*** Spoiler - click to reveal ***There are four mini-game puzzles:
1) In chapter 2 where you match the instruments
2) In chapter 2 solving the prayer wheel story
3) In chapter 3 getting the party across the fallen bridge
4) In chapter 3 feeding candies to the Lumi's
If you hit the 'skip' button in the corner for all four puzzles, the achievement will unlock. (You must do this in the same savegame.)
Note that mini-games #2 and #3 also have achievements related to solving them so you'll need another playthrough to get those.
