Sudoku Ladder
Reach your level, rise above
Free · Designed for iPad. Not verified for macOS.
Compete in Campaign mode against other player ghost replays, play sudoku endlessly on free play mode or simply do the Daily Sudoku grid
Solve the same puzzle simultaneously against the ghost of an opponent on an identical grid. Beat the grid and your 'Difficulty' rank increases. Beat the grid the fastest and your 'Speed' rank increases
THREE WAYS TO PLAY
Campaign: The ranked competitive mode where your rating rises with every win. Race opponents across 7 difficulty tiers. Win clean, and your solve becomes a ghost for future opponents to race against. Climb the leaderboard and find out what level of difficulty defines you.
Free play: Just the enjoy the game without stakes.
Daily Time-Attack: A new seeded puzzle every day at midnight UTC, identical for all players. Competing on a daily leaderboard or just do your daily Sudoku dose
A 2D RATING SYSTEM
Unlike traditional ratings, your score is measured in two independent dimensions:
- Dimension 1: Difficulty: How hard are the puzzles you solve? Race tougher opponents and unlock harder grids.
- Dimension 2: Speed: How fast do you solve them? Beat your competition on the clock.
Your position on the 2D rating plane determines your next opponent
