Quartix

Match every edge. A quiet, deliberate puzzle. Each block is split by an X into four numbered triangles — adjacent blocks must share their touching numbers. Start with a 2×2 grid. Master the 3×3. Brain-bend on a 4×4. In Hard mode every block is also randomly rotated, so you solve for position AND orientation at the same time. FEATURES • Three grid sizes: 2×2, 3×3, 4×4 • Easy or Hard difficulty • Drag or tap controls — works the way you think • "Match helper" highlights every compatible number • Live timer and move counter • Best scores per (grid size × difficulty) GAME CENTER 12 leaderboards and 14 achievements.

Your time stops with you. DESIGNED FOR FOCUS Light or dark mode. No ads. No interruptions. Quartix is for the moments you want to think.
