About
Battle Sudoku takes the puzzle you already love and turns it into a duel.
The board is a Samurai Sudoku — five 9x9 grids that overlap into one 21x21 puzzle. The centre grid shares its corners with the four around it, so a single number can ripple across the whole board. It's the same logic you know, with a lot more room to think.
SOLO
Sit down with a fresh puzzle any time. Pick your difficulty from Easy to Expert, use hints when you're stuck, pinch to zoom, and pick up right where you left off. No timer breathing down your neck unless you want one.
ONLINE BATTLE
Challenge a friend to a live 1v1 race, or get matched with someone across the world. You both solve the same board at the same time and watch each other's progress fill in. First to finish cleanly wins.
STICKERS
This is where it gets personal. During a battle you can fling a sticker across your rival's screen — a laughing oni, an ink dragon, a lit smoke bomb — that blurs their board and breaks their concentration for a moment. Every sticker is hand-drawn in a sumi-e ink-brush style and animates with its own sound. A well-timed taunt wins games.
