What we agree on

Use of this site is covered by a short set of rules, written to be read rather than skipped.

The catalogue is informational. Prices, availability and delivery estimates shown here are a snapshot taken when the page was built, and the figure at checkout in the partner store listing is the one that binds anybody. If the two disagree, the listing is right and this page is stale.

Product photography, descriptions, guides and the artwork on this site belong to us. Quote a sentence with a link back and we will be pleased; republish a product page wholesale and we will ask you to take it down.

Some of the sets in this catalogue carry licensed characters and marks. Those names and likenesses belong to their owners, who license them to us for the products shown here and for nothing else.

We describe what our hardware does as accurately as we can, but we cannot promise any particular result from using it — nobody can guarantee a solve time, a chess rating or a stronger core. Treat the guides as informed advice, not instructions.
