International Asynchronous Rock Paper Scissors Tournament 2023


This tournament is an annual event with eight years of history. It all started when Sadale was bored right before the April Fools of 2015. The first event of this tournament was The International Asynchronous Rock Scissors Paper Competition. Unfortunately, due to lack of marketing and horrible user interface, we had only 23 players in the first event.

In the second year 2016, we try to reach out more players by making this event more like an international event. Similar to Olympic Games, we tried passing the host to different country in each year. With improved UI of the website, we managed to get 29 players! The event was hosted in Poland.

In the third year 2017, we've got a hoster from yet another country. Unfortunately, the hoster failed to setup the website on time. Therefore, the event was in hiatus.

In the fourth year 2018, the backend was were re-written with a microframework. A more human-friendly captcha were implemented. Sadale was the hoster of the event again. We managed to get 2 international supporting organizations for this year of the event. From this year on, we started issuing participation certificates to all of the participants of the event. There was 25 players.

To facilitate the setup of the website of this event, Sadale had dockerized the Flask webapp and released the source code. With the docker image, the event's website can be hosted by anyone easily!

Since 2019, the host had been passed to, which is an American organization. In addition, we managed to get 9 international supporting organizations for the event in 2019. In 2020, the number had grown to 14. Last year in 2019, we've got 219 players to join the event. For 2020 we had 158 people join us for a fantastic event! This year we have 12 supporting organizations and we're looking forward to have even more players to join us this year!

2021 and beyond! 2021 had only 65 participants a big drop on numbers sadly.... As for 2022? Well April FOOLS!!! We didn't have one. So for 2023 we hope to have record turnout to make up for it!! We have many new supporting organizations and new friends to share all the fun!!!

Why Joining This Event?

Certificate of Participation will be issued to all of the participants! Did I mention that the logo of the organizer plus all of the 11 supporting organizations will be shown on the certificate? That's 12 logos in total! Anyone seeing all these logos stamped onto the certificate would be super impressed! Show it to your friends and they'll be super duper envious! Don't quote us on that, but perhaps having this certificate may possibly grant you immunity against the coronavirus! So why don't you join it for this awesome certificate? :)
