You can't have an unsolvable puzzle! It has to follow deductive reasoning otherwise it isn't a logic puzzle. Why would you even create a puzzle that wasn't able to be solved? If you just want to create pretty pictures you need to develop a different app - this isn't an art gallery - it's a logic puzzle app based on the ability of puzzlers being able to solve a puzzle without any guesswork. Being solvable is the basic premise of Falcross. Or are you just trolling to be funny? Your question boggles the mind and I'm trying hard not to wonder how you are solving puzzles... Thank goodness this app makes them solvable...
