What Happens When You Roll a 7 in Catan? Hand Limits and Robber Rules Explained
By Autumn Wohlwend, published 2026-09-29. Rolled a 7 in Catan? Everyone over 7 cards discards half first, then the robber moves, then you steal one card. Here is the exact order and the edge cases groups argue about.
Quick Answer: When a 7 is rolled, three things happen in order. First, every player holding 8 or more resource cards must discard half, rounded down. Then the player who rolled moves the robber to a different hex. Then that player steals one random card from any opponent with a settlement or city touching the new hex.
Rolling a 7 in Catan causes more table arguments than almost anything else in the game. Not because the rule is complicated, but because most groups learned it slightly wrong the first time and have been playing it that way ever since.
Here is what actually happens, and in what order.
Step 1: Everyone Discards First
This is the part people get wrong most often.
The limit is 7. If you have exactly 7 cards when a 7 is rolled, you are safe. If you have 8 or more, you have to discard half of your hand, rounded down. You get to choose which cards you give back.
This applies to every player at the table, including the person who rolled. It is not just the player with the most cards. It is not just your opponents. Everyone over 7 discards, all at the same time, before the robber moves at all.
If you have 9 cards, you discard 4 and keep 5. If you have 12, you discard 6.
Step 2: Move the Robber
After everyone finishes discarding, the player who rolled moves the robber to any other hex on the board.
A few things people argue about here:
Can you move the robber back to the desert? Yes. The official rules say you can move it to any other terrain hex, including the desert. Some groups treat the desert as off-limits, but that is a house rule.
Do you have to move it? Yes. The robber must move to a different hex. You cannot leave it where it is, even if you would rather not block anyone.
Can you put it back where it just was last turn? Yes, as long as it moves somewhere different this turn.
Step 3: Steal a Card
Once the robber is placed, you steal one random resource card from any player who has a settlement or city touching that hex. You pick blindly; you cannot look through their hand first.
If no one has a settlement or city on that hex, no one loses a card. That is a legal move, even if it feels like a waste.
Common Edge Cases
What if I play a Knight card instead of rolling a 7? Knight cards let you move the robber and steal, but they do not trigger the discard rule. Only a rolled 7 causes everyone to discard.
What if I roll a 7 but I also have 8 or more cards? You still discard first, then move the robber. Rolling the 7 does not exempt you from your own hand limit.
What if nobody is adjacent to where I move the robber? Nobody loses a card. You still have to move the robber, but stealing only happens if an opponent has a settlement or city touching the new hex.
