Different kinds of problems
Its own collection page mentions tangram, sliding puzzles, metal puzzles and construction puzzles, among others. One type is about arranging, another about taking something apart or building it up. These differences offer a simple way to find your way around the collection.
What your eyes tell you
Hidden-picture puzzles and optical illusions are also part of the collection described. Here your first impression is actually an interesting starting point. See what changes when you look for longer or turn your attention to another part.
From display case to having a go
Besides the displays, space for trying puzzles yourself is described. When making the appointment, ask which items are available for this. Finding the solution need not be the only goal: recognising why an attempt gets stuck can be enjoyable too.
Before you go
Always make an appointment in advance. Ask about access to the different floors if stairs are a limitation for you.
