Color Block Jam Stuck After a Good Start: What to Check

Why does a good opening still stall?

An opening can clear space without opening the dependency that controls the next route. The board feels close to solved, but one key, gate, or temporary stopper is still in the wrong order.

What should you check?

Mark the next destination, its required color, and the block that currently prevents access. If that blocker depends on another exit, work backward one more step instead of making a convenient move.

When should you restart?

Restart when the first mistake has closed a lane you cannot reopen. Before trying again, record the first mismatched dependency so the second attempt changes the plan rather than repeating the same opening.
