When I’m stuck and receive hints they are numbers that do not go in the correct order told when ..

In some cases you can wrap the last number on a row to the 1st number on the next row

The rules are very cut and dry. Any two numbers either a match or a match equaling 10. Examples . 2 number fours either vertical horizontal or following in the same row with no numbers between as well as two numbers equaling ten such as 6+4 or 8+2. The easiest way to following the numbers at the bottom corner of the square is to tilt your phone following the trajectory of the number until it meets it's mate as long as no numbers interfere in between. Each row from bottom left to top right the first numbers if they match totaling ten but cannot go in reverse. The very first number The top of the board and the very last number at the bottom of the board as long as they match or equal ten. If they're is rocks in-between it counts as the end of the line even in the middle which is what makes it much harder to complete
