What Does DNS Mean in Cubing?

DNS is Did Not Start

DNS stands for Did Not Start. In a WCA result, it means you were eligible for a particular attempt but did not start that attempt. It is a competition result label, not a judgement about whether you are prepared to compete or whether you should leave the venue. Think of it as a record of a missed or declined attempt in a round.

The important boundary is earlier than many first-time competitors expect: an attempt starts with inspection, not when you make your first solving move. If you take the scramble and begin inspection, you have started the attempt. Once that happens, an issue with the solve is not automatically a DNS simply because no turns were made.

DNS versus DNF: the practical difference

DNS and DNF are both non-time results, but they describe different moments. DNS applies when an eligible competitor does not start. DNF means Did Not Finish and applies when an attempt is disqualified or remains unsolved or unfinished. For a competitor, the easiest way to keep the labels straight is to ask one question: did my attempt begin with inspection? If the answer is yes, treat any incident as a started attempt and let the judge or Delegate determine the result.

This is why a late arrival, a decision to skip before coming to the station, and a disqualified solve are not interchangeable. A person who is not eligible for a later cutoff attempt has no result for that attempt; that is also different from DNS. Do not try to choose a label yourself to protect an average. State what happened, leave the puzzle and timer alone when appropriate, and ask the official running the station.

How DNS affects a round

For a Best of X round, both DNS and DNF are the worst possible result, so a started successful solve is usually much more valuable than a missed attempt. For an Average of 5, one DNS or one DNF can be the discarded worst result. More than one combined DNS and DNF result makes the average a DNF. For a Mean of 3, any DNS or DNF makes the mean a DNF. These rules are reasons to show up ready, not reasons to take risks with an unclear procedure.

A DNS-only round also has a special consequence: if you have no results or only DNS results for the round, no results are recorded. That differs from a visible DNF result after a started attempt. Because formats, cutoffs, and schedules vary by competition, read the event details on the official competition page before travelling and listen for your group when the round starts.

Examples that clarify the label

• You are called for an attempt, are eligible to compete, and decide not to come to the station. That is the kind of situation DNS describes.
• You take a puzzle and begin inspection, then the solve is disqualified. The WCA result framework treats a disqualified started attempt as DNF, not DNS.
• You miss a cutoff because your earlier results were not fast enough. You were not eligible for the later attempt, so you do not receive DNS for that attempt.
• You reach a time limit after inspection and the solve begins. The competition tutorial describes the resulting stopped attempt as DNF rather than DNS.

A calmer first-competition routine

The useful response to DNS anxiety is a simple arrival routine. Before the round, verify your group and event, locate the waiting area, have your puzzle ready, and be nearby before competitors are called. If you need to step away, tell a Delegate only when it is relevant and return early. The goal is not to memorise every regulation; it is to avoid creating an avoidable missed attempt.

At the station, let the judge lead the sequence. When they ask whether you are ready, confirm only when you are prepared to inspect and solve. If you notice a possible duplicate scramble, equipment problem, or other incident during inspection, do not make moves just to force an outcome. Stop, explain the observation briefly, and call a Delegate. Only a Delegate can award an extra attempt, so do not rely on an assumption from practice sessions or another competitor's story.

It also helps to separate a competition scorecard from your personal practice history. A practice timer can make it easy to rehearse arriving at the mat, starting an inspection, and committing to a calm solve, but it cannot decide an official result. At a sanctioned competition, the judge and Delegate work from the live scorecard and the current regulations. Use practice to make the routine familiar; use the officials and the current rules to resolve the result.

Use official sources when an incident happens

The WCA Regulations are the authority for the result definitions and format rules. The WCA Competition Tutorial is a useful companion because it explains the competitor-facing distinction in plain language: DNS is an eligible attempt declined before it starts, while a time-limit outcome after the attempt starts is DNF. Regulations can change, and a real incident can have details this article cannot cover. In the venue, pause and ask the WCA Delegate instead of arguing from a remembered rule.

For practice, rehearse the part you control: arrive when called, wait for the judge's sequence, use your inspection deliberately, and finish only after you understand the timer procedure. That preparation reduces missed starts without turning a competition into a rules test. Save the finer decisions for the officials who have the scorecard, the event format, and the facts of the incident.
