Alphabetty level 739: six words is way too much.
No matter what booster is used, 6 words is an impossible achievement.
Most of the first 8 moves is spent chasing -2 bombs, and even trying to get useful words while cleaning up the bombs is further frustrated by the lack of 1 or 2 letters across the board, which can only be obtained by creating a crown and making a word out of it, so that the missing letter appears - for a minimum total of 3 moves (1: create 4-letter 2:use crown 3:use missing letter in word).
And there's quite a few blocker traps to add in the mix...I've gotten somewhat close to 5 words, but never even reached that - it's fairly obvious that the game needs one or more of:
1. add more moves (no less than 4, but this may still be too low)
2. be a bit less stingy with missing letters so the player isn't wasting 3+ moves per letter
3. remove a few bombs across the board so the player can focus on actually finding relevant words
