Pack 1
4×4 Level 1
A ⚡ OFF 🔋
B ⚡ OFF 🔋

Connect A → A. Tap to rotate 90°.

Taps: 0

How to Play

Create a fully functioning circuit board by connecting the power source to the battery.

  • Rotate: Tap any tile to rotate it 90° clockwise. Double-tap to quickly rotate 180°.
  • Energy Flow: The line will glow amber when it's actively connected to the source ⚡. Your goal is to chart the flow all the way to 🔋.
  • Perfect: Connect the matching terminals with fewer taps for a ⭐⭐⭐ rating!
  • Locks: Tiles with a 🔒 cannot be rotated. You must build your circuit around them.

Dual Source (Advanced):

In later packs, you must manage two distinct energy paths (Amber and Cyan) simultaneously. Some tiles like Crosses (╋) can carry both energies independently!

How to Play PipeLink

Rotate the circuit tiles to connect the circular source to the square destination with the same letter. Each tap on an unlocked pipe turns it 90° clockwise and counts as one rotation. Both sides of a shared edge must have matching openings. Lit channels show where power reaches. From pack 4, connect A→A and B→B at once; a cross carries its horizontal and vertical routes separately. Pack 5 adds fixed pipes. You do not need to power every tile. Stars compare your rotation count with a target based on unlocked non-cross pipes; they do not prove a shortest solution. Reset restores the initial board and tap count. Hint demonstrates a stored solution by rotating and locking pieces in sequence, then offers a restart. Five packs contain 125 levels.

Frequently Asked Questions

What are locked tiles?

Pack 5 includes locked tiles. Their orientation is fixed, so rotate the surrounding circuit instead.

What is Dual Source?

From pack 4, connect A→A and B→B simultaneously. Cross tiles keep the two channels independent.

How do levels and stars work?

There are 125 levels in five packs. Let N be the number of unlocked tiles excluding empty and cross tiles: at most 1.5×N rotations earns three stars, at most 2×N earns two, otherwise one. This is a scoring target, not a proven optimum.

What does the Hint button do?

Hint starts an automatic demonstration that rotates and locks pieces toward a stored solution. It can reveal several steps, not just one move. When the demonstration connects the circuit, a restart prompt appears instead of the ordinary scored-clear result. Use it to study the route, then restart to practise.
