Where do these numbers come from?
From each market's own record. The block starts with the last declared ank and its cut, then adds the anks that have been most common lately. Jodis pair those anks, and one panna is chosen per ank.
Are they sure numbers?
No. They are a free pick that often misses, and the check table on the home page shows the misses too. Please do not pay anyone who claims to know a result.
How often do they change?
Once a day, just after midnight India time. A refresh will not change them, and â marks appear only after the real result.
