## What is X?

X-Sudoku — Logic Puzzles Game

Train your mind with the most elegant puzzle game on the App Store. X-Sudoku offers hundreds of hand-graded puzzles across two distinct variants, built for players from first-timers to seasoned solvers.

Two Variants. One Obsession.

Classic 9×9 — The timeless grid. Fill every row, column, and 3×3 box with the digits 1 through 9. Pure logic. No guessing required.

X-Sudoku — An additional twist: both main diagonals must also contain all nine digits. 18 extra constraints. Entirely new strategies.

Five Difficulty Levels
From Easy (~10 min) to Epic (~45+ min), each difficulty unlocks as you progress. Whether you have a few minutes or a long commute, there's a puzzle for you.

Earn Points. Climb Titles.
Every solve earns points based on your speed, mistakes, and streak. Rise through 20 titles — from Student to Immortal.

Daily Challenges
A fresh puzzle every day. Solve it to earn bonus points. Keep a 7-day streak to double your daily rewards.

Perks System
Earn perks by solving puzzles: use a Hint to reveal a cell, Chance for an extra mistake, Forgive to wipe your record clean, or Double Points to maximise your score.

Clean. Focused. No clutter.
Elegant typography, a paper-toned palette, and smooth animations keep the focus on the puzzle.
