[1774]
Similarly to how I solved the annoying puzzles in Onimusha 2 puzzle boxes, I did a quick brute force on the Castlevania rotation puzzle, using the hint that only one-way rotation should be needed:
# Castlevania: Lords of Shadow: Pan's Temple puzzle solver by schmid 2012-05-24
moves = [ [-1,+1,-1,"middle RT"], [+1,-1,0,"inner RT"], [0,-1,+1,"outer RT"] ]
def apply(move, puzzle)
(0..2).each do |n| puzzle[n] = (puzzle[n] + move[n]) % 4 end
end
random = Random.new
100000.times do
puzzle = [1,1,1] # start position (0 is north, 1 is east, etc.)
move_list = []
(1..5).each do |m| # shortest solution is 5 moves
move = moves[ random.rand(0...moves.length) ]
apply(move, puzzle) ; move_list += [ move ]
if puzzle == [2,2,2] then # solution is all south
puts "solution:" ; move_list.each { |move| puts move[3] }
exit
end
end
end
Solution: outer RT x 2, middle RT, inner RT x 2
