Letter Quest: Grimm's Journey Remastered

Both of these achievements are unlocked by spelling the respective words in either game mode. Since there is a random element involved in getting the required letters, there is some luck involved. It's best to wait until you've got a few of the required letters on your board, and then purposely save them and use other letters until you've got all the ones you need.

If you don't unlock this during Story mode, it's much easier to attempt this in Endless mode since you don't have to worry about defeating all of the monsters and the stage ending.
