## What is EGK Sudoku?

EGK Sudoku 2026 is the most visually stunning and feature-rich Sudoku experience ever built for iPhone and iPad. Reimagined from the ground up for 2026, this is far more than a classic number puzzle. It is a full logic gaming platform wrapped in a sleek dark UI designed for serious players and curious beginners alike.

Killer Cages — cells are grouped into cages, each with a target sum. Logic meets arithmetic.
X-Sudoku — both diagonals must also contain numbers 1 through 9, adding an extra layer of challenge.
Miracle Sudoku — chess-inspired constraints where knight and king moves cannot repeat. Ultra-rare and highly rewarding.
Sandwich Sudoku — numbers between 1 and 9 in each row or column must sum to a clue. Elegant and mind-bending.
