About this game

Sudosmith is Sudoku with a friend on the line.

RACE THE SAME BOARD
Challenge a friend by link, QR, or a short code. You both get the exact same puzzle,
dealt by the server, and solve it privately — first correct solve wins. Their grid
never shows: you see progress, boxes, and mistakes, never a single digit. No spoilers.

SOLO, YOUR WAY
Unlimited classic 9×9 boards at four difficulties — Easy, Medium, Hard, Expert.
Pencil-mark notes, an optional mistakes limit, and a quiet timer you can hide.

OPTIONAL CONTENT (FOREVER UNLOCKS)
Extra Grids: Mini 6×6, Mega 12×12, and Ultra 16×16 solo (hex digits 0–9 A–F).
Logic Variants on 9×9: Diagonal, Even–Odd, and Hyper. Difficulty is never paywalled.
Host needs a pack to create a pack race; guests always join free.

A CALM DAILY
One classic 9×9 board a day, the same for everyone — packs never touch the Daily
streak. No lives, no streak-freeze store, no pressure.

ON-DEVICE STATS
Best times per difficulty (classic-scoped), Daily streak, and your race record —
all kept on your device. No account. No leaderboard servers.

FAIR BY DESIGN
Free 9×9 forever. Guests always join free. Rematches never ad-taxed. No ads on wins.

Same board. Solve it first.
