Flow Fit - Word Puzzle comes from Big Duck Games LLC, the makers of the famous Flow series.
The graphics are great. The puzzle sets have themes. I've solved about 50 levels in the easy, medium & hard modes.
A lot of puzzles are free. But the ones to purchase: too pricey. There should be just one price, say $5.
Many of the puzzles have been created by various accomplished wordsmiths. I like that the individuals are named.
