About this game
Copper Loop is a board of pipe, all of it pointing the wrong way.
Tap any tile to turn it a quarter turn. Keep turning until every pipe is joined
back to the source in the middle. Pipes light up the moment they connect, so you
can see the network growing on every single tap rather than only at the end.
YOU CANNOT LOSE THIS GAME
There is no timer, no move limit and no wrong turn that has to be undone - a tile
you turned the wrong way is fixed by turning it three more times. Nothing is
spent, nothing runs out, and no board can be ruined. That is not a difficulty
setting. It is what the game is.
Finish a board tidily and it is worth three stars, but a board you brute-forced
still finishes. The stars are there to go back for, not to keep you out.
HOW TO PLAY
- Tap a tile to rotate it one quarter turn
- Lit pipes are connected to the source; dark ones are not
- Finish when every pipe on the board is lit
- That is the whole rule set
WHY THE LIGHTING MATTERS
A grid of identical grey tiles is a memory test. Lighting the connected part
turns it into something you can reason about: the lit region is settled, the dark
region is what is left, and every tap moves the border between them. It is also
why this plays well in short bursts - you can always see where you were.
WHAT YOU GET
- Hundreds of levels, from a handful of tiles up to a board that fills the screen
- Dead ends, crosses, elbows and straight runs, mixed as the boards grow
- A hint that turns the next tile the right way round for you
- A daily challenge: one board, the same for everyone, every day
- Fourteen colour sets and twelve board designs to unlock as you play
- A level map, to go back for any board you rushed
