Not what I said or meant at all. I’m arguing about the proper use of the “intelligence” noun here. Does this really show a “capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. ”(Wikipedia)? I don’t think so. All I see here is a simple list of steps that a machine keeps on repeating.
We have used "AI" to denote the computer player in games for as long as I've been alive, and I'm pushing my late 30s. This is not new ground, and I'm a bit surprised you're choosing this hill to make your stand.

There is the intelligence required to play the game and the intelligence required to learn it. As long as the activity of playing Tetris can be labeled as relying on intelligence then the machine can be labeled as an excised expression of said intelligence.
