The droids puzzle was actually one of the more brain using puzzles in the game. You could skip it by simply hacking the droids if you had the amount of spikes needed, but, if you don't mind using your noggin' and have no problem with logic puzzles, you could save the spikes all together. I think that was my favorite puzzle in the game. The only problem I had with it, was once you knew the answers, that was it. Would have been nice if they had changed it from game to game. Wouldn't have been too hard, actually.
