Tokyo Challenge Winter A 2023


Information

コンセプト

スピードキュービングチャレンジでは、できるだけ多くの方々に自己記録更新へと"チャレンジ"していただくことを目指しています。

開催種目はいずれも3x3x3 キューブ (1ラウンド) のみです。

昨今のWCA大会では参加定員を大幅に上回る申し込みが寄せられ、参加希望者を十分に受け入れられない状態が頻発しています。
この状況を緩和するため、異なる地域で複数のWCA大会を同時開催し、総参加者数の増大をねらいます。
Go x Go Kyoto 2023、 Tokyo Challenge Winter A/B/C 2023のうち、ご都合の良いもの1つに申し込んでください。

WCAシリーズ大会

WCAシリーズ大会は複数の大会を一連のシリーズとして扱うもので、それらのうち一つにのみ参加できます。
複数に申込んだ場合は、申込完了日時が最も早いものだけを受理し、その他は無効となります。

Tokyo Challenge Winter A 2023(本大会 / 以下、A大会) 、Tokyo Challenge Winter B 2023(以下、B大会) (https://www.worldcubeassociation.org/competitions/TokyoChallengeWinterB2023) 及びTokyo Challenge Winter C 2023(以下、C大会) (https://www.worldcubeassociation.org/competitions/TokyoChallengeWinterC2023) はWCA シリーズ大会です。
A大会、B大会およびC大会のうち1つの大会だけに参加できます。

競技参加者以外の来場要件

新型コロナウイルス感染症 (COVID-19) 対策のため、本大会では会場への入場者数を制限しています。
当日飛び込みでの競技参加や見学はできません。

会場面積の制限、および感染症拡大防止のため同伴者及び見学者に制限を設けております。
未成年(18歳以下)及び配慮が必要な競技者一人につき一名の同伴者にご来場していただけます(無料)。
上記の同伴者以外の方で会場に来て見学されたい方(以下「見学者」)は有料(1,000円)となります。また会場の広さの都合上、見学者の入場を制限させていただく場合があります(原則として見学者は申し込み順で受け付けています。申し込み制限人数に達した場合は見学をお断りします。)

サポーター募集

より継続的かつ安定的にスピードキュービングチャレンジをするためには大会を成立させるための運営側に人手が必要となります。そこで運営に興味のある競技者や、競技者の保護者の方に「サポーター」として活躍していただきたく思います。サポーターの役割は大会当日の会場設営、受付、呼び出し、記録入力・印刷、机消毒、撤収作業等になります。サポーターご自身の競技やお子さまの活躍の応援に影響の出ない範囲内でご協力していただきます。
後日サポーターの募集のご案内をさせていただきます。

Concept

Speed Cubing Challenge aims to "challenge" as many people as possible to break their own records.

All events are 3x3x3 cube (1 round) only.

In recent years, WCA competition has received far more applications than it can accommodate, and it is frequently the case that there are not enough applicants to accommodate all of them.
To alleviate this situation, we aim to increase the total number of participants by holding series competitions in different regions at the same time.
Please register for one of Go x Go Kyoto 2023 or Tokyo Challenge Winter A/B/C 2023, whichever is most convenient for you.

WCA Series Competitions

WCA series Competitions are a series of multiple competitions, and you can only participate in one of them.
If you apply for more than one series, only the one with the earliest application date will be accepted, and the others will be invalid.

Tokyo Challenge Winter A 2023 (This Competition / hereinafter referred to as "Competition A"), Tokyo Challenge Winter B 2023 (Competition B) (https://www.worldcubeassociation.org/competitions/TokyoChallengeWinterB2023) and Tokyo Challenge Winter C 2023 (Competition C) (https://www.worldcubeassociation.org/competitions/TokyoChallengeWinterC2023) are WCA series competitions.
You can participate in only one of the A, B and C competitions.

Requirements for non-competitors

Due to the new coronavirus infection (COVID-19) control measures, the number of visitors to the venue will be limited.
No one will be allowed to enter the venue on the day of the event without any prior permission.

Due to the limited area of the venue and to prevent the spread of infectious diseases, there are restrictions on the number of accompanying persons and observers.
One accompanying person is allowed for each competitor who is a minor (18 years old or younger) or requires special consideration (free of charge).
Visitors other than the above-mentioned accompanying persons who wish to come and observe the event (hereinafter referred to as "visitors") will be charged a fee (1,000 yen). Due to the size of the venue, admission to visitors may be limited (in principle, visitors are accepted in the order of application. If the number of applicants reaches the limit, no visitors will be allowed.)

Supporters Wanted

In order to make Speed Cubing Challenge more sustainable and stable, we need people to support the event. Therefore, we would like to ask competitors and parents of competitors who are interested in supporting the event to become "supporters". The role of a supporter on the day of the event will be to set up the venue, reception, call-outs, input and print records, disinfect the tables, and clean up. Supporters are asked to cooperate within the scope that does not affect their own competitions or their children's competitions.
We will inform you of how to apply for supporters at a later date.
