So you want to become a member? That’s awesome! Students of Leiden University or the Higher Professional Education in Leiden are always welcome to join Het Duivelsei! You can join throughout the year, but we recommend you to join during the orientation week, because you can go to the introduction weekend!
Het Duivelsei is open one or two evenings every week, usually on either Tuesday, Thursday or Friday, and one Saturday per month, which makes us the perfect association to combine with your other activities in the week. The dues is just €35 for a whole year, but for a number of activities, such as laser gaming or the introduction weekend, we’ll charge extra. Do you become a member after January 31st, then you will only have to pay €17,50. Besides paying your dues there’re no further requirements/liabilities to become a member!

Are you interested in becoming a member? Send an e-mail to bestuur@duivelsei or drop by and ask for a board member.


Your membership is valid from the moment you’ve signed your membership form. From that moment you are, as a member, always welcome at our activities and you’ll get our association magazine (in Dutch). In our cabinets you’ll find hundreds of games to play and you can always borrow any of these games with the permission of the board.
The dues is €35 for the whole academic year, from September 1st till August 31st. If you’ve given permission then we’ll collect this sum through an automatic collection, otherwise you’ll have to transfer the sum yourself. If you don’t pay on time, we’ll have to give you a €5 fine.

Changes in address, phone number or e-mail and terminating membership

We appreciate it if you notify us when your address, phone number or e-mail address changes by sending an e-mail to abactis@duivelsei.
Your membership of Het Duivelsei will continue until you terminate it by sending an e-mail to abactis@duivelsei, titled ‘Terminating membership’ or by contacting us by sending us a letter to our posting address (see the page ‘Contact). Doing this by replying to a different e-mail send by us doesn’t count as a termination. If you don’t do this before August 1st , then we’ll presume that you want to stay a member for another academic year.
If you don’t want to be a member anymore, but you want to stay connected to the association? Become a Duivelsei alumnus.

Becoming an alumnus

Haven’t got any time for Het Duivelsei or just feel too old to play games with a bunch of nerds in a cellar? Then maybe becoming an alumnus of Het Duivelsei is something for you! For €20 a year you can still come by 6 times each year and you still get the association magazine in your mailbox! Furthermore, you’ll be kept up to date with the goings on of the association with two alumni-updates each year!
For questions and to sign up you can send an e-mail to abactis@duivelsei.
