I see numbers in rows and then they change direction every 10...

So... 0 to 9 go from left to right and 10 to 19 go straight up... then 20 to 29 go across from right to the left... and then it repeats...
Ok >>> So longer numbers do the same but stay in pairs...

I remember phone numbers in groups of three. Like 826 456 121
