simple logic grids

Recently I bought my partner a book of logic puzzles. Most of the puzzles were "Logic Grids", like these. I looked online, and there were lots of examples of logic grids. Some really nice people had great instructions pages – "how to make your own logic grid puzzles". Thanks to their advice, I could make the logic grids in this app. Instructions: Read the hints, Place "o"s and "x's on the grid.Here are some hints that might help you complete these logic grid puzzles.- Ruling out combinations is important. Once you know that 2 options have been ruled out, then you know that the remaining option must be the correct choice.- Sometimes you will get a hint that you can't use just yet. Put it to the side, and continue on. After one or two more hints, it will become clear how you can use the earlier hint.- Look at each hint and check whether you have used it fully.
