Thread Words, from Amazon Digital Services, is a word search game for Kindle.
Your goal is to find words in a 5 high grid of letters. Find words by selecting one letter from each column. On each level there are ten pairs of shapes. Make words matching each shape on the left with the same shape on the right to unlock the next level. After matching all shapes you can continue to find the rest of the words for a higher score or immediately move on to the next level.
