Same logic as Sudoku.
Solved with letters, not numbers.
Every row, column, and block hides one word, spelled exactly once. One shared puzzle drops worldwide at midnight UTC — solve it clean and climb the daily board.
Pick your puzzle
Each mode changes the rules of engagement, not the core logic — so what you learn in one carries into the rest.
Daily Challenge
One puzzle, shared by every player, reset at midnight UTC. Speed, accuracy, and hint count decide the leaderboard.
Levels
Start at a 4×4 warm-up and work up to a 16×16 board. Each size unlocks once the one before it is cleared.
Wildcard
Type any word — a name, a pet, a team — and the grid is built around it on the spot.
Practice
No clock, no ranking. A quiet board for learning the patterns before taking on the Daily.
How a board gets solved
Learn the hidden word
Every puzzle is built around one word — its letters are the only pieces on the board.
Fill without repeats
Each row, column, and block must contain every letter of that word exactly once.
Tap to place
Select a cell, then pick a letter from the tray below the grid.
Mind your mistakes
Three slip-ups and the board resets — unless you revive and keep going.
Beat the clock
Faster, cleaner solves rank higher on that day's board.
