That's because the event code not entered doesn't exist or is otherwise invalid.

There's a checksum built into the string of letters so attempts to iterate them can be rejected without loading the database.

 

Neat, I didn't know that. What's the checksum?

Essentially just ID + SHORTHASH(ID, SECRET). So it's not so much a checksum as it's a signature. Just a very small one.

Ah, so you're not validating Eventlink codes; you're just checking whether it's a code that someone has made an event for on decklist.lol. I see.

Correct!

Eventlink, unfortunately, offers no way it integrate with it at all.

I've noticed that creating a tournament on decklist.lol seems to result in the date not "sticking" as I would expect it to. For instance, I created a test tournament and set the Tournament Date to 04/04/2026 during that process. However, after clicking the Create Tournament button, I can see that the Tournament Date has been set to 4/3/2026 in the Tournament Information panel despite my earlier input. Is this intended behavior?

That's probably a time zone thing maybe. Internally everything is stored as UTC, but then displayed as whatever your local computer is running. So when you enter 2026/04/04, it'll be 4th of april, at 00:00 in UTC, which is the 3rd in any timezone in the Americas.

It just need to not make any such conversion for the date field.

I'll fix that this coming week.

The issue where people in timezones significantly behind or ahead of UTC showing +/- 1 day on the date stamps, has now been resolved.

I used this for an RCQ at the weekend, searching for a less unwieldy method than mtgdecks. My local store is quite small so all magic events have to go through eventlink for store metrics to keep up our WPN benefits (or so i'm told).

For up to 32 players, decklist.lol seemed user friendly,marking checked decks is super helpful for minimisung paper notes. I have the following feature requests and/or notes:

1. Allow usually middle click operation to open a decklist in a new tab, currently it opens in the same tab regardless of click (left right or middle)
2. There is a warning section, is this meant for submissions warnings or mtg penalty warnings?
3. allow entry of final position (1st to 8th etc), leading into;
4. Allow export via API to mtggoldfish/mtgtop8/mtgdecks (appreciate this is a developer effort, but it's very helpful if you want to one-touch upload your results to one or more of thosee databases)

Either way, this is a great and very helpful tool for the judge working a smaller event solo, or a small team working with EventLink.
