Kenji's current recommendation
Keep the whole stack in Sixth
Use Sixth Edition base, the desired Sixth Edition expansion, and—only for five or six players—the matching Sixth Edition 5–6 Player Extension for each layer.
- Base extension expands the base components
- Expansion extension expands that expansion
- A base extension does not expand Seafarers or Cities & Knights by itself

Ready when
Base game, player extension, expansion, and expansion extension all match edition, language, player count, art, and current paired-player rules.What this tool assumes
An expansion and its 5–6 player extension are different boxes. Sixth Edition components should remain inside a matched Sixth Edition product family.Kenji's table briefing
The tool has a point of view. The rules still get the final word.
“Match the coastlines before you invite two more settlers.”

The useful part belongs beside the board.
Sixth Edition
Keep the whole stack in Sixth
Use Sixth Edition base, the desired Sixth Edition expansion, and—only for five or six players—the matching Sixth Edition 5–6 Player Extension for each layer.
- Base extension expands the base components
- Expansion extension expands that expansion
- A base extension does not expand Seafarers or Cities & Knights by itself
Fifth Edition
A complete fifth-edition shelf still plays
There is no need to replace a functioning matched set. Add fifth-edition expansions and extensions only when the exact edition is clear.
- Artwork, frames, rules presentation and components can differ
- Do not assume marketplace listings show the shipped edition
- Inspect the box front and edition language
First expansion
Seafarers changes the map; Cities changes the decisions
Seafarers is the friendlier first expansion for groups that love exploration. Cities & Knights is the deeper first expansion for groups that want defensive pressure and development.
- Traders & Barbarians is a scenario toolbox
- Explorers & Pirates is a larger structural departure
- Teach one major expansion at a time

Fast rulings before the table
Common questions, answered without the forum fog.
Is a 5–6 Player Extension the same as an expansion?
No. An extension raises player count. An expansion changes play. A five- or six-player expansion table normally needs both matching extensions.
Can fifth- and sixth-edition CATAN products be mixed?
Keep a matched edition family. Component art, frames, wording, and current paired-player rules differ enough that mixed stacks create avoidable friction.
Is the CATAN Compatibility Decoder an official publisher tool?
No. It is an independent Puzzlewick planning aid checked against CATAN: current rules archive and product FAQs. When the tool and current publisher material differ, the publisher rulebook, FAQ, errata, or event packet controls.
