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. |

Before you play
What to do when a hard-level guide differs
A verified difficulty label does not prove that the walkthrough matches every version of the board. Confirm the level number and opening layout, then pause at the first checkpoint before continuing. If the state differs, keep the guide as a source lead and use the mismatch workflow.
