Sudoku IQ+: Solo & Multiplayer

Solve with focus. Compete under pressure.

Sudoku IQ+ brings serious solo puzzles and competitive multiplayer Sudoku together in a completely redesigned app. Explore nine game modes, follow your progress and find a new reason to return each day.

SOLO PLAY WITH DEPTH
Choose Classic, Mini 6x6, X-Sudoku (Diagonal Sudoku), Killer Sudoku, Timed Sprint, Story Mode, Chaos Mode or the Daily Challenge. Multiplayer completes the nine-mode line-up. Use difficulty levels, pencil marks, highlighting and undo/redo to support your solving.

SEE THE RACE UNFOLD
Race a matched opponent while coloured-cell progress and a completion percentage update live. See the pressure build without revealing answers or the exact cells your opponent has solved. Matchmaking prioritises available players and supplies an AI opponent when no player is available. Friend invitations are not currently supported.

DAILY CHALLENGES AND WEEKLY TOURNAMENTS
Multiplayer, daily challenges and weekly tournaments are available from level 1. Build your streak, follow leaderboard results and take on four tournament puzzles each Thursday–Sunday.

TRY VARIANT LAB
Play the featured Chaos, X-Sudoku or Killer challenge at any level, even before that mode's normal unlock. The offering follows the daily schedule; it is not unrestricted access to every locked mode.

UNLOCK MORE THROUGH FREE PLAY
Play unlimited puzzles in unlocked modes. Mini opens at level 2, X-Sudoku at 5, Killer at 15, Chaos Mode from 18 and Story Mode at 20. Additional Chaos variations may require higher levels.

A FRESH LOOK, WITH 17 THEMES
Every screen has been redesigned with clearer navigation and a refreshed puzzle layout. Two new themes bring the total to 17: 11 available through free play and progression, plus six Premium themes.

FREE PLAY AND PREMIUM
Enjoy one ad-free puzzle each day. Ads may appear before other puzzles; optional rewarded ads support hints or continuation after mistakes. There is a three-hint cap. In multiplayer, hints and mistakes affect your match time. Premium unlocks all modes immediately, removes ads and offers an unlimited-mistakes setting; multiplayer time penalties still apply.

TRACK YOUR SUDOKU PROGRESS
Follow your results, streaks and Sudoku IQ score. Sudoku IQ is an in-game performance score, not a standardised intelligence test.

The app interface is currently available in English.
