For this achievement you
ALWAYS have to make sure to do a
SAVEGAME before every minigame that you need to reload after the specific minigames have been finished.
Here is a list of all 6 minigames with the corresponding achievement. For details and tips on any of the minigames, check out my guides on them:
1st game is at "The Collection" in Chapter 1:
2nd game is at "The Chapel" in Chapter 1:
3rd game is at "The Police Station" in Chapter 2:
4th game is at "The Prairie" in Chapter 2:
5th game is at "The Bridge" in Chapter 2:
6th game is at "Edna's Cell" in Chapter 3:
Definetely make sure to have a proper
SAVEGAME before every minigame if you don't want to play it twice like me. I did, but still the achievement didn't unlocked on the first run.
