The Curtain is hiding the level from you.
That is the whole problem. You are not playing the full board yet. You are playing the tiny part the game lets you see, while the real pixels sit trapped behind folded Curtain sections. If you waste piggies before those sections open, the level gets tight fast. Then the waiting slots fill, the wrong colors pile up, and suddenly the board that looked simple turns into a full jam.
The Curtain is not decoration. It is a color-cost blocker.
You pay that cost by clearing the color shown on the visible Curtain section. If the Curtain shows 20, that section needs enough matching pixels cleared to drop the counter to zero. Once it opens, the next hidden section becomes playable, and the board gives you the next part of the puzzle.
Piece by piece. Section by section.
The Curtain is a blocker feature that covers pixels behind it. You cannot use those pixels until the Curtain section opens.
Unlike a normal blocker, the Curtain does not pull up just because you clear blocks near it. It has a specific color demand. The visible Curtain section shows the color and the number you need to work on.
So if the Curtain asks for Purple 20, you need to clear purple pixels. If it asks for Pink 20, pink pixels matter. The number falls as matching pixels disappear from the board.
When the counter hits 0, that Curtain section opens.
Then the real headache starts: the next section becomes the target.
That means Curtain levels have a forced order. You cannot clean the board however you want. You have to follow the Curtain’s color path, or you will burn piggies that should have been saved for later.
Here is the clean rule set:
The Curtain hides the pixels you need later.
That sounds obvious, but it changes every move. In normal Pixel Flow levels, you can usually scan the board and judge if a piggy has enough matching pixels. Curtain levels mess with that. A color may look scarce because most of it is hidden. Or a piggy may look useless now but become perfect after the next section opens.
So the level is baiting you.
A Purple Pig might be sitting at the bottom, but if only a few purple pixels are currently open, sending it too early can create leftover ammo. A Pink Pig might be important for the next Curtain section, but if you waste it before that section appears, you may not get another clean chance.
That is how the Curtain kills runs quietly.
Not with one big mistake. With small sloppy taps.
The danger comes from four things:
Curtain levels are usually very hard because they combine limited vision with strict color timing.
The Curtain tells you the path.
Do not fight it.
If the current section asks for a color, that color is your priority. Other colors are only useful if they help expose more of the required color or keep your queue from breaking.
A common bad move is clearing whatever color has the biggest open patch. That feels productive, but it may do nothing for the Curtain. Worse, it can remove pixels that you needed as support for later piggies.
Good Curtain play looks like this:
That last step matters. After each Curtain section opens, the board changes. New pixels appear. New colors become useful. A piggy that was bad ten seconds ago may now be perfect.
Do not autopilot.
The number above a piggy matters more in Curtain levels than almost anywhere else.
If a Purple Pig has 20 ammo and the current Curtain asks for 20 purple pixels, great. That can be clean if 20 purple pixels are available.
If a Purple Pig has 40 ammo and you can only see 20 purple pixels, that is dangerous. The pig may open the Curtain, but then it still has leftover ammo. If the next reveal does not show more purple, it can land in a waiting slot and sit there.
That is bad.
The Curtain makes this tricky because hidden pixels might appear after a section opens. So a 40 pig is not always wrong. It is wrong when you cannot see enough same-color pixels outside the current section and you have no reason to expect more behind the next reveal.
Use this quick check:
The best players are not just matching color. They are matching color plus ammo.
