Letters where the numbers used to be.
WODOKU is Sudoku made of words. Solve the grid with logic; as the orange cells fill in, the hidden word appears. Spot it early and grab the bonus.
For iPhone. In English, Spanish, German, French and Turkish.
Learn the rules in a minute.
Every puzzle hides a word whose letters are all different. You fill the grid with those letters.
Once per row
Each letter of the word appears exactly once in every row.
Once per column
The same letter can't appear twice in a column.
Once per box
Every box marked by bold lines also holds each letter once.
Orange spells the word
Read the numbered orange cells in order and the hidden word appears.
Hard really is hard.
Every puzzle has a single solution and can be solved by logic alone, without guessing. The level is set by the technique you need, not just the size of the grid.
Easy 6×6
Spotting that a letter fits in only one cell is enough.
Example: BADGER, FALCON
Medium 8×8
You'll need to notice when a letter in a box is locked to a single row.
Example: FLAMINGO, CHIPMUNK
Hard 9×9
You won't get far without pairs and hidden pairs.
Example: DRAGONFLY, EDINBURGH

Hints show the way, not the answer
When you're stuck, a hint explains the reason before it reveals a letter. You'll pick up Sudoku techniques as you play. 3 free hints every day.
In column 2, A fits only in this cell. Every other empty cell in the column already sees an A.
