Block Out Levels 301-400: Advanced Level Log

By the 300s, the board stops feeling like a collection of separate routes and starts feeling like one shared traffic system. There are more blocks than comfortable open cells. A block parked in the wrong place does not just block one route; it can change the order in which every remaining color has to move.

This is the Advanced tier, and the main skill it asks for is restraint. The satisfying move is often the one that fills the center. The correct move is often the smaller one that keeps the center available.

The Advanced shift

Three changes define the 301–400 stretch:

• Less slack. Early boards let you park a block and forget it. Here, every parked block costs a lane.
• Longer route chains. One color may need to move in stages, using a temporary cell before its final approach.
• More expensive mistakes. A wrong move does not always end the level immediately, but it narrows the remaining options enough that the finish becomes a grind.

The three-pass scan still works, but the space pass becomes the most important one. Check where a block can wait before you check where it can go.

What to do when the board is almost full

A nearly full board is not automatically a dead board. Count the open cells and trace each remaining block's full route. If one complete route exists, use it. If no complete route exists, restart.

Do not judge space by the number of empty cells alone. Three connected cells in the center are more valuable than ten disconnected cells around the edges. The question is whether the empty space connects the block to its door.

Temporary parking

Advanced boards often require you to move a block out of the way without immediately sending it through its door. This is temporary parking. The rules are simple:

• Park at the edge, not in the center.
• Never park directly in front of a door.
• Never park in the mouth of a lane another color needs.
• Remember which block you parked and why. A forgotten parked block becomes a permanent blocker.

If you cannot name the move that will unpark the block later, do not park it yet.

Boards worth opening first

Level 344 is the most-watched board in this range and a good example of the Advanced pattern: the board looks open until one route is filled, then the remaining colors become interdependent. Compare the first move in the video with the move you would have chosen.

The range also contains a gap: Level 339 has no published level page yet because the playlist does not include a video for it. The linked index below naturally skips it. If you are searching for that exact board, the strategies in this log and the beginner guide still apply, but there is no embedded walkthrough to follow.

A rule for tight boards

When two moves look equally good, choose the one that leaves more connected open space. A move that clears a block but splits the open area into two small pockets is usually worse than a move that clears less but keeps one usable lane intact.

This is the habit that carries into the 400s, where the center becomes even less forgiving. The linked index below lists every available level page in 301–400.
