Where the numbers come from

Singapore Pools publishes results on its website, and its terms prohibit automated collection and restrict reuse. Drawology therefore does not scrape anything, and it shows real historical results only once it has written permission, a licence or legal clearance for that use. Until then, the site runs on clearly labelled simulated draws.

How results are validated

  • Every import is a new batch with the source URL, a SHA-256 of the exact file and the time it was fetched.
  • 4D: exactly 23 prizes per draw (first, second, third, 10 starter, 10 consolation), each four characters, leading zeros kept.
  • TOTO: six distinct winning numbers plus a separate additional number, within the range for the rules in force on that date.
  • Draws with placeholder dates, missing numbers or impossible values are quarantined and listed, never silently fixed.
  • TOTO moved from 6/45 to 6/49 in October 2014. Engines use only 6/49 draws, since earlier draws come from a different set of numbers.
