Sudo6iX app for iPhone and iPad

Note this app contains no ads or in-app purchases !
This is a fun app that is based on a small size version of Sudoku ,with the addition of diagonals (hence 6iX). It is not difficult to complete ,but can be tricky at times ,so the app allows for help in these cases.
Examples of this type can be found in periodicals and newspapers such as the Daily Mail, and the app allows you to enter these and solve them with your input.
This is an ideal little puzzle for sharpening the brain on a short bus or train journey.
Compatible with iOS 8 .Designed for iPhones but will run in iPads as well.
