With 4-5-6 Pro you get: 1, 000 puzzles- Unlimited Answers- No ads- Puzzle SelectorProgramming by Jayden Navarro. Graphics by Han Castanedo. IMPORTANT: The dictionary I'm using is not extensive due to lack of availability of word lists. All puzzles do have solutions though. If you enter a word that you know is a dictionary word don't worry, you're not going crazy. If you want to help improve the game for future players, send me an email and I'll collect all of the words I should include and then issue an update. Sorry for the inconvenience.
