Needs a timer
I really miss a timer. A second feature I love but can do without is a bookmark. The sales screen also states you can turn off certain features but no option exist in settings. Other than that for a free app it’s great. The ads are unobtrusive I intend to click on one occasionally to send some funds to the developer.
United StatesPretty good
If you have an undo button, you should also have a redo button. If you accidentally hit the button and don’t see what changed, there’s no way to correct your mistake. Challenging games.

United StatesBob
I like the game, but it keeps pausing, makes me suspicious
United StatesIt’s not bad, but...
The first game on the hardest, there was a glitch where the puzzle was incorrect in receiving the right entry. The creator of this game maybe is the glitch?
United StatesAwesome
Great game. Fun.& challenging!
United StatesLove it, but.....
I truly do love the game. However, there really should be some sort of game statistics available. Even something as simple as Number of games played, won, and lost.
