1. From one game to the next, words are often repeated, which becomes annoying instead of fun.
2. There is no way to end a game if you haven't solved all four words. You can close the app, but when you try to start over, it returns to the unfinished game.
3. The game would be more fun if the app included a link to something like the Anagram Solver app, so that if you decided to give up on a word, you could easily see option(s) you missed. I've downloaded the Anagram Solver app, and I do refer to it when I'm stumped, but it's a pain because you have to close down the Word Jam app, open the Anagram Solver, find the answer, close down the Anagram Solver app, reopen the Word Jam app, and finally correct the word left unsolved. TOO MUCH LIKE WORK.
There are other worthwhile suggestions among the listed reviews. Someone should be taking note of them. Thanks!
