Catan board generator

Shuffle a board for the classic map or the expansion, and set what the layout has to keep apart.

catan.gg draws a random Settlers of Catan board for the classic 19-hex map and for the 30-hex expansion for 5 and 6 players.

Tick the rules the layout has to obey, press shuffle, and copy the board onto the table. Every number token carries its pip count, and the slip on the table shows what the board pays per resource. It is free, it needs no account, and it runs in the browser.

How to set up a board

  1. Pick the set

    Choose the classic 19-hex map for 3 and 4 players, or the 30-hex expansion for 5 and 6 players.

  2. Set the rules

    Tick what the board must keep apart. The generator places the hexes and the tokens around your choice, and it never settles for a layout that breaks a rule.

  3. Build the board

    Copy the layout onto the table, or leave the phone in the middle of the table and read it from the screen.

What each number pays

Two dice give 36 combinations. The pips under a number count how many of those combinations produce it, so a 6 or an 8 pays five times more often than a 2 or a 12.

The four setup rules

Two rules are ticked when the page loads. The other two are house rules that many groups play with, so they are yours to turn on.

Keep 6 and 8 apart

The printed manual states it. The 6 and the 8 pay the most, so a pair of them on one corner decides the game early.

Keep 2 and 12 apart

The mirror of the first rule. It stops the two weakest numbers from wasting a whole corner.

Keep matching numbers apart

No corner ends up collecting the same number twice on one roll.

Keep matching resources apart

It breaks up the large blocks of one resource, which is the usual complaint about a random board.

Common questions

How does the generator place the numbers?

It fills the map one hex at a time, hardest position first, and steps back whenever a position runs out of pieces. That is why it can satisfy a rule such as keeping matching resources apart, which shuffling and re-checking almost never reaches.

Can 6 and 8 touch on a generated board?

Not while the rule is ticked, and it is ticked by default. That rule matches the printed manual. Untick it if you want a wilder map.

Does it support the 5–6 player expansion?

Yes. The expansion uses 30 hexes, 28 number tokens and 2 deserts, and every rule applies to the larger map as well.

What do the dots under each number mean?

The dots are pips. Each pip is one of the 36 combinations that two dice can roll, so a 6 or an 8 carries five pips and a 2 or a 12 carries one.

What is the balance score?

It compares the pip total of each resource against an even split. A board at 100 pays every resource equally. A board at 60 leans hard on one or two of them.

Do I need an account?

No. The generator runs in the browser on a phone, a tablet or a laptop. It needs no account, no install and no payment.
