Not enough information. – Logic Puzzles Review

Unfortunately I haven't been able to complete one puzzle out of the first four I tried without looking at the solution. It doesn't feel like there is enough information to solve the puzzles. I have another Logic puzzle app on my phone that I have no problems with. Solved one without hints... It might be a good idea to try rating them. Easy, hard, imposable.
