Verification method
How this hard-level list is verified
This page lists only Color Block Jam guides with visible in-game difficulty-label evidence. A level is added when a public gameplay frame connects the level number to a Hard or Very Hard label, then the source URL and checked date are stored in the evidence register.
| Standard | Evidence required | Why it matters |
|---|---|---|
| Visible label | The source frame must visibly show Hard or Very Hard in the game UI. | Difficulty is recorded from the gameplay frame, not from a player comment or title alone. |
| Level identity | The source must show or name the same Color Block Jam level number used by the guide page. | A label is useful only when it can be connected to a specific level page. |
| Review timestamp | Each entry stores the source URL, timestamp, and checked date. | Readers and crawlers can verify when the evidence was last reviewed. |
