Here's my first puzzle attributed to the fortnightly topic, movies. I figured I'd try my hand at this series of pattern recognition puzzles.
Below is a chart listing words that fall into one or neither of two categories, Spiel Words™ and Spieg Words™ (though it should be noted that all Spieg Words™ are also Spiel Words™, they are just a more specific categorization). Mathematically speaking, the set of all Spieg Words is a subset of the set of all Spiel Words
Can you determine the rule I use to decide if I call it a Spiel Word™, a Spieg Word™, or neither? Feel free to ask below for certain words, but I ask that to avoid spamming up the question, if you have multiple, please ask them all at once.
