Sudoku ~ Classic Number Puzzle

I have been playing this game for many years, and it is the most creative of all the sudoku apps I’ve tried. Besides the daily master puzzles, I love to enter challenging puzzles from other sources, and complete them without paper erasures. I love the variety of colors, typefaces and grid styles. I also love the “rewind” function that enable you to scroll back to a possible error.

I am always disappointed that my rank goes back to beginner, when I have spent HOURS to achieve expert. Especially receiving the message “congratulations Beginner!” after completing my first game after the upgrade.

This version appears to have all the functionality of the previous version but with the buttons rearranged for no apparent reason, in some ways detracting from ease of use. The menu button is used every time a new sudoku is started. Why is it now off in a corner? Here’s my review of the previous version: This is an excellent sudoku app -- straightforward to use and just flexible enough, with sensible options and choices but no silly frills or add-ons. Works great on my iPhone SE, as its predecessor versions did on my ancient iPhone 5S.
