Signal
Tangle

A logic-and-control time attack where you release tangled signal lines in the right order.

Overview

Signal Tangle is a logic puzzle where curved signal lines flow out along their own routes. Lines that can escape disappear, while blocked lines return to their starting position. Color locks open after every matching line has exited, so later stages ask you to read the release order several steps ahead.

How to play

Goal

Release every tangled signal line out of the board.

Clear all

Clear all lines to finish

Flow along rails

Tap a line and it flows along its own curved route toward the outside.

Tap

Blocked lines return

Color locks

A color lock opens after every line of the matching color has flowed out.

Lock

Read the unlock order

Internal grid

The grid is hidden, but routing, collision, and density are controlled by it.

Structure

Later boards get denser

Time attack

There is no game over. Each blocked tap adds +10 seconds, and your clear time is the score.

Time

Avoid misses and read the order
