This achievement is easy, but can be very frustrating. Could take many games to get. To get it you have to use cheese to trap the player and win the game. I can't remember what spot exactly you have to land on, but one of the spots lets you roll the dice for the other player by using cheese. You have to land on that spot, with cheese, and then you have to roll the right amont to land the other player under the trap, trap falls and you win, achievement unlocked.
I got this achievement in Family Game Night 3, have not got it in the Fun Pack yet.
