So you're new to the concept of a National Puzzlers' League convention, and you have questions. Let's pretend we know what they are.
For 2025, we'll be gathering in Minneapolis/St. Paul, Minnesota from July 17th through 20th.
The simple answer is that it's the best decision you will ever make in your puzzling life.
It's a four-day convention where many of the most puzzle-mad people in the world gather. Most of them are members of the National Puzzlers' League, the world's oldest puzzlers' organization. As members of this nonprofit organization, we've been solving puzzles nonstop since 1883. (Well, not the same people. But you get the idea.)
You'll see dozens of new puzzle types debuted at the convention. You'll play in a team-based puzzle-solving extravaganza and test your skill in a solving contest of wordplay puzzles. You'll play Jeopardy! and charades and many other games in ways you've never thought possible. You'll hear our program director WILLz and other famous puzzlers speak. You'll tour the city with your eyes wide open for clues. You'll constantly talk about puzzles. You might never sleep. As member Mosayc wrote in his post on Wired Magazine's Decode blog: "the annual conventions are lively and entertaining, deftly combining good conversation and puzzle-solving ... Sleep, you'll notice, is not on the agenda. There are 361 other days in the year for that sort of thing."
And you will meet the best friends you'll ever have. Going to an NPL convention was the first time many of us met people from all over the world who were just like us. As longtime member Eric put it, "This is where the people from your home planet are."
You don't have to be a member of the NPL to attend the convention. In fact, many people first learn about the NPL by showing up at the convention when we're in their home city and then decided to join. (We were in Dallas, Texas last year and we'll be in Bloomington, Indiana next year.) No, you don't have to join afterwards either, but you may find you can't help yourself.
That wasn't a question.
The NPL has a strong slant toward word puzzles, but at the con you'll see a tremendous range, including word puzzles, logic puzzles, trivia puzzles, competitive puzzles, collaborative puzzles, and one-of-a-kind puzzles, games, and puzzle games you've never seen before.
Saturday's Flat Competition, the highlight of the convention for some longtime krewe members, is all about flats, puzzles in verse form that have proven over our 120-plus years to provide endless opportunities for creativity and continuous solving enjoyment. We'll admit flats can be difficult for newcomers, but we don't want that to scare you off — they're just a small part of the convention. For some examples of flats, check out our minisample (PDF). The flat competition itself is designed to be friendly to newcomers. People can compete individually, in pairs, or join one of several large groups that solve cooperatively.
While the specifics vary from convention to convention, the official schedule usually looks something like this (This is not the real schedule — you'll find it right here when it gets close to con).
In addition, there are always unofficial games, walk-around puzzles outdoors, etc., during the day, and informal games and pencil-and-paper puzzles (all brought by attendees) well into the night. There are also two or three official cryptic crossword puzzles, released Thursday evening, which members pair up on and co-solve over the weekend. Also a hidden contest, which may be released — and solved — at any point during the convention.
Some catered meals are also included (see below).
You decide to come and pay the registration fee. The way most people do that is to pre-register for the convention. For registration info, click here.
The bulk of the registration fee pays for the convention space at the hotel and for hotel catering fees for meals. This year, there are five catered meals included, from Friday dinner through Sunday breakfast.
The rest of it goes to providing you with the best puzzling experience the League can offer. Every event is included in your convention fee. The program includes three unique games on Thursday night, three more on Friday night, three more on Saturday including a massive wordplay contest, and a giant puzzle-solving extravaganza on Saturday night. There's a welcome dinner on Wednesday if you come early. Plus you get a convention photo, convention speakers, lots of cryptic crosswords, all the after-hours activities, puzzle tours of neighboring attractions, snacks in the hospitality suite, a hidden contest, and a fancy nametag.
We might just have (and, at con, we call them nomtags). Being in the League is like joining a secret society of puzzle wonks, and we take our names seriously.
See, if you look on the home page, you'll notice that the Con hosts are B-Side and WXYZ. Those are noms. B-Side and WXYZ's real names are Ben and Wil, but you won't hear anyone use those names, except maybe if you're having some formal interaction with them on con business. That's because each of the NPL members has a nom de puzzle, usually just referred to as a nom. You'll be playing on teams with people whose puzzles you've solved for your entire lives. But when you're sitting with WILLz (that's Will Shortz) and Manx (that's Mike Shenk), those are just your teammates, y'know? Everyone's brain is considered equal at an NPL con. If you don't have a nom yet, don't worry — you won't find a shortage of congoers who want to help you pick one.
Much of the cost of the con covers common goods: The rooms where events are held, the hospitality suite, nomtags (see above), etc. In addition, we're a very small organization without much infrastructure, which means Eight Ninety (our awesome treasurer) and the Con hosts deal with each con registration personally (if you have any questions not answered here, feel free to reach out to ). Therefore, there really aren't any discounts, with two exceptions:
Everyone else pays full price.
There is a range of foods available at each meal, and we always attempt to satisfy vegetarians and vegans. If you have specific dietary needs, including if you're a vegetarian or vegan, please fill out your member profile to let us know of any allergies and/or foods you cannot eat, for any reason. The information you provide us is kept confidential and only provided to the con host and the hotel catering staff. If a dietary need or restriction that you have is not available in the form, please contact the webmaster.
If your dietary needs are very strict or unusual, we recommend you also contact the Con hosts (spamcon@puzzlers.org) to make sure that hotel catering can accommodate your needs.
If you are not a member of the NPL, or you are registering somebody who is not a member of the NPL, please contact the treasurer who can set up a non-member login which has its own profile data.
Please contact the Con hosts (spamcon@puzzlers.org) and/or the hotel staff.
There are no official activities planned for non-puzzlers, but some unofficial activities may be appropriate for them, and Minneapolis/St. Paul is an amazing city with lots to do. The Con Info provided by the Con hosts will provide some suggestions which will be useful both for NPL members arriving early and non-puzzlers looking to fill time while waiting for the puzzles to end. There are usually a fair number of people who bring children or spouses. Check the Attendance Notes page for information (and make sure to add your own information for others). The Con hosts may be able to help you connect with others who may want to do non-puzzling things together.
If you're not convinced yet and you're local, just come by. If we have room, we'll usually accept walk-ins all the way through the convention. If you'd like to see what we're up to, poke your head in — we have a drop-in policy. The best time to drop in is Thursday night, which starts with a mixer at 8:00 PM; if you can't make Thursday night, Friday night is almost as good. For details on this year's drop-in policy, check the convention's home page. (Just be aware that if your head looks like it's going to stay for the convention, we will ask it for money.)
No, but we recommend it. If you have friends in the area, or you live nearby, feel free to commute to the convention. Just make sure to let your friends know you might be stumbling in late after crazy nights of puzzling.
We may be able to accommodate some late registrants. Please send email to B-Side and WXYZ.
We sure hope so. But if not, send any more you have to B-Side and WXYZ.
And we'll see you at SPAMcon!
