Safe in Grandpa’s Room / How to Solve
You need two pieces of paper to get the combination. The first was found in the bathroom on the stand and the second is in the locked drawer in the clock room which you open with the bolt cutters.
Those two pieces of paper give you the full combination for the safe.
One piece of paper will tell you a number and direction at top with a second number below it and scratched out direction.
The second piece of paper will tell you a direction on top and a scratched out number and a number and direction below that. The two parts that are scratched out combine together to make the number AND direction for the middle digit.
So just enter the combination as if both pieces of paper were one… from top to bottom.
