À propos de Tango

Tango is a daily binary-placement puzzle that is easy to learn and surprisingly deep. Each grid starts with a handful of suns and moons already placed; you complete it by filling every cell so that three simple rules hold: no three identical symbols may appear consecutively in any row or column, every row must contain the same number of suns and moons, and every column must too. What looks like trivia turns into a lovely constraint web — one forced placement cascades across the board and suddenly half the grid resolves itself. Tango offers four board sizes and a daily official puzzle for each, plus hints and mistake checking so newcomers are never stuck for long. The clean, high-contrast board is readable at a glance on desktop or phone, and everything runs in the browser for free: nothing to download, no account needed. If you enjoy Sudoku, Tango or Takuzu-style grids are the perfect next daily habit — logic you can finish in five minutes that still makes you feel clever.
