How It Works
The cut pairs are 0-5, 1-6, 2-7, 3-8 and 4-9. Add five to a digit and keep the last digit: 7 + 5 = 12, so the cut of 7 is 2.
Just for fun. Nothing here can tell a result in advance, so never pay anyone for numbers.
Each ank has one partner five places away, called its cut. Type your digits to see them.
