PopBack: Color Sort Puzzle

PopBack is a sleek, minimal code puzzle about sorting scattered color signal chips into slot lanes to restore the system's Signal Panel.

Forget generic bottles and tubes! Touch and transfer rounded chips to empty lanes or on top of matching chips. Gather 4 of the same signal chips in a single lane to complete a set, watch it absorb into the top panel with a bright glow, and instantly clear the lane for more sorting.

Challenge your logic and restore the circuits in the fewest moves possible!

[Engaging & Mind-Bending Gimmicks]
As you progress, unlock specialized obstacles that alter the rules of sorting:
- Locked Lane: A locked slot that only opens when you complete specific signal sets first.
- Blind Lane: Only the top chip's color is visible. Shift the top chip to reveal the hidden components underneath.
- Relay Node: Sequence is key. Sets must be resolved in a specific order, or completed sets will go into standby.
- Overload Chip: High voltage! These volatile chips cannot be placed onto a completely empty lane alone.
- Combined Challenges: Past Level 100, experience high-difficulty puzzles where multiple gimmicks combine to test your limits.

- Simple Tap-to-Sort Controls: Easily play with just one hand.
