Our methodology

4D Data Sources & Verification

A result is only as useful as its source. This page explains the difference between newly observed reports, verified records and historical coverage.

Which results do we cover?

Go4D displays supported games from Magnum, Sports Toto and Da Ma Cai, together with selected Singapore, Sabah & Sarawak and Cambodia results. Not every game is published at the same time. Availability is shown per game; we do not treat one operator's draw as another operator's result.

How results are collected

Our system prefers official operator information when it is technically accessible. When an official source cannot be read reliably, it may use secondary publishers, including Check4D, subject to parsing, structure checks and corroboration. These secondary publishers may share upstream sources, so agreement does not guarantee independent confirmation.

Updates can be delayed while results are published and checked.

Provisional versus verified

Provisional

A newly observed feed report may appear with a provisional status while it awaits confirmation. Such results can be corrected. Some game types have different validation requirements.

Verified

Go4D applies format checks, matching draw identity and source comparisons before recording qualifying classic 4D results as verified. Verification reflects the evidence available to Go4D; it is not a warranty or a substitute for the operator's official publication.

When reports conflict or cannot be established, they may be held or shown as unavailable rather than presented as confirmed.

Historical data and number statistics

Historical records differ by operator. Selecting ten years does not mean every draw in that period is available. Hot & Cold rankings use available verified records only. Missing dates affect counts and rankings. The draw history shows data actually stored for the selected date.

Report a suspected error

Compare the draw date, game, draw number and prize positions with the official operator publication. If you notice a discrepancy, see Contact Us for what to include in a correction report. Do not use a provisional number as evidence of a prize entitlement.
