Challenging puzzles, easy to use, but eats the battery

I like the competitive option because it allows me to see if I'm improving. There are two significant problems, however. The first is that when playing the game the time of day and remaining battery life, which are otherwise omnipresent, are not shown. The second is that it consumes so much energy that even when my iPad is plugged in, the amount of battery life remaining decreases, which indicates that it is consuming a large amount of energy; an app that only responds to user input, and maintains a timer should utilize very little energy and the fact that it uses a lot makes me wonder what it is actually doing.

Question marks

Great game. It would be even better if you fix the question marks so it will always go to the last position regardless of how many numbers you type. The online version does that automatically, but lately the whole puzzle shifts to the center of the screen as soon as you enter a number. On the iPad it means that you cannot see the number bar anymore. Very frustrating issues with an otherwise fun game. Hope you can fix it.

Also, it would be helpful if the question mark is farther away from the 5. Hard when you use forefinger and thumb.


Easy to work. Good app for play. I would maybe want some other symbols to keep up with some numbers. Say underlining numbers when you deduce their place in a cube line to rule them out in other parts of the line.
The only real trouble I have with the app is the credits they give you when you reach certain goals. (Example: solve 10 hard puzzles, receive credits.) Except the credits are not given for A LOT of the goals. But if you really want some help with a sticky puzzle, you can buy some credits to help you out. Great for them. Not so great for you.
