Pixel Flow Level 678 Walkthrough

Level 678 presents a tricky little puzzle featuring a classic voxel-style mailbox. At first glance, it looks cute—a maroon postbox with a yellow envelope symbol sitting on a wooden post in some grass. Don't let the charm fool you. The board is tightly packed.

The main challenge here is the heavy layering of White blocks surrounding the central mailbox, combined with two massive Ice Blocks in the top corners (labeled "450"). You need to clear the white "air" around the mailbox to access the actual structure. This is a very hard level because the Ice Blocks restrict the top corners, forcing you to be extremely precise with your pig management in the bottom half first.

Pixel Flow Level 678 Overview

Think of this level as a suburban scene. In the center, you have a maroon mailbox standing on a brown wooden post. Inside the mailbox face, there’s a distinct yellow envelope icon against a dark grey background. At the base of the post, there's a small patch of green grass.

However, the "air" around this mailbox is solidified into white cubes. This white layer acts as a shell, completely encasing the sides of the mailbox.

• Top Corners: Dominated by two giant Ice Blocks (450 HP each). These are practically indestructible early on. Ignore them.
• The Shell: Thick columns of white cubes flank the mailbox on the left and right.
• The Core: The mailbox itself is a mix of maroon (frame), dark grey (slot), and yellow (envelope).
• The Base: A single row of maroon bricks runs along the very bottom edge of the board, acting as a floor.

The asymmetry here is subtle but important. The white columns are your primary obstacle. Until those are thinned out, your colored pigs (maroon, yellow, brown) can't reach the inner layers of the mailbox.

First Color Zone to Erase in Pixel Flow Level 678

I start by targeting the White zones immediately. Specifically, look for the vertical white columns on the left and right of the mailbox.

Here is the logic: The white cubes are the "wrapper." The juicy center (the mailbox) is blocked by them. If you try to send Maroon or Yellow pigs early, they might hit the few exposed blocks on the front face, but they will likely run out of valid targets quickly and clog your slots because the side layers are still covered in white.

Grab a White pig as soon as it appears on the belt. Let it shred the vertical white columns. This exposes the side profiles of the mailbox (which are maroon) and the wooden post (brown). Without clearing the white first, you are playing blind.

Warning: Do not waste ammo trying to hit the Ice Blocks at the top. Your pigs will naturally hit them if there are no other white blocks, but don't prioritize them. Focus on the white pixels that are touching the colored mailbox.

How to pass Pixel Flow Level 678 without power ups or boosters

Once the white wrapper is significantly reduced, the board looks messy. You'll see jagged edges of the maroon mailbox and the brown post exposed.

Now, shift your priority to Maroon and Brown.

1. The Bottom Floor: There is a solid strip of Maroon blocks at the very bottom. A Maroon pig here is high value because it can clear that entire bottom row plus the frame of the mailbox. This clears up a lot of board space.
2. The Grass and Post: The Green grass and Brown post are deeply recessed. You usually have to clear the white surrounding them first. Once the white is gone, a Brown pig can easily take out the post.
3. The Yellow Trap: The yellow envelope is in the dead center. It is the hardest part to reach. Do not pick up a Yellow pig until you have a clear line of sight to the center of the mailbox. If you pick a Yellow pig while the maroon frame is still intact, that pig will sit in your slot doing nothing, waiting for a hole to open up.

In the mid-game, your board often gets clogged with partial layers. If you see a Grey or Black pig, check the mailbox slot (the dark opening). It's a small area. Only pick those pigs if you see the dark grey pixels are actually exposed. Otherwise, let them pass.

Last Details You Clean Up in Pixel Flow Level 678

The end game usually leaves you with the stubborn inner core of the mailbox. Typically, the Yellow envelope pixels and the Dark Grey slot pixels are the last survivors.

At this stage, the massive Ice Blocks at the top might still be lingering, or partially cracked. Don't panic. The level ends when the art is cleared, not necessarily every single ice block (unless pixel blocks are hidden behind them, which is rare for the main structure).

Your final moves will likely involve:

• Waiting for that one specific Yellow pig to clear the envelope symbol.
• Cleaning up stray Green blocks from the grass that were hidden behind the white shell.
• Watching your ammo count. If you have a pig with 1-2 ammo left and no targets, it will despawn. Make sure you don't fill your 5 slots with "almost empty" pigs that can't fire because the colors are buried deep.

Keep the rhythm fast, focus on peeling the white wrapper first, and the mailbox will open up for you.
