Color Block Jam Deadlock Signals Before It Is Too Late

Which signal appears first?

Often the first signal is not a total stop; it is the loss of a lane or staging space that several routes share. Mark it before the board becomes impossible to read.

What should you do immediately?

Stop adding moves and identify the last change in access. Undo that move if it caused the signal, or restart from the last checkpoint.

What makes a route trustworthy?

Each major move should have a named destination or dependency. A sequence that only keeps options “maybe open” is already at risk.
