Frequently Asked Questions

Q: How do I register?
A: First you need to make sure you have created a WCA account. You can do this by going to the sign-up page and creating an account. Once you have created the account and confirmed your email address, follow the menu bar to the Register page and follow the instructions fully and carefully.

Q: Why am I not on the registration list yet?
A: Please make sure that you have followed the instructions listed on the Register page. You could also be on the waiting list. The competitor limit can be found on the General Info page, and you can see the number on accepted competitors on the Competitors page also on the menu. If you have done everything correctly and the competition is not full then just be patient. We have to manually approve registrations and the organisers aren't available all the time. If you believe you have followed the steps correctly but still are not on the registration list after 2-3 days, then feel free to email us at the contact link on the General Info page. You can contact us at any time to check your place on the waiting list as well.

Q: I am no longer able to attend, what do I do?
A: The first thing you need to do is tell us as soon as you know via the contact link on the General Info page. Competitions generally fill up quite quickly and letting us know that you can't attend means we can add someone from the waiting list.

Q: If I do not attend do I get a refund?
A: If you inform us you are no longer attending before the limit date for refunds on the General Info page then you will receive a 75% refund. If this time has passed then you will receive no refund.

Q: How fast do I have to be to compete?
A: We recommend that you check out the Events and Schedule tabs - if you can make the time limit for the events you want to compete in, then you're fast enough! Loads of people come to competitions just to beat their own personal bests, and meet likeminded people, with no intention of winning or even making it past the first round.

Q: Are there different age categories?
A: All competitors compete on the same level and all ages are welcome. In general most are aged 10-20 but we have plenty of regulars who are older or younger than this!

Q: Do I use my own cubes to compete?
A: Yes! Make sure to bring cubes for all events you are competing in and look after them, you don't want them to go missing.

Q: Am I allowed to bring a guest?
A: Yes, you are allowed to bring as many guests as you please. Space in the venue may be restricted during busy times so please be sensible.

Q: Can I come only to spectate?
A: Yes! However, the venue is usually quite busy during the morning, so if you are just coming to spectate please come in the afternoon.

Q: I'm a parent, what can I do to get involved?
A: If you're looking for something to do then you can certainly help out with the running and judging! We pretty much always need help with this and they are really easy procedures to follow. You can come to the introduction to competing where we go through all of it there, and there is a tutorial on the Important Information tab as well. Running is also great for step count and requires zero knowledge of cubing if you're worried about that!

Q: When do I arrive at the competition?
A: If you are a new competitor, we highly recommend that you show up for the introduction to competing which is held as the first thing on both days. Otherwise, we recommend you turn up at least 15 minutes before your first event, you can check when this is on the Schedule tab. This will give you enough time to register, find a seat, and warm-up.

Q: Do I have to be there on both days?
A: No, if you're only competing events on one of the days, you don't have to turn up for the other day. You can see what days your events are on on the Schedule tab. If you are assigned tasks (running/judging/scrambling) on a day you're not competing on, do not worry about missing them.

Q: What do I do when I arrive?
A: The first thing you do when you arrive is find the registration desk if registration is open. If you arrive before registration opens, we will make an announcement as to when it does open. If there is nobody present at the registration desk then find a staff member and we will make sure to register you.

Q: When can I leave the competition?
A: You are more than welcome to leave whenever you want. If you have no more events left then you are not required to stay.

Q: How do I find results?
A: All the results will be found on this page a couple of days after the competition, once they have all been checked and uploaded. If you are looking for live results, in the Menu Bar at the top go to Results ≫ WCA Live.

New Competitors

If you are a new competitor, it is important that you are familiar with the Regulations. The regulations are very long and are quite a lot to take in so don't worry if you don't remember it all! Because of this, we have a video that explains the competing procedure which we recommend to watch before attending: Competing Tutorial. We will also be holding a tutorial for new competitors which we recommend you attend as well.

New competitors must bring some form of ID to show at the competition to confirm the name, the country they wish to compete for, and the date of birth registered with. The usual items of ID that people bring are Passports, Birth Certificates, Driver's Licenses, etc. As long as it has your name, date of birth, and country, then it will be fine.

If you have any questions, we recommend that you check the FAQ in case it has been asked before. But you are more than welcome to contact us at the link on the General Info page. We also recommend you check out the UKCA tab to sign up to our mailing list for announcements of future competitions, among other things.

Information for All Competitors

  • Schedule Changes: Please note that the schedule is subject to change up until the Wednesday before the competition, when we will know exactly how many people are competing in each event. These should be only minor changes and may involve increasing the number of rounds for some events!
  • Please help judge! As a competitor, your judging assignments are the absolute minimum you should be doing to help out. As second rounds, third rounds and finals have no assigned judges, we really need people to help out whenever available for these. If you are directly asked to judge, please go and judge for the remainder of the round in progress. If you do not comply then we are within our rights to disqualify you from the competition as per Regulation 1e2. If you're a parent you can also get involved with running and juging, it's really easy! We will have a judging tutorial in the mornings as well, which will run through the process and will be tailored towards parents who want to get involved.
  • Please note that Carbon-Fiber puzzles are not permitted, and please make sure your cube complies with logo regulations!
  • When you are competing and have handed in your puzzle, please make sure to be waiting in the designated area so that judges and runners do not have to come searching for you.
  • Please DO NOT talk about the scrambles or your solutions whilst the round is in progress as per Regulation 2g3.
  • During blindfolded events, please stay silent within the venue. These events require a high amount of concentration and any noise can be distracting. We will announce when the silence will begin and when you may talk within the venue again.
  • No flash photography under any circumstance within the venue. It is extremely distracting for competitors.
  • If you are a spectator, please stay 1.5m away from competitors at all times as per Regulation 7b. If you are filming someone competing, please keep out of the competitor area.
  • Please treat the venue with respect, put all of your rubbish in bins, black bin bags, or take it home with you and keep your area tidy.
  • There are thousands of puzzles at these events, make sure to keep yours together so you don't lose them! Keeping them in a bag and looking after it at all times is recommended. If you do lose a puzzle, please contact us at the link on the General Info page, it is likely that someone has handed it in to us.
  • We will be taking videos and photographs of the competition and the environment for our social media pages and website. By attending the competition as a competitor or a guest, you are accepting that you may be filmed or photographed for these purposes.


The venue is located in The Diamond Building on Leavygreave Road, next to Jessop Building. It is a rather unique building with a fascinating exterior so it's not difficult to find once you are on campus. The south entrance faces Leavygreave Road, and to find the west entrance you must walk past the left side of the jessop building, which is next to the Diamond. The Workroom used is on the left when you enter.


Car: Nearest car parks are mostly located on West Street, which is beside the University. Fitzwilliam Street car park (S1 4JL) and Eldon Street car park (S1 4GX) are only a short walk away (around 5 minutes). Q-park on Rockingham Street (S1 4NL) is also close, although more expensive.
Train: Sheffield Train Station is around a 20 minute walk to the Diamond, direct buses are limited early in the morning, although you can get the 218 bus from Paternoster Row and change to the 30 to get to the University of Sheffield. The venue is a short walk from here.
Plane: The nearest and most recommended airport to land is Manchester airport. From here, you can get a direct train to Sheffield.
Coach: The best coach/bus station to go to would be Sheffield Interchange, which is located opposite the train station. Meadowhall is a lot further out, although you can get the tram from here straight to the university.
Bus: Sheffield interchange would still be ideal if a long journey is made by bus. As for the city itself, the best bus links would be the 95, 95a, 52 or the 120, which go from the city centre to the University.


Recommended hotels are situated on Hanover way, both the Ibis budget and the Premier Inn are a 10-15 minute walk from the venue, or a 5 minute drive. There is also the Wilson Carlile Centre, which is much closer but is often busy on the weekend.

Each event is run in groups, depending on how many people are competing in the event depends on how many groups there are. We call each group up one at a time in order to complete their solves during the scheduled time for the round. We have software that automatically picks what groups you are in, the judges, and who scrambles for each group. This is the minimum amount you should be helping out as it only is for first rounds. We always appreciate extra help!

Please note down which groups you are competing and scrambling in before arriving at the competition!
