Be early! Please arrive at least 15 minutes early. We like to go over the rules, give you some tips and tricks, and let you try some practice puzzles to get you ready for the real thing. If you're late however, we unfortunately cannot wait for you as we usually have other groups that are booked after your group. Your room timer starts at the time you booked, with or without you present. We will try our best to accomodate your group if you are late but we cannot offer refunds.
