are buying. Dividends are claimed, not sent to you, and a round's unclaimed dividends expire 90 days after it settles.

Swear to a faction bannerRound allegiance and faction-purse position

Choosing the one banner a wallet supports for a round. All four banners follow the same economic rule; names, looks and character are presentation only.

A faction is required to buy. Your first purchase in a round locks your faction until that round ends, and the next round starts clean. At settlement the final ruler's faction shares 25% of the pot in proportion to eligible keys. Keys bought in the short muster cutoff before the deadline count for everything except that share. If the winning faction has no eligible keys, its share seeds the next round.

Swear in a new outlawReferral reward

An address credited when someone who arrived through you makes a purchase. The scene calls it swearing a new outlaw into your band under the Major Oak.

A referrer earns 10% of the key price when locked into the buyer's faction this round, or 5% otherwise, taken before the rest is split. A referrer earns only if they bought a key this round or in the last few rounds, and naming your own wallet earns nothing. Referral rewards are claimed from the contract.

Last outlaw escapes into SherwoodContract-defined winner

When a round ends at settlement, the contract alone defines any winner; holding the temporary top spot does not itself decide that result. The escape into Sherwood that the scene plays is drawn after the fact from a confirmed chain event; it is an illustration of a result, never a cause of one.

The winner is whoever holds the seat when the deadline passes. They claim 65% of the pot, and the claim must be made within 90 days of settlement or it rolls into a later round's pot.

The King's men arriveRound settlement status

A round ends only at settlement: a confirmed on-chain event saying it ended. The scene draws settlement as the portcullis falling and the King's men riding into Nottingham. A countdown reaching zero on your screen is not settlement: until a confirmed chain event says the round settled, this interface says it is waiting for one.

Once the deadline passes, anyone may settle the round, and if nobody does, the next purchase settles it and opens the following round in the same transaction. Settlement opens every claim for 90 days; anything left unclaimed after that rolls into a later round's pot.

These rules are read from the deployed Robinhood Chain Testnet contract, whose values are fixed and cannot be changed by anyone.
