I didn't try it myself as I'm a beginner and need to see the board, but it reportedly plays pretty well and is able to recognize illegal moves[1].

It means that it understands how physics work (e.g. things fall due to gravity). For example, it will correctly answer this question: "I put an egg inside a cup. I go to the bedroom, put the cup on the bed and turn it upside down. I lift the cup and bring it to the kitchen. Where is the egg?".
