Color Block Jam Levels 401–800: A Hard-Level Planning Method

Where should you begin?

Start with a full-board scan. The official hard-level guidance emphasizes planning a few moves ahead and passing blocks in the right order. Turn that into a written list: immediately reachable exits, one-block dependencies, and multi-step traps.

How do you handle timed objects?

Treat a countdown as a priority constraint. Identify the minimum route that changes it, then avoid unrelated moves that consume the limit. If the count or object position differs from the video, use the mismatch page.

What is the best restart rule?

Restart as soon as the center is blocked without a fallback or a useful stopper has been cleared too early. Change the first dependency, then observe the next checkpoint.
