Tango Grid

Tango Grid is an online puzzle game and daily brain-training platform based on the popular binary logic grid puzzle. Players solve grids by placing sun and moon symbols according to simple yet challenging deduction rules: each row and column must contain an equal number of suns and moons, no more than two identical symbols may appear consecutively in any direction, and equality (=) or opposite (×) relationship clues must be strictly satisfied.

Tango Grid offers a daily set featuring three core puzzles plus two optional bonus challenges that refresh every day at midnight UTC. In addition to daily challenges, players can enjoy the Unlimited mode featuring multiple grid sizes—from beginner-friendly 4×4 and 6×6 boards up to advanced 8×8, 10×10, and 12×12 grids. A Timed mode delivers high-energy timed solving sessions where completing boards awards bonus seconds. With clean visuals, responsive touch and mouse controls, instant move validation, smart hints, and seamless local browser save, Tango Grid delivers a delightful logic puzzle experience without requiring downloads or account registration.
