About this game

Sumoku isn't just another sudoku. It's the Killer Sudoku that teaches you how to play — and makes you better with every grid.

Most sudoku apps just hand you the answer when you're stuck. Sumoku explains the reasoning: which technique to use, why this cell, how to break down a cage's sum. You stop guessing and start understanding.

▍ TWO MODES, ONE JOURNEY
- Killer Sudoku — add up the cages, deduce the digits, master sum combinations.
- Classic Sudoku — the timeless classic, from easy to expert.

▍ LEARN, THEN PLAY
Guided step-by-step lessons teach you every technique — from scanning to naked pairs and cage combinations — on real interactive grids.

▍ HINTS THAT TEACH
Our hints don't write the number for you. They name the technique and show you the logic. Out of hints? Earn a bonus one by watching a short video — your choice, never forced.

▍ DAILY CHALLENGE & STREAKS
A fresh grid every day, a calendar to track your collection, and missed days you can replay. Keep your streak alive and watch your consistency grow.

▍ BUILT FOR REAL PROGRESS
- 4 levels: Easy, Medium, Hard, Expert.
