I have played more than 300 games of Catan, and the pattern never changes: the player who understands Catan settlement placement probability wins about twice as often as the player who picks spots that “look good.” Learning how to use probability to choose the strongest settlement spots in Catan is the single fastest upgrade you can make to your game. It takes about ten minutes to learn the math, and it pays off on the very first turn.
Here is the short version: two dice roll each turn, every number has a fixed chance of appearing, and your job during setup is to claim the intersections with the highest total production. The famous dot counts on the number tokens are not decoration. They are a pre-calculated probability score sitting right on the board.
In this guide, I will walk through the exact numbers, the pip count method I use to score any intersection in seconds, and the trade-offs between probability, resource diversity, ports, and the robber. If you are also teaching strategy games to kids, this same pip-counting exercise is a great way to sneak real math into game night.

Why Your Opening Placement Decides the Game?
Your two starting settlements decide roughly half of your final result before anyone takes a turn. Every card you will ever earn flows through the six number tokens touching those first two intersections. A weak start means you spend the midgame trading at brutal rates just to stay relevant.
The most common complaint I see on Catan forums is the same every time: “I got resource-locked by turn five.” That is not bad luck. That is a placement that bundled every settlement onto one or two numbers, or onto resources the board barely produces.
How Catan Settlement Placement Probability Works: The 2d6 Basics
Catan rolls two six-sided dice, so there are exactly 36 possible outcomes, and every number from 2 to 12 has a fixed, known probability. A number pays you one card every single time it rolls, which means its share of those 36 outcomes is its share of your income. That is the entire foundation of Catan settlement placement probability.
Seven rolls 6 of the 36 ways (16.67%), six and eight roll 5 ways each (13.89%), and the count drops as you move away from seven. The pip dots printed under each number token simply show how many of the 36 combinations produce that number.
| Number | Combinations out of 36 | Probability | Pips (dots) | Cards per 72 rolls |
|---|---|---|---|---|
| 2 | 1 | 2.78% | 1 | 2 |
| 3 | 2 | 5.56% | 2 | 4 |
| 4 | 3 | 8.33% | 3 | 6 |
| 5 | 4 | 11.11% | 4 | 8 |
| 6 | 5 | 13.89% | 5 | 10 |
| 7 | 6 | 16.67% | Robber | Robber moves |
| 8 | 5 | 13.89% | 5 | 10 |
| 9 | 4 | 11.11% | 4 | 8 |
| 10 | 3 | 8.33% | 3 | 6 |
| 11 | 2 | 5.56% | 2 | 4 |
| 12 | 1 | 2.78% | 1 | 2 |
Read the last column and the whole strategy clicks. A 6 produces about ten cards every 72 rolls; a 2 produces two. Touching a 6 instead of a 2 means five times the income from that hex, forever, with zero extra effort.
A typical game runs 60 to 90 rolls. When players say a number “never rolled all night,” they are usually describing a 2, 3, 11, or 12 doing exactly what the math predicts.
Tip: You do not need to memorize percentages. Just remember the pip dots: 5 dots is elite, 4 is strong, 3 is average, 2 is thin, 1 is nearly dead.
The Best Numbers to Settle On in Catan
6 and 8 are the best numbers in Catan, followed by 5 and 9, then 4 and 10, with 3, 11, 2, and 12 as last resorts. That ranking is pure math, not opinion: it is the exact order of how many dice combinations reach each total.
Tier 1: 6 and 8 (5 pips, 13.89% each)
The red numbers pay out five cards per 36 rolls, almost twice as often as the outer numbers. An intersection touching both a 6 and an 8 produces on ten of 36 combinations, which is more than a quarter of all rolls. If you can pair a 6 or 8 with a 5 or 9, you have found a premium spot.
Tier 2: 5 and 9 (4 pips, 11.11% each)
These are the quiet workhorses. Community consensus is that players consistently undervalue 5 and 9 even though they produce 80% as often as the red numbers. A 6-5 or 8-9 intersection is nearly as strong as a double-red and usually faces less competition.
Tier 3: 4 and 10 (3 pips, 8.33% each)
Fine as a third number on an intersection, risky as your main source of income. I will happily take a 4 when it sits next to a 6 and adds a resource I am missing.
Tier 4: 3, 11, 2, and 12 (2 pips or fewer)
Only take these for a specific reason: a scarce resource, a key port, or a blocking move. A 2 or 12 pays roughly one card every two laps of the table, so plan to expand off these spots quickly.
Good news for placement: the official number token layout never places red numbers on adjacent hexes, so no legal board offers a 6-6-8 monster intersection. The practical ceiling is something like 6-8-5, and those spots go first.
The Pip Count Method: Score Any Spot in Seconds
The pip count method turns settlement evaluation into simple addition: add the dots from the three hexes touching an intersection, and compare that total to your benchmarks. You can score the entire board during setup in under a minute.
Here is the exact process I use, in order:
1. Count the dots on each of the three number tokens touching the intersection.
2. Add them together for the spot’s raw pip score.
3. Note which resources those pips produce, not just how many.
4. Repeat for every intersection you could legally claim.
5. Rank the spots, then break ties using resource mix and expansion paths.
| Intersection pip total | Quality | Cards per 72 rolls |
|---|---|---|
| 13+ pips | Exceptional, take immediately | 26+ |
| 11-12 pips | Strong opening settlement | 22-24 |
| 9-10 pips | Playable, check the resources | 18-20 |
| 7-8 pips | Weak, need a plan to expand | 14-16 |
| 6 or fewer | Avoid unless blocking or port play | 12 or fewer |
Here is a worked example from a game I tracked last month. Spot A touched a 6 on brick, a 9 on wheat, and a 10 on wood: 5 + 4 + 3 = 12 pips. Spot B touched a 2 on ore, an 11 on sheep, and a 3 on wheat: 1 + 2 + 2 = 5 pips.
Across 72 rolls, Spot A pays about 24 cards and Spot B about 10. Same board, same dice, same number of turns. That 14-card gap is the entire game, and it was decided before the first roll.
Do the same math per resource, not just per spot. If your two starting settlements combine for 18 or more pips on wheat and ore, a city strategy is live; under 10 combined pips on wood and brick means you will buy every road from other players.
Resource Diversity vs. Raw Probability
When two spots are within two or three pips of each other, the more diverse spot usually wins. Probability fills your hand; diversity decides what you can actually build with it. The real tension in Catan is exactly this trade-off, and forums argue about it because both sides keep winning games with opposite styles.
Scarcity matters as much as frequency. A standard 3-4 player board has four hexes each of wood, sheep, and wheat, but only three brick and three ore. A 4 on your only brick often outproduces a 5 on your fourth sheep, because scarce resources trade at a premium and nobody can undercut you.
Match the resource mix to the phase of the game:
Wood and brick: the expansion engine. You need them for roads and settlements in the first ten turns, and a start without them quietly locks you in place.
Wheat: needed for everything. Settlements, cities, and dev cards all cost wheat, so I treat wheat pips as slightly more valuable than their face value.
Ore and wheat: the city engine. Weak early, dominant from the midgame onward.
My rule of thumb after hundreds of games: take a 10-pip spot covering four or five resources over a 12-pip spot covering two. The exception is when the 12-pip spot lines up with a clear win condition, which we will cover below.
Ports and Trading: When Flexibility Beats Pips
A port is worth taking when its rate improvement multiplies a resource you already produce heavily, not as a substitute for production. The bank charges 4:1, a generic 3:1 port cuts that to three cards, and a 2:1 specialty port cuts it to two.
The math is straightforward. If you hold the 2:1 wheat port and your settlements carry ten wheat pips, every four wheat you ship become any two cards you want. That converts your surplus into exactly the missing resource at a rate no opponent will offer you.
The 3:1 port suits diverse boards where you rarely hold four of any one thing; the 2:1 port suits a board stacked in a single resource.
Warning: never take a port on a low-pip intersection. A great rate on cards you never draw is worth nothing. Port first, pips second is the fastest way to watch everyone else pass you on the score track.
The Robber: Why the Most Common Roll Changes Everything
The robber is the hidden villain of placement math, because 7 is the single most common roll in the game at 16.67%, or one roll in six. Every seven blocks your most productive hex until the next seven appears, and it arrives more often than your best number does.
This is why spreading your numbers matters more than it first appears. A player with settlements on 6, 6, and 8 has huge raw pips but only two production numbers, so one robber placement shuts off half their income. A player on 5, 6, 8, 9, and 4 keeps earning through almost every robber visit.
Two related rules shape this. First, anyone holding more than seven cards when a 7 rolls discards half their hand, so clustered high producers can actually feed your losses. Second, the robber placement is often political: the player who grabs the double-red intersection should expect to host the robber all game.
Use the robber on offense too. When you place settlements, note which opponent depends on a single 6 or 8. Sending the robber there on the first seven of the game is often worth more than a card.
Six Beginner Mistakes That Sink Good Boards
Most placement disasters come from six repeated errors, and each one has a simple fix. I made every one of these for my first fifty games.
1. Taking pips without checking resources. A 12-pip spot covering two resources feels great until you cannot build anything. Fix: require at least three resources across your first settlement.
2. Cloning your numbers. Two settlements that all touch 6 and 8 score huge until the robber arrives. Fix: overlap at most one number between your starting spots.
3. Ignoring brick. With only three brick hexes on the board, the player who skips brick buys every road at 4:1. Fix: claim brick pips in your first two placements or plan a port.
4. Choosing a port before production. The 2:1 port on a 6-pip intersection is decorative. Fix: ports only on 9-pip-plus intersections or later placements.
5. Forgetting the second settlement’s job. Your first spot sets your engine; your second should patch its holes and grab a scarce resource. Fix: after placement one, list what you lack, then fill it.
6. Blocking no one. Setup is also defense. If your spot can sit one intersection from an opponent’s expansion while keeping 10+ pips, take that version.
Example: A Strong Start vs. a Weak Start
Here is a real board shape from a recent session, with both placements compared over the same 20 rolls. Same table, same dice sequence, opposite outcomes.
Player A: Settlement 1 on 6-brick, 9-wheat, 10-wood (12 pips). Settlement 2 on 8-ore, 5-wheat, 4-sheep (12 pips). Combined 24 pips across five different numbers and all five resources.
Player B: Settlement 1 on 3-sheep, 11-wood, 2-ore (4 pips). Settlement 2 on 4-brick, 10-sheep, 3-wheat (8 pips). Combined 12 pips across six numbers but heavy on the outer ring.
Over 20 rolls, Player A drew about 13 cards and Player B about 7. Player A built a third settlement on turn nine; Player B was still hand-trading for brick on turn twelve. Player A won 10-6, and the game was effectively decided at setup.
Match Your Placement to Your Win Condition
Strong placement is not one template; it is picking a win condition and buying its ingredients while everyone else fights over red numbers. Three archetypes cover almost every game.
The Longest Road (wood and brick rush)
You need heavy wood and brick pips, ideally 12 or more combined, plus expansion room along the board’s edge. Your settlements are feeders for a road-building engine, so raw spacing matters more than diversity.
The City Rush (ore and wheat)
You want 16 or more combined pips on ore and wheat across your first two settlements. This start is slow for the first six or seven turns, then snowballs as cities double your best hexes without needing new numbers.
The Dev Card Engine (ore, wheat, sheep)
Take steady ore, wheat, and sheep pips and buy cards instead of racing for space. It dodges the road-building arms race entirely, and largest army plus victory points hidden in hand ends games quietly.
The board picks your archetype far more than your preference does. Count the pips by resource pair during setup: whichever of wood-brick or ore-wheat totals higher is the strategy the board is dealing you this game.
The 60-Second Settlement Checklist
Run this list in order every time a settlement or city placement comes up, in setup or midgame. It takes about a minute and prevents nearly every mistake above.
1. Add the three pips: is the spot 9 or better?
2. Which resources do those pips pay, and am I duplicating what I already own?
3. Does this patch my scarcest resource, especially brick or ore?
4. Do the numbers overlap my other spots, or am I spreading for robber insurance?
5. Is there a port in reach, and does its rate match my surplus?
6. Where does this let me expand next, and is that path contested?
7. What does this placement deny my closest opponent?
8. Does this match my win condition’s resource pair?
If a spot answers yes to five or more, take it. If two spots tie, take the one with the better expansion path, because pips now can be replaced while position cannot.
Frequently Asked Questions
What are the best numbers to put your initial settlements on in Catan?
6 and 8 are the best numbers, each producing on 5 of 36 dice combinations (13.89%), followed by 5 and 9 (11.11% each), then 4 and 10 (8.33%). Aim for starting intersections that combine numbers from the top two tiers, such as a 6-5-9 or 8-9-4 spot, and treat 2, 3, 11, and 12 as filler numbers you accept only for scarce resources or ports.
How often does a 7 get rolled in Catan?
A 7 is rolled on 6 of the 36 possible two-dice combinations, which is 16.67% of all rolls, or about one roll in six. That makes 7 the most common result in the game, which is why the robber moves so often, why hands over seven cards discard half, and why spreading your production across several numbers beats stacking everything on one red number.
How do you calculate probability in Catan?
Count how many of the 36 possible two-dice combinations sum to your number. A 6 can be made 5 ways, so its probability is 5 divided by 36, or 13.89%. The dot count printed under each number token is that combination count, so you can skip the division entirely: just add the dots on the tokens touching an intersection to get its relative production strength.
Should I always go for the highest dots when placing settlements?
No. When two spots are within two or three pips of each other, the spot with better resource diversity, scarce resources like brick or ore, or less number overlap usually wins. Raw pips measure how many cards you draw, not what you can build with them, so a 10-pip spot covering four resources typically beats a 12-pip spot covering two, especially against the robber.
Are ports worth settling on in Catan?
Ports are worth it when the settlement also has strong production, typically 9 or more pips, and the port rate matches a resource you produce in surplus. A 2:1 wheat port next to ten wheat pips converts surplus into any card at a rate no opponent will trade. A port on a low-pip intersection is close to worthless because you need cards before rates matter.
What makes a Catan board balanced?
A balanced board spreads the high numbers (6, 8, 5, 9) across different resource types so no single resource corners all the production, and keeps the three brick and three ore hexes reasonably strong. When the top pips all sit on sheep and wheat while brick carries only 2s and 3s, the board is unbalanced, and you should overpay in pips to claim whatever scarce resource is starved.
Put the Math to Work on Your Next Board
You now know how to use probability to choose the strongest settlement spots in Catan: add the pips, demand 9 or better per spot, spread your numbers against the robber, and fill resource gaps with your second placement. Those habits alone put you ahead of most tables, and they cost nothing but a minute of counting during setup.
Start small at your next game night: score three candidate intersections with the pip count method and pick the one that passes the checklist. If you are bringing newer players up to speed, this guide to teaching a strategy game that is slightly above someone’s age level uses Catan-style games as the perfect training ground.
The dice will always surprise you in any single game, and that is part of the fun. Over ten games, though, the player who respects Catan settlement placement probability wins the games the math says they should, and updated for October 2026, that player can be you.
