How to Play Boundary Color Edge Blocks

Core rules, common block shapes, and practical strategies to help you clear the board faster.

Basic Rules

The board in Boundary Color Edge Blocks is made up of colored blocks fitted together, each marked with a directional arrow on its surface or edge. There's one rule: blocks that share a color and an arrow direction clear automatically once they're adjacent.

How a block moves depends on its arrow:

A block marked ▲ can only slide up.
A block marked ▼ can only slide down.
A block marked ◀ can only slide left.
A block marked ▶ can only slide right.
Some blocks carry a two-way arrow (such as ◀▶) and can slide in either direction along that axis.

Blocks aren't always simple squares — some are long bars spanning two or more cells, and others are L-shaped or T-shaped, covering an irregular footprint. When moving these, make sure every cell the block occupies is clear in the direction you're sliding.

Strategy Tips

Start at the edges, then work inward

Blocks along the border usually have more room to move, since they sit closer to open channels. Clearing edge blocks first often opens up space for pieces stuck in the middle.

Matching color doesn't always mean an instant clear

If two same-colored blocks point in different directions, you'll need a few moves to reposition one of them before they can slide together and clear.

Save large blocks for last

Bigger, irregular shapes (T-shapes, L-shapes) tend to be tied up with more of the board. Clear smaller and bar-shaped blocks first to simplify the layout before tackling these "structural" pieces.

Pace yourself on timed levels

On levels with a countdown, resist the urge to try every option immediately. Spend a few seconds reading the full layout and plan two or three moves ahead before you start — it's usually faster than moving one step at a time.

Stuck? It's usually the order, not the puzzle

If the board locks up after a move, the issue is almost always move order rather than an unsolvable position. Try undoing your last one or two moves and picking a different block to work from.
