Description
No ads. No guessing. Just pure-logic variant sudoku.
VariantDoku is built for solvers who want more than one daily grid — a growing library of 1,800+ variant and zero-givens puzzles, every one verified to have a single solution reachable by logic alone. No ads, ever — free or paid.
WHY SOLVERS STAY
1,800+ variant & zero-givens puzzles: killer cages, thermos, kropki dots, XV, arrows, renban, German whispers, palindromes, diagonals, anti-knight, and more
Every puzzle is logic-checked: one unique solution, no guessing required
A new daily puzzle, free for everyone — compare solve times on the daily leaderboard
Home-screen widget keeps today's puzzle one tap away

TOOLS THAT RESPECT YOUR SOLVE
Candidate notes, corner marks, colors, and symbols for advanced solving
Error checking and gentle hints — only when you ask
Import puzzle links straight into your Library
Search and filters by difficulty, grid size, and constraint type
Streaks and solve history to track your progress
Dark mode and a calm interface designed for long sessions

HINTS THAT COACH, NOT ANSWER
Every hint names the next logical step — Hidden Single, X-Wing, W-Wing, Simple Coloring, Forcing Chain — and highlights the cells it depends on
It reads the pencil marks you already made and builds on them
It never reveals a digit that isn't logically deduced; when the logic only rules candidates out, it shows you that instead of handing you a number

Classic Sudoku, Killer Sudoku, Kropki, XV, Thermo, German Whispers, Renban, Palindrome, Between Lines, Lockout Lines, Region Sum Lines, Arrow Sudoku, Diagonal (Sudoku X), Anti-Knight, Anti-King — plus multi-constraint puzzles that combine several on one board, and zero-givens puzzles solved entirely from the variant rules.
