Which leads me to my question. Apart from flipping a coin (which I would argue is not a "game" per se) is there ANY GAME whose outcome is SOLELY determined by luck?


As noted, some games are 100% "luck" (or variance, or statistics, or whatever semantics people categorize it as). Casino
slots is another good example. Okay, sure, you might know the probability of winning if you knew the programming within that specific machine at that time, but from the player perspective, it is purely luck as nothing you can do can help you win more (granted, there are "tricks" and "strategies" such as which slot machines to play and for how long, but for this example I am assuming you are only playing the same machine constantly).
As far as your RockPaperScissors example with them throwing Rock 40% of the time, research "Nash equilibrium" if this is new to you. This is only one minor point of the broader field of study known as "Game Theory" in philosophy/statistics, but once Nash equilibrium is reached (point when changing strategy is no longer beneficial and your perspective is optimized), then the deviation in shortterm results (although it should balance longterm by definition of the game state) would be luck in the purest form.
At least that is how I see it.
