About Color Link

What is Color Link?

Color Link is a puzzle of coloured dots on a grid. Join each pair of dots of the same colour with a line that goes square to square, across or down, never on the slant. Lines never cross or share a square. When every colour is joined and every square has a line through it, the puzzle is solved. Every puzzle is made to have exactly one answer.

Questions

Is it free?

Yes. Nothing to sign up for: it plays in the browser at once. 160 of the 1,269 puzzles are free, and the rest come with the Lounge Pass or a ticket. Today's puzzle and its ranking are free too. Signed in with Google, tickets come free as a daily gift, for solving today's puzzle, and more.

Can I play on a phone?

Yes. In the browser on a phone, a tablet or a computer. Nothing to install.

Do I have to fill every square?

Yes. Here a puzzle is solved not only when every colour is joined, but when every square has a line through it. If the colours are joined and squares are still empty, try sending a line the long way round.

What is the Lounge Pass?

A subscription that takes the ads away in every game and opens everything that would need the Pass or a ticket. Here, all 1,269 puzzles. Without it, one ticket opens the next puzzles along a road (5 easy, 4 normal, 3 hard, 3 Oni or 2 master). ¥500 a month or ¥5,000 a year, tax included, with a 7-day free trial the first time. The first 100 founding members pay ¥300 a month or ¥3,000 a year, for as long as they keep it.

Does every puzzle have one answer?

Yes. Each puzzle is made so that only one way of joining fills every square. When stuck, look for a square that can only go one way because everything around it is taken - one step decides the next.

Can I see the answer?

While you play, a hint shows the way one line goes, one at a time - colours you have not drawn yet first. You can use up to half as many hints as the puzzle has colours.

What happens if I go wrong?

You are not told on the spot. A line cannot pass through another colour's dot, and crossing another line cuts it. When every colour is joined and every square is filled, it is right.
