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.
Choose the classic 19-hex map for 3 and 4 players, or the 30-hex expansion for 5 and 6 players.
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.
Copy the layout onto the table, or leave the phone in the middle of the table and read it from the screen.
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.
| Number | Pips | Chance | Bar |
|---|---|---|---|
| 2 | 1 | 2.8% | |
| 3 | 2 | 5.6% | |
| 4 | 3 | 8.3% | |
| 5 | 4 | 11.1% | |
| 6 | 5 | 13.9% | |
| 8 | 5 | 13.9% | |
| 9 | 4 | 11.1% | |
| 10 | 3 | 8.3% | |
| 11 | 2 | 5.6% | |
| 12 | 1 | 2.8% |
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.
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.
The mirror of the first rule. It stops the two weakest numbers from wasting a whole corner.
No corner ends up collecting the same number twice on one roll.
It breaks up the large blocks of one resource, which is the usual complaint about a random board.
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.
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.
Yes. The expansion uses 30 hexes, 28 number tokens and 2 deserts, and every rule applies to the larger map as well.
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.
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.
No. The generator runs in the browser on a phone, a tablet or a laptop. It needs no account, no install and no payment.
