Happy late April Fool! It's that time of the year again. International Asynchronous Rock Paper Scissors Tournament 2020

This year we've managed to invite quite a few new supporting organizations. Of which a few of them are the serious ones, like the ones that's registered in real life or software that have significant influence in the internet. We're very glad to have them supporting our event this year. These supporting organizations include:

  • Dimsumlabs, a hackerspace located in Hong Kong, China
  • G and B, a cram school located in Saitama, Japan
  • Bitcoin Knots, a Bitcoin node software that's a derivative of Bitcoin Core with a collection of improvements

It makes the logo count of the participation certificate of this year 15! That's more than we ever had in the past years!

So you wanna have this certificate? Tsk tsk! Too bad! This event had ended and you can't join anymore. You have to wait for next year. :P

This year we've got 158 participants. I ranked 150th with a score of -160. That's my worst performing year. :(

Oh. At least I've got this awesome participation certificate that you don't get to have! :P

International Asynchronous Rock Paper Scissors Tournament 2018 - Site's up!

March 28, 2018, 12:28 p.m. Behind the Scenes Product Release RPS

Hey guys! It's that time of the year again! Our awesome Rock Paper Scissors Tournament will soon be commencing, and its website's ready! :-)

This is supposed to be an annual event. However, it didn't happen last year because the hoster failed to set up the site. Therefore, we're going to host this event on our own this year.

We'll be issuing certificate of participation of all of our participants! If you're looking for a degree or a job, certificates are proven to be helpful on building your portfolio. That's why we're issuing them! Put that in your resume and we promise that'd secure your job offer or degree offer!

This year we've also made the captcha easier than it used to be! We believe that it'll invite some bots to join our event. That'd make our tournament even more competitive than it was! :)

Event details:

  • Duration: 1st April 2018 00:00~23:59 UTC
  • Location: Internet
  • Participation Criteria: Anyone from any country
  • Website for the tournament:

Technical details

The front-end is almost the same as the old one. Semantic-UI were used. But we've changed the back-end from Django to Flask. Flask takes much less RAM compared with Django. And it takes much less efforts to develop stuffs using Flask, especially for trivial projects like this one. I guess Django is better suit for larger scale websites.

I guess I'll be opensouring this thing. But I'm too lazy to do so right now. Maybe later. :P

Asynchronous Rock Paper Scissors Tournament 2016 - End of Service of Poland Website

June 1, 2016, 12:04 p.m. RPS

Better to be late than never announcing it. The Poland Event website is closed.

The hoster could not pay for the hosting fee. Therefore, the site is closed about a month after the begin of the event.

Considering that the hoster is relatively young, he is a genius of being capable for setting up a website for the event.

Give a big hand to Eruverio! Our hoster/organizer of the RPS tournament 2016!

The facebook page of the event is still alive. And the website of the event is now archived at Wayback Machine.

We will definitely host another event next year! I'll probably find someone who is capable for keeping the site alive for at least a few years.
