This is a battle of logic, endurance, and pure focus. Only the most determined minds can conquer these intricate grids.

About the Extreme Level

Extreme puzzles push logic to its absolute limit.

There are no starting clues — solving requires mastering multiple advanced strategies from the very first move.

Perfect for experienced players who want a true test of mental strength.

Extreme-Level Recommendations:

At the Extreme level, solvers commonly use techniques such as Unique Rectangle, 3D Medusa, and Coloring chains. These methods require tracking candidates across multiple cells simultaneously and are rarely needed in easier levels.
