I'm sorry, i still dont get it! Do you use the codes you enter as a solution to the previous puzzles, or the answers you get after you enter the right codes?
Orange, Raven, Fear
The way i read your tip is:
A = 2 and 1 --> second letter from Orange = R B = 3 and 2 --> third letter from Raven = V C = 2 and 4 --> second letter from Fear = E Using the second number for the order makes RVE or VRE. Is there a possibility that this 'sudoku' has 2 possible answers? or do you mean something different with first and second? Is it an english wordt we're looking for?
