Reasoning and memory challenges

These challenges ask you to work something out or hold it in mind: a hidden rule in a grid of shapes, a shape turned in your head, or a sequence of lit cells.

Start with Entry to learn the format. Regular adds more items of the same kind, and Hard combines rules or adds length. None of them gives an IQ number or a memory diagnosis.
