Camera Sudoku is for the puzzler wanting to understand the logic behind each solution entry. The systematic approach of five strategies, each with several methods, allows you to display every step in solving puzzles. Discover "Twins" to more quickly solve moderate puzzles. Understand Unique Rectangles and Chains for those pesky hard puzzles. HELP screens describe each method and include "screen shot" examples and the logic behind each method . One level of "UNDO" assists with "seeing what happened". And TWINS are optionally displayed for those puzzlers familiar with this solving technique. Puzzles can be entered with camera, photo album, or manually; can be saved, recalled, deleted and reordered. Text only or highlighted cell hints. "Possibles" or mini entered with a swipe. AND you can even solve 'em manually ! No Ads ! No in-APP-purchases !
