Welcome to our shop. First, click on the desired number of groups. Then "Add to cart" and press "Buy".

 

 

There can be no more than 10 people in a group.

The less you choose to be in a group, the better you ensure that all participate actively.

There are only two routes in the mystery. If you are more than two groups, group 3 and 4 must start fifteen minutes later than the others.
