Ratings and reviews

I love sudoku challenge 16x16 and this is the best app I've found so far. However, I rated this app with only 3 stars because the biggest problem for me is that the colors of the grid make the numbers and letters so hard to see. It's hard to work on a puzzle when you have to squint your eyes just to read the chart. However, if this problem can be fixed I will happily change my rating.

Disappointed that I am unable to save my game when I have to stop part-way through. I have tried the "field-save" functions and they don't work consistently. There are no instructions on how to save a game. Also I would like some error-checking function. Sadly, I will uninstall this game.

For a game that advertises itself as 16x16, it is frustrating that 16x16 boards are locked until you prove yourself on 9x9 puzzles first. I downloaded this game because I already know I can handle 16x16 and am bored by 9x9 puzzles. They are no longer challenging for me. Doesn't have the convenient features I've grown to love in other sudoku apps, such as removing penciled-in entries once you've decided on a match somewhere else in a row.
