Color Block Jam Video Checkpoints: Verify a Walkthrough Safely

Which checkpoints matter?

Check the opening board, the first three moves, every major gate or chain transition, and the final completion state. These points confirm that the sequence and the board are still aligned.

The Level 275 example shows the useful pattern: a source link next to timestamped steps and a visible checkpoint description. You do not need to pause after every ordinary tap. Choose states that affect the next decision, such as a door opening, chain changing, counter reaching zero, or an obstacle being revealed.

Checkpoint	Compare	Meaning if it matches
Opening frame	Number, blocks, exits, doors, counters	The source begins from a comparable state
First meaningful move	Block position and changed counter	The early route is reproducible
Route transition	Gate, chain, or obstacle state	The next section has the expected dependency
Completion state	Final cleared board or signal	The displayed route reaches the shown result

Should you pause after every tap?

Not necessarily. Pause after a state change or when the video’s board becomes hard to compare. The purpose is to preserve a reliable visual checkpoint, not to slow down every ordinary move.

If the source is old, be more conservative. The official Help Center notes that updates can change a level after a video was recorded. That makes a checkpoint a safety stop, not a promise that a historical route applies to every player.

What if one checkpoint fails?

Stop at the first failed checkpoint. Verify the level number and layout, then use the mismatch workflow. Adapting later moves to an earlier wrong board usually compounds the error.

For a compact record, note the timestamp, the visible board change, and the next move that depends on it. This keeps a checkpoint useful when another player or editor needs to audit the route later.

How should you describe a checkpoint?

Describe only what the frame shows: which block moved, which exit or door changed, what countdown is visible, and what the next instruction depends on. Avoid claims about hidden state or a guaranteed result outside the displayed evidence. The source verification method is a useful companion when you are unsure whether a checkpoint is enough to call a page complete.

What should you do after a mismatch?

Return to the last matching checkpoint, check the current level number and opening layout, and use Wrong Level if the source no longer fits. Do not splice a later section from another video into the route. A short note with the timestamp and first difference gives an editor something reviewable.

When a checkpoint is visible but the written instruction is ambiguous, trust the frame boundary and record the ambiguity. A clear “unknown” is safer than translating a visual change into an exact move the source does not show. That standard keeps a complete guide distinct from a page that merely links to a video.

For a repeatable review, use the same checkpoint vocabulary each time: opening, first move, route transition, and completion. If a source skips one of those states, mark the gap instead of filling it from memory. This keeps the article useful for players, editors, and systems that need to quote only what the source visibly supports.

When you share a checkpoint note, include the source title and timestamp beside the observation. A reader should be able to return to the same frame and see why the next move was allowed. If that frame is unavailable, downgrade the claim to a source lead and keep the limitation visible.
