The Safest First Move in Color Block Jam Puzzles

What makes a first move safe?

A safe move creates access or confirms a dependency without consuming the only open lane. Prefer a move with a visible follow-up rather than one that merely removes a block from view.

What should you scan first?

Check every exit, the narrowest lane, and any key or gate that appears to control several blocks. If a guide is available, compare its opening board before copying its first move.

What is the common beginner error?

Many failed openings clear the largest block because it looks important. Size is not priority; route dependency is. Use the first blocked destination to decide what matters.
