Hi there.
My grandma would fill notepad after notepad with this number game. We would ask her what is it or how does it work and she would say "oh it's just my little number game I play" and never once explained it to us. She's passed now, and I asked for these notepads in hopes I can figure it out. Her writing is...well as you can see, it's tough to read. But I have three notepads filled with this. Just hoping someone could help me understand what she was playing. Thank you.
