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
02
Flow along rails
Tap a line and it flows along its own curved route toward the outside.
Tap
Blocked lines return
03
Color locks
A color lock opens after every line of the matching color has flowed out.
Lock
Read the unlock order
04
Internal grid
The board is built on an internal grid. Tapping near a line selects the nearest line.
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
