Addicting Game, but technical issues

When I saw the name Knizia, I had high hopes for this game. I was not disappointed. I haven't played the endless mode, but both arcade and level have a good amount of tension throughout the game. Both mix quick counting with longer term strategic planning. Of course, you could just have fun and play the first adding up that you find, but to advance further you need to plan more. The game can be a relaxing unwind or brain burner.

The only issue is that it crashed on me and it would not work until I completely deleted and reinstalled it.

Frequent freezes on iPad 4th generation

Freezes all the time. Repower iPad, save is some 30 numbers lower. Super annoying on endless mode.

Simple and Relaxing

A simple puzzle game that requires a little bit of planning and thoughtfulness. At first I was unimpressed, but as I played it more I came to see that it has a certain charm and that it requires some strategy. Overall It's pleasant and interesting in a low-key way, though it lacks any goals beyond just trying to stay alive and keep racking up points.

I would like Knizia to be a lot more ambitious with his iPad designs than this, but Yoku-gami does execute its one idea quite well. I give it a mild recommendation; it's definitely worth a buck or two if you're looking for a fun little number puzzle to keep you occupied, but if you want something flashy or exciting you might want to look elsewhere.
