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.

Love the game and challenge. One improvement that would be awesome is if you would allow a "lock" paired squares/ in red or something. For instance if you have identified two squares in the same box or column that are 3/8 for example- you could highlight this "paired" sequence.

Unless I am missing something, this appears to offer a small number (at most 30) of 16x16 Sudoku games, most or all of which are locked in levels 2 and 3, which presumably unlock once you play through level 1, which starts as 9x9, and may be all 9x9 - there seems no point in me trying to find out when the Vistalgy Sudoku app, even tho it doesn't advertise itself as 16x16, already has excellent 16x16 games (in both standard and variant versions, at your choice of difficulty level, etc).
