How to Annotate a Color Block Jam Board Step by Step

What should labels represent?

Use short labels for each color and destination. Mark a key with the gate it affects and circle lanes used by more than one route.

How should arrows work?

An arrow should mean “this must happen before that becomes accessible.” If an arrow is only a guess, mark it as uncertain and test it with a reversible move.

When is the annotation complete?

Stop when the next move and the next checkpoint are clear. A crowded diagram can hide the dependency it was meant to reveal.
