There are two kinds of people in the world: the ones who carefully build the Mouse Trap contraption like it’s a tiny engineering project… and the ones who immediately flick the lever to see if the cage drops. Both are valid.
Mouse Trap is one of those games everyone “remembers,” right up until the first argument breaks out over when you’re allowed to launch the trap, whether landing on the cheese space means you’re doomed, and why the marble is suddenly on the floor. This guide clears up the rules fast so you can get to the important part: collecting cheese and dropping your friends into the trap at the worst possible moment.
You win by being the first player to collect 6 cheese wedges (a complete cheese wheel).
What You Need to Play
- Mouse Trap gameboard
- 2–4 mouse pawns
- Mouse Trap contraption parts (plus rubber band)
- Cardboard cheese wedges
- 1 marble
- 1 die
Affiliate-friendly add-ons (optional, but genuinely useful):
- A small parts organizer or zip pouch for trap pieces
- A playmat or felt table cover (the marble behaves better when your table isn’t a ski slope)

- Operation (steady hands, loud opinions)
- Sorry! (same level of friendship testing)
Setup
- Lay the gameboard on a flat, stable surface.
- Assemble the entire Mouse Trap contraption on the board (the classic chain reaction).
- Give each player 1 cheese wedge to start.
- Put 2 cheese wedges on the Start space as a bonus. The first player to make it all the way around the board collects them.
- Put the remaining cheese wedges in a pile near the board (the “cheese stash”).
- Each player chooses a mouse and places it on Start.
How to Play
- Roll to see who goes first. Play continues to the left.
- On your turn, roll the die and move your mouse clockwise that many spaces.
- Do what the space says based on its color/type (details below).
- If you land on a space another player is on, move ahead to the next available space. (No stacking.)
- If the trap gets launched on your turn, reset it before your turn ends (so the next player isn’t stuck doing your chores).
Space rules (the part most people “kind of remember”)
- Yellow (Add-a-Cheese): Take 1 cheese wedge from the stash.
- Green (Steal-a-Cheese): Steal 1 cheese wedge from any player who has one.
- Red (Lose-a-Cheese): Return 1 of your cheese wedges to the stash. If you have none, you’re still in the game.
- Purple: Nothing happens. (A reflective moment.)
- Mousehole Tunnel: If you land here, you may travel to the matching-color tunnel exit.
Launch-the-Trap (blue) and the Cheesy Danger Zone
This is where many players get confused: being on the Cheesy Danger Zone does not automatically launch the trap.
- Blue (Launch-the-Trap): Choose one player and move their mouse to the Cheesy Danger Zone, then launch the trap. If they get caught, you take 1 cheese wedge from them.
- If a mouse is already in the Cheesy Danger Zone, you can still send another one there, and you collect 1 cheese wedge from each mouse that gets caught.
- Cheesy Danger Zone (the cheese space): If you land here by exact count, you stop, but do not launch the trap. You’re just waiting there bravely.
- If you get caught, you are still in the game. After resetting the trap, your mouse stays in the Cheesy Danger Zone and starts from there next turn.
How the Game Ends
The game ends immediately when someone has collected six cheese wedges (a full cheese wheel).
Also: going all the way around the board does not end the game. You keep looping until someone hits six.
How to Win
Be the first player to collect 6 cheese wedges.
Strategy Tips
- Target the leader with the trap. If someone has 4–5 wedges, sending them to the Cheesy Danger Zone is basically your job now.
- Green spaces are often stronger than yellow. Stealing is cheese gain plus opponent loss, which is the kind of math Mouse Trap quietly encourages.
- Use tunnels to dodge bad spots or line up blue spaces. The tunnel is one of the few “choices” you get, so take it seriously.
- Reset cleanly. A sloppy reset makes the trap fail later, and the table will blame you even if physics is clearly at fault.
Common Mistakes
- Launching the trap when someone lands on the Cheesy Danger Zone. You only launch when a player triggers the blue Launch-the-Trap action.
- Trying to steal from a player with zero cheese. You can’t steal cheese from someone who has none.
- Stacking mice on one space. If a space is occupied, move to the next open space.
- Forgetting the Start bonus. The first player all the way around collects the two wedges on Start, and yes, it matters.
Quick Reference Summary
- Win: First to 6 cheese wedges
- On your turn: Roll, move clockwise, resolve space
- Yellow: Gain 1 cheese
- Green: Steal 1 cheese
- Red: Lose 1 cheese (still play if you have 0)
- Blue: Send someone to Cheesy Danger Zone + launch trap
- Cheesy Danger Zone: Stop there, but don’t launch trap just for landing
- Occupied space: Move to next available space
- Tunnel: Optional jump to matching-color exit
