Deep Sudoku: Endless Depth

Abyss Night: a spooky Halloween theme and a new jack-o'-lantern app icon, until November 3!

Deep Sudoku is a sudoku that keeps unfolding.

Begin with a 2×2 spark, solve a 2×3, then a glowing 3×3 core. From there the board opens box by box — the center grows into a full 9×9, and two wings grow from its corners until three boards share one hidden solution: the Crown.

• Always moving forward — every solved box stays and binds the next • One true solution per stage, generated fresh for every Depth • Endless Depths that get gently harder, four difficulty levels • A calm, deep-sea design with 3D boards, zoom and motion parallax • Stars, celebrations, badges, Core Crystals and collectible fragments • Replay any finished stage to beat your best • Game Center leaderboards and achievements • English and Turkish
