입장 시

`hello`, then a full snapshot of the arena.

The snake arena. Steering is a transaction, so the socket carries no input for it.

입장 시

`hello`, then the whole round: phase, time left, the commitment, every bet placed and every cash-out judged so far.

The curve. Bets are transactions.

입장 시

`hello`, then the cabinet: what is left, where each capsule stands, the machine's constants and every attempt being driven.

The claw cabinet, and the ONLY room whose gameplay input rides this socket rather than the chain - a transaction per frame is not a game.

입장 시

`hello`, then the machine: the bet ladder, the paytable, the meter and the spins still open.

The reels. A spin is a transaction; the socket watches it.

입장 시

`hello`, then the table: every cell's multiplier, the current snapshot, the line so far and the bets still standing.

The board. Bets are transactions; the socket has one verb, and it buys nothing.

입장 시

`hello`, then `stack`: every run being climbed with its rules state, the day's board and the rules' constants.

The tower. A start and every tap are transactions; the socket only listens, and says what the rules made of each tap.

입장 시

`hello`, then `derby`: the current and next race, recent history, the rules and the paddock.

The race. A bet is a transaction; the socket only listens, and every runner is one of the chain's own oracle feeds.

입장 시

`hello`, then `glide`: the day's board, every run in the air, the canyon cards and the rules.

The canyon. A start and every flap are transactions; the socket only listens, and the canyon it draws comes from a live price feed.

입장 시

`hello` alone.

The lobby. Somebody who has not chosen a game sits here, and it is counted in the socket total.

모양

{"t":"watch","account":"0x…"}

Says which account this socket is following, so the server can address one player directly - a refused join has to reach the person it was refused for. In the reels room it also arms that account.

알아 둘 점. It AUTHORISES NOTHING. The account is not verified, the contract decides who may play, and the address must match a 40-hex pattern or the message is ignored in silence.

모양

{"t":"ping","id":<any>}

Answered with `{t:"pong", id}`. The server also sends protocol-level pings and terminates a socket that stops answering them.

알아 둘 점. This is not the liveness mechanism the server relies on; it is the one a client can observe.

모양

{"t":"claim","tx":"0x…","secret":"0x…"} and three verbs after it

Takes the wheel of an attempt and drives it. The proof is a preimage: the hash of the secret must equal the seed the pull published on chain, so the only client that can drive an attempt is the one that made it - no signature, no challenge, no round trip.

알아 둘 점. None of the verbs carries a position, a time or a verdict. A wrong secret is refused and counted and never logged. A reconnect takes the wheel from the previous socket, which is told so.

모양

{"t":"quote", …}

Asks the operator to sign the price already printed in a square.

알아 둘 점. It carries no stake and no account, and the contract checks the clock, the lock and the float itself. A flood of them costs this process signatures and nothing else.

Params

none

반환

{ok, loop:{p50Ms, p99Ms, maxMs, windowMs}}

Liveness, plus the event loop's recent delay. Eight rooms, a physics step and every socket's fan-out share one loop, so a loop that stalls stalls every quote, every echo and every frame at once.

알아 둘 점. This is the figure that answers `the arcade is slow sometimes`. It is measured over ten-second windows and reset each time.

Params

none

반환

{ok, reasons, miniBlock, appliedMiniBlock, appliedLagMs, resyncing, lost}

503 when the socket to the node is down, or when the last APPLIED mini-block is more than five seconds old.

알아 둘 점. It measures what was applied, not what arrived. Measuring arrival meant a wedged dispatch chain answered 200 while no input had been applied for minutes, which is the exact failure this probe exists to catch.

Params

none

반환

{total:{playing, sockets, spectators}, arena, crash, claw, patch, trellis, stack, derby, glide, …}

The whole arcade in one object: a summary per game and three numbers for the chrome every page draws. `playing` means somebody with something at stake right now, and each game measures that its own way.

알아 둘 점. PUBLIC AND UNAUTHENTICATED, which decides what may appear on it. The crash summary withholds its point until the curve has stopped, and the claw summary carries the published commitment and never a link beneath it - one link is the outcome of the next pull nobody has made.

Params

none

반환

{supply, remaining, claimed, cells, price, pullsPerAccount, commit, chainLeft, blocked, machine}

The cabinet on its own, so a page can state what is left without opening a socket.

알아 둘 점. 503 when the claw room is not running.

Params

the pull id in the path

반환

one finished pull, whole

The seed the player published, every intent the server recorded, the tick the drop landed on and the verdict that came out of them - the arithmetic a reader can rerun.

알아 둘 점. A pull still being driven is a 404, deliberately: its trace is not finished and its link is not revealed. A revealed link is served only because the fulfilment that finished the pull already put it on chain.

Params

none

반환

{playing, watching, day, pot, top, leaders}

Stack's day without a socket: the UTC day, its pot in wei, the chain's own top three and the tallest runs this server has finished today.

알아 둘 점. 503 when the stack room is not running. The pot and the top three are read off the contract once a minute and after each finish, so they can trail a finish by a moment.

Params

the run id in the path

반환

one run, whole: {id, a, t0Us, startMini, taps:[{us, mini, hash}], results, height, why, finished, rules}

Every tap of a run with the mini-block that carried it and what the rules made of it - the arithmetic a reader reruns with arcade-server/src/stack.js to check the height the operator reported.

알아 둘 점. A 404 for a run this process never saw or has already let go of; it keeps the last five hundred. The chain still holds every tap, and the rules still apply to them.

Params

none

반환

{playing, watching, k, phase, card, unsettled, current, next, history, rules}

Derby's board for a page that has no socket yet: the current race and the next one, recent history, and the rules (the feed allowlist, the wall and night cards, the stake bounds and the seed).

알아 둘 점. 503 when the derby room is not running. `unsettled` counts bets still waiting on a settle, across every race this process still holds.

Params

the race number in the path

반환

one race, whole: {k, state, card, gate, line, runners, handicaps, pools, startPrices, startRounds, lineRounds, roundsFrom, scores, winners, why, hashes, bets}

The lineup, the handicaps, the rounds both seals named, the scores, the winners and every bet - the arithmetic a reader reruns with arcade-server/src/derby.js against the same public rounds.

알아 둘 점. A race this process never opened is a 404. `roundsFrom` says whether each end's rounds came from this room sealing them or were recomputed from the tape after a restart - the proof is the same either way.

Params

none

반환

{playing, watching, day, pot, top, leaders, canyons}

Glide's board for a page that has no socket yet, with every canyon's card alongside the day's pot and its leaders.

알아 둘 점. 503 when the glide room is not running.

Params

the run id in the path

반환

one run, whole: {id, a, feed, symbol, r0, sigma, startUs, startMini, startHash, answers, flaps, result, rules}

r0, the rounds of the canyon this run flew, and every flap with the mini-block that carried it - the arithmetic a reader reruns with arcade-server/src/glide.js `replay` to get the same score.

알아 둘 점. A run this process never saw or has already let go of is a 404.
