What was a regular day turned into a nightmare for a young woman who awakes locked in the back of a truck not knowing what happened, who she is, or what will happen next.
What's worse is you are that woman, and it's up to you to crack puzzles, codes and escape traps laid out by this serial killer.
Problem is, he is watching you all along and what seems like the exit might lead to another trap!
The aim of Sudoku Companion is to make solving Sudoku puzzles more convenient.
