### More Guess My Word Puzzles

Solution to Guess My Word Puzzles

We can use the clues “JUNKS = 0” AND “STINK = 0” to eliminate those letters in the other words.

H U N K Y = 2

W H I S K = 2

C E N T S = 2

The letters that are left spell CHEWY.

H U N K Y = 2

W H I S K = 2

C E N T S = 2

This puzzle is harder. One thing we can do is to compare words that are similar but have different point values.

For example, if GRAIN = 3 and GRANT = 4, then replacing the letter I with a T adds a point to the word. (The two words share their other letters – GRAN.). Therefore, we know the mystery word must have a T (and must not have an I.)

Solution: GRUNT

A good place to start is to notice that PAYER has one more point than LAYER. Therefore there must be a P in the mystery word and must not be an L.

Notice also that by comparing BEAMS to SMART, we can see that R and T must be in the word and B and E must not.

Solution: PARTY
