Welcome to Sudokache, the first Sudoku-Cache in Portugal! As you may have guessed by now, in order to find the cache you will first have to solve the game! After that, just use the hints below to get your final coordinate, after which you can proceed with the hunt!
This is what you have to solve:
In case you've never heard of SuDoku, it is a logic puzzle (like crosswords) and there is only one solution. The goal is to insert the numbers in the boxes to satisfy only one condition: each row, column and 3x3 box must contain the digits 1 through 9 exactly once. What could be simpler?
When you get your Sudoku solved, use this grid to find the final coordinate. Good luck!!!
