I like the various options for play, whether it is selecting a single cell and adding multiple notes, or selecting particular number and easily entering it into multiple cells, either as notes or solved cells. What I DON’T like is how the game “locks” cells once a number has been entered. You are prevented from adding a note to a solved cell, and you must remove the number in order to add the note, which makes sense. But what doesn’t make sense is that you CAN enter a different number into an already solved sell, overwriting the number already there. This means that you can inadvertently place a number in a wrong cell by accident when playing against the clock, and you may not realize it until the puzzle crashes and you can’t solve it. You have to try to go back and see what you did wrong, or more frustratingly, restart the whole game. Either way, your time score gets ruined. Next, I often find that, when trying to switch between entering notes and entering numbers, touching the toggle button doesn’t register, so I either end up entering the opposite of what I expected and have to stop and fix it, or the game thinks I touched some “blank space” around the puzzle and opens up the bottom menu, which prevents continuing game play until you close the menu, but the game clock still continues, again destroying your time score. Finally, the leap from Hard level games to Expert level is beyond exponential and doesn’t provide the same degree of advancement as between the other levels. Speaking of the Expert level, more than half of the games that I have played recently have required Trial And Error to solve it, which is not an appropriate solution method. One recent game even did it on a cell with three notes in it, which is an insane amount of trial and error. Lastly, if you are interested in tracking your scores against others, know that it is possible to cheat. Look at the global score board, and you will see games that have been completed in seconds, which is impossible, unless you take a screen shot, pause the app, solve the game offline, then go back and enter the solution. Not sure there is any way for the developers to prevent this, so it is more of an annoyance than anything else. With all of that said, I have enjoyed this app through all of the lower levels, despite some of the technical issues, but once you get good enough at the Hard level, I wouldn’t bother to continue.
