Tango Game is a small independent project from Taiwan that creates a free daily Tango logic puzzle playable in any web browser. Each day brings a new grid to fill with suns and moons: every row and column must hold an equal number of each, no more than two of the same symbol may sit side by side, and the = and × clues between cells must be respected.

We design and test every puzzle so it can be solved by pure reasoning, with no guessing required. The game works on phones and computers, with no downloads, no accounts and no paywalls, so anyone can enjoy a few calm minutes of focused thinking.

Our vision is to make thoughtful brain games accessible to everyone and to turn a short puzzle into a healthy daily habit. Over time we hope to grow a library of high-quality logic puzzles and a friendly community of daily solvers.
