Underground Conference is a very special party, and so are its features and competitions. While the party itself could very well be regarded as satire on existing mainstream events, this doesn't mean it needs to suck. 

At this point we'd like to point out that cheating, hacking the voting system or handing in your entry into the wrong competition is absolutely welcome.


It's far too early to give you the timetable. Check back later, for example in 2022. Or now. As it's available now. Really.


Finally a real-life party to release all your amazing releases at. Fuck streaming. Experience your work on our bad-ass bigscreen with perfect sound system under the open sky.

While UC might be an event focussed on rather weird competitions, we all do appreciate serious art, too. 

Therefore the following old-fashioned compos will be held:

PC Demo
PC Combined 64k / 4k
Oldschool Demo / Intro (all platforms older than 20 years)
Pixel Graphics

We have more than enough music compos to pick from.



Invented for UC9, this turned out to be so fucking amazing at both UC9 and UC10 that we had to do it once more:

This compo is taking place on the private lake using boats provided by the organizing team.

There will be three teams (with one boat each) formed per round. Each team may consist of up to 4 people. Each member of the team may select one item of the below:

• Painting tools
• A massive supersoaker water pistol of doom
• Paddles

(Bonus: Everyone will receive a life vest as this lake is seriously “deep in the underground”)

The goal of the compo is to paint the best graphics entry on a canvas that is mounted to the boat.
To win, there are multiple strategies:

• Try to destroy other peoples entries using the super soaker
• Try to flee from other people trying to destroy your entry using the paddles
• Make sure you are the only one to actually have an entry
• Try to do all you can to protect your graphics artist from attacks

All entries that have survived afterwards will be judged by the audience, and the best one will win. 


This is the longest-running compo at Underground Conference, existing since back in 1995. Beat on an old pot with a stick. We will sample it and measure the BPM-Rate. You have to get as close as possible to 180 BPM and then stay there to win.

That's actually not at all easy.

PerfectPC is disqualified and banned from this compo, due to cheating at UC8. This means he is more than welcome to enter again.


Love is all around? Not so at Underground Conference. We want you to show your hate. All of it. Pick any demo/intro you really really hate, and screw it up. Replace parts, distort it, whatever. Just make really plausible that you really hate it.


Happy Hardcore used to be a non-mainstream kind of electronic music. Cheesy vocals, strings and pianos, combined with a hard beat at between 180 and 190 BPM. The dutch flavour of it often also contained break beats.

These days Happy Hardcore is typically called "UK Hardcore". This is because the dutchies went for Hardstyle (which is related) instead, where the UK guys kept it up for a couple of years, before the scene over there also mostly died.

Back when Happy Hardcore was close to what could be called "popular", a couple of commercial tracks from people like "Blümchen" or even (yuck) "Scooter" entered the charts. Create a music track that's better than that.

In case you need some reference, check out these mixes done by scamp. The best of audiophilicczyzs excellence combined with some seriously lacking mixing skills:


This is the compo most often underestimated by first-time UC visitors. The general idea is to hand in a really bad tune.
But as you'll learn, Shitmusic is a true art form.

No, it's not just a matter of not hitting the notes, or having a crappy beat, or tempo changes. To stand any chance against world-class record holders, you'll need to have all of that and far more.

"Just because you are bad at it doesn't mean you are good at being bad." 

Just so you know what you are competing against, here are a couple of tracks to use as a reference:

JCO - John Williams Rehersal With Professionals

Saga Musix - Music a Music remix Remix

Bundy - GoT in a Nutshell


Let's face it, music compos often are boring, especially if the music compo orga is corrupt, deaf, or both, and/or no pre-selection happens.

We'll have nature do the pre-selection.

You may hand in any track you've done, and we don't care if it's good or bad. However, it will only be played while and as long as you are executing any directions that your "creative drill instructor" is giving you, which typically is much worse than it may sound.

Due to the new compo name we will only allow OGG music files. GIF may be acceptable, too.


This competition one day used to be about doing headbanging on stage while some c64 SID track was being played. It escalated quickly from there, from people beating each other with ladders, over hurtful body slams, up to rather weird on-stage performances.

Basically, anything goes, as long as you are on stage and a SID song is playing in the background while you are doing whatever you believe to have to do.


Throw these bloody HDDs into the air! Due to a (very) long-standing tradition, measurements are done in Elitegroup member steps.

No SSDs allowed!

However, it has been a proven tactic in the past to try build catapults that then fail miserably. Rockets have also been done. You'll find your way to cheat through this compo again.


Well, this is not really a compo. However, due to the RULE card payment system, we can track how much you are drinking at the party. So let's make a challenge out of it: Try to impress your "friends" by drinking far too much alcohol just to become the top of the pops.

And in case you are wondering: The amounts on the picture here are given in LITERs, so don't believe this one to be easy to win.


Everyone loves it, so make sure not to miss this chance for a contribution. Create a module with your favourite tracker (mp3s are ok too, these days...). At the party you have to "support" your song live.

Either with your voice or with some weird instrument or whatever comes into your mind. Yes, penis enlargements do count as a musical instrument.


Nothing has changed. Life goes on as normal. Create a music track. Everything goes, absolutely no limitations whatsoever.

However, based on the incidence rate (organizers blood alcohol levels) the rules of this competition might have to be adapted before and during the party. This may affect the number of notes you are allowed to play at the same time. Depending on incidence rates we also may have to restrict the key your music is playing in, the minimum or maximum amount of BPM. We are always monitoring the situation closely, and might have to respond to local challenges individually.  

Update June 18th:

The incidence rate in Bingen has dropped to <10 per 100.000. Due to this, the track must contain the vocal sample at the beginning of Mark'Ohs 1995 prophecy "Drosten hörst du mich? (Long Version)'', either:
- in a recognizable form or
- if processed beyond recognizability, the mutation from original to your version must be made audible at least once (favorably an incidence during the 7th bar)
- Due to danger of high frequency lockdowns, the use of resonant 303-type sounds and instruments are strictly forbidden
- Exception: a mutation of above sample

Update June 25th:

Due to the current rise of the teenage mutant ninja corona variant and the fact that the queen sneezed three times in a row we have to announce the following adjustments to the Corona Regulations MUSIC Compo:

Minimum distance to Happy Hardcore: eight 'stampa' and/or 'stur ball' according to Leroy (Reference) and/or Scamp Happy Hardcore face (measured during the competition by RPi lab) ((read: no Happy Hardcore))
A first incidence of a 'Drosten hörst du mich?'-303 mutation during the 7th bar might positively affect the minimum distance to the Happy Hardcore restriction.


This is your regular Photo Compositing Compo. Create a composition of photos you have taken yourself.

Please note that due to the pandemic, we might have to restrict the number of elements there may be on the final picture. We may also have to restrict elements on the picture depening on what age group they are in. But do not worry, if there are any changes in these requirements, we will let you know well in advance, at the minimum 5 minutes before the new regulations are put into place. 

Update June 18th:

Since the world seems very gray to us due to corona, give your
picture an instagramable look that emphasizes the mood you want to

Also the following basic regulations now apply:

- all rule changes must be applied
- if you start at the party, you also have to follow the already
published rules
- we accept only jpgs
- upload will be activated only 24 hours before deadline
- send us only the final image

Update June 25th:

Studies have shown that the new mutant will only affect people and situations that are aligned at a vertical aspect ratio. Just to be sure we therefore have to ask you to crop your picture to 16:9.


This is a fast competition happening on-site. Everything is how you would expect from a graphics competition, however, you will be required to work with an upside-down Monitor we will be providing only.


Create a device or machine that is able to produce music. The device may NOT contain any kind of traditional loudspeakers. You may use things like dot matrix printers, floppy drives or whatever you come up with. It doesn't need to be something electronic however, you can also rock the stage with your self-made instruments of the analogue kind, eg. a digeridoo out of your old sink, a pan-flute out of milk cartons, or a guitar with strings made out of your granny's used floss.


We know it. You did have the idea for the best demo EVER. If only you would find the time to implement it... Well, now is your time to shine. Create an Audiobook where you describe your demo in full glory. Make us see it in front of our eyes, a great demoshock to brain. You may use your voice, and use any kind of audio effects to bring your point through.


You will be provided with a stitching board at the beginning of the party. You then have the week to create wonderful pixel art on that stitching board until the end of week.
