Your goal is to fill the grid with symbols (Hearts, Spades, Diamonds, Clubs) while obeying three strict rules. No math is required: just pure logic. GAME FEATURES Infinite Logic Challenges From quick 4x4 warm-ups to massive 12x12 Expert grids, there is a level for every mood. Whether you have 2 minutes or 2 hours, DUO keeps your brain sharp.
