This event is an online puzzle hunt that has been created for the the conference Lattice Paths, Combinatorics and Interactions. The puzzles may include references to the conference, to combinatorics or to math in general.
The puzzle hunt will be played during the week of 21st-26th June, 2021.
There are 6 puzzles in total, available in the Puzzles page: 4 main, independent puzzles, a final puzzle (“metapuzzle” which will be available to teams having solved all 4 first puzzles), and a Bonus puzzle.
This is a private event, the Puzzles page is password-protected and accessible only to the participants of the conference. Please ask me for permission before sharing a puzzle with someone not related to the conference.

The puzzles in this game are in puzzle-hunt style: they come with no, or minimal, instructions. The first step is to figure out what to do, and use the information or data to extract some meaning. They often require one intuitive leap in thinking (or aha-moment) to solve.
You may use the internet to search for information (some of the puzzles are impossible to solve without looking things up).
The goal is to find the answer to each puzzle. The answer is usually an English word or phrase.
Each answer must be entered in a specific field (in a Google Form) just below the corresponding puzzle. You should write each answer in lowercase. Submitting your answer in the form also enters your team into the “Hall of Fame” (leaderboard) for each puzzle.
To solve the metapuzzle you will need to use the 4 first puzzle answers.
Each puzzle is entirely contained in a pdf file. You don’t need to do technical things to the pdf (nothing hidden in the metadata or concealed by steganography!). There are no clues on this website outside the pdf files.
It is not necessary to print the puzzles. But it may be useful to have a way to annotate or draw on the pdf electronically.

(what to do if you are stuck)

If you are confident in your answer, but the form does not accept it, check that you typed it correctly (lowercase, without spaces), and that you indeed have the complete answer (in some puzzles there may be an indication of the word length(s) of the answer).
Re-read the title and the introductory text carefully. They may contain clues.
Consider what information you haven’t used yet.
Thoroughly check the work that you’ve already done.
Google things you don’t know. Google things you know.
Take a break, look at another puzzle.
Look up a specific hint in the Hints page, or ask for a personalized hint verbally or by email.

(when solving as a team during a videoconference)

One team member can share their screen with the puzzle on it, so that everyone can annotate the screen.
Use the virtual whiteboard in the videoconference software.
Use a shared folder (e.g. in Google Drive) and share notes in documents or worksheets among your team.
