Direct answer: you can usually tell — before you paste — by reading the wall card, not the code string. A card showing uses left is a live candidate; a greyed-out 0/30 card is finished; a listing that has vanished was most likely hidden after dead-code reports; and a code with no uses-left number at all cannot be checked, so pasting it is a guess. The honest limit is on the other side: no pre-paste check proves a code will redeem, because the wall's number is submitter-reported, not verified against Muse. This guide gives you the four-signal check, the verdict for each signal, and the limit you must not forget.
Run these in order. The first signal that gives a firm verdict ends the check — you do not need the rest.
If the code came from a wall card, it has one: a number out of 30, with a progress bar. If it came from a screenshot, a chat message, a forwarded note, or a frozen list, it has none — and that absence is itself the verdict: uncheckable, do not paste yet. Go to the wall, find the same code if it is listed, or pick a card that shows a number. A code without a number is not "probably fine"; it is a guess with no evidence either way, and guesses fail exactly the way a spent code fails. This is the single most common pre-paste mistake, and it is entirely avoidable: never paste a numberless code when numbered cards exist.
A card showing uses left (for example 14/30) is a live candidate: it has room, its copy button is live, and it is worth pasting — copied exactly from the card, never retyped. A card showing 0/30 is finished: the wall greys it out and disables its copy button precisely so you skip it. Do not paste a 0/30 code "just to be sure"; there is nothing left to redeem, and the check has already been done for you. How a code's count reaches zero — and why the total cap is the wrong number to watch — is explained on the uses-count page.
A code you saw yesterday that is gone from the wall today was most likely hidden after 3 dead-code reports, which removes it at once. Treat a vanished listing as dead, not as a glitch: do not hunt for the removed code on other lists, where it would be just as dead, and do not re-post it yourself. The fix is the same as for a 0/30 card — pick a code that is currently listed with uses left. (What happens to a code once its uses run out is covered on the runs-out page.)
A card at 1–3 uses left passes the check but carries a warning: other readers are redeeming the same card, and the number can hit zero between the moment you see it and the moment you paste it. With a low card, either redeem immediately or pick a fuller card. A low number is not a dead code — it is a code with a short fuse, and the mistake is treating it as if it will wait.
Example 1 — 14/30, paste it. Ana opens the wall, taps a card showing 14/30, and copies exactly from the card. The number is comfortably above zero, the card is currently listed, and the copy is exact. Verdict: live candidate. She redeems, and it goes through.
Example 2 — 0/30, skip it. Ben's eye lands on a greyed-out card with its copy button disabled. He does not paste it, because the wall has already told him the answer: finished. He picks the next card showing uses left instead, and saves himself a failed paste and a round of self-blame about typos.
Example 3 — Vanished, do not chase it. Carla bookmarked a code on Monday; on Wednesday it is gone from the wall. She assumes the site lost her bookmark and starts searching other lists for the same code. That search is wasted: the code collected 3 dead-code reports and was hidden. The correct move was a currently listed card, not a hunt for a removed one.
Example 4 — No number, a blind paste that fails. Dan pastes a code from a friend's screenshot. It fails as already redeemed. The screenshot gave him no number to check, so he learned the code was spent only by failing — the most expensive way to learn it. Had he checked the wall first, he would have seen either a live card to use or no listing at all, and either answer would have saved the paste.
This is the limit that keeps the check honest. The wall's uses-left number is reported by the person who submitted the code and adjusted when visitors mark "I Used" (one mark per visitor per code). It is not checked against Muse's own ledger, because the wall did not issue the code and cannot ask Muse whether it is still good. So a card showing uses left is a strong candidate, not a guarantee: it can still fail as spent, revoked, or mistyped. When that happens, the failure is no longer a pre-paste question — run the invalid-code diagnosis in order (typo, then uses, then account and window, then dead or revoked) and let it name the failure. And if a wall code fails, report it — one report per visitor per code — so the next person's pre-paste check gets better: a code hidden after 3 reports is a code nobody else has to waste a paste on.
Partly. A wall card's uses-left number, a greyed-out 0/30 card, and a vanished listing all tell you something before you paste — but no check proves a code will redeem, because the wall's number is submitter-reported, not verified against Muse.
It means you cannot check it. A code from a screenshot, message, or list carries no liveness information — pasting it is a guess. Pick a wall card with a visible number instead.
Treat it as dead. A code is hidden after 3 dead-code reports, and a removed code does not come back. Pick a currently listed code with uses left.
No. Any site that asks you to log in to "check" a code is running a scam pattern, not a checker. Real codes are strings you paste yourself into Muse's own redeem entry.
You know the check now: a visible number above zero, a listing that is still there, an exact copy from the card — and the humility to accept that even a live-looking card can fail. The wall below shows cards with their numbers visible. Pick one that passes the check, copy it exactly, and redeem it while your window is open.
