Dates of first publication—chronological
This chronology shows, by year, the order in which we introduced our products and their later editions. All these gamepuzzles are still made and sold on this website. We don't usually discontinue a product, once we commit ourselves to its release, unlike the mass-market game industry. A few items are on indeterminate hiatus, and we sometimes bring them back in new versions. Many new designs are in the works and will be introduced when their time comes.

This list is not provided with links. Should you want to see a specific item, please find it in the regular alphabetical listing or the alphabetical by release date list.

Special limited editions we designed by commission for a one-time use or private customer are also listed here. You can see some of them among the Special Editions categories in the Search Index. Others may become products eventually.

A growing number of custom designs by Kate were made or printed as collectors' gifts only. You can find them in the IPP and Gathering for Gardner write-ups.
