Looking for some cool game to participate in to win a prize? And not just any prize, no, you can win 2 gala tickets! The only thing you have to do is participate in this puzzle hunt. It's as simple as that!

It works as follows: every week (the Christmas holiday excluded) we will make a puzzle available on Thursday. From then, you will have a week, until Wednesday 23:59, to send an email to lustrumpuzzeltocht@a-eskwadraat.nl with your name and the solution to the puzzle. Participation is individual, so don't share your answers, not even with your friends! 😉 The puzzle hunt will take place until Wednesday, February 11, 2026, 23:59.

The two gala tickets will be rewarded to the person that solved the most puzzles. In the case that more people solved the same number of puzzles succesfully, the person with the fastest average time will win the tickets!⏰️

So keep checking the site and our insta (@lustrum_aes) weekly for the puzzles! Have fun solving the puzzles!🧩

This is the first puzzle of many, so we will start with a classic one: a crosswordpuzzle! The puzzle can be found under the photos of this activity. If you were present at the theme announcement of our lustrum, the puzzle will most likely be a breeze. If you aren't so lucky to know all answers right away, you may be helped by checking our instagram account or by watching this video. Good luck solving the puzzle! We are looking forward to all your answers!
