1. Cats & Dogs: Tango's rules, unlimited boards
Cats & Dogs is our free daily puzzle with the same rules as Tango. You fill a 6×6 grid with cats and dogs. No three of the same animal can sit side by side, across or down. Every row and column holds three cats and three dogs. An = between two squares means the same animal, and a × means different ones.
Every board has exactly one answer, and you can reach it by logic alone. Our solver checks that before a board goes live. If you get stuck, Hint shows the next logical step and says why it works. There are three new boards every day: easy, medium and hard. It's free in your browser, with no app and no account.
Unlimited Tango: Endless mode
Looking for Tango unlimited? Endless deals a fresh board every time you finish one, at easy, medium or hard. It plays by the same rules as the daily boards, and you can keep going as long as you like. It's free and needs no account.
Every past board, and the answers
Missed a day? The archive keeps every Cats & Dogs board we have released, and all of them are still playable. If a board beat you, the solutions walk through each daily puzzle step by step, with the reason for every move. These are answers to our boards only. We don't publish LinkedIn's daily Tango answer.
