JEV Tetris

A Tetris the model plays by reading. Every possible landing is described in a sentence, Jev picks one, and the board glows with the probabilities before the piece drops.

What it does

Blocks stay dimmed by the confidence when they were placed, so the stack doubles as a record of the model's uncertainty. Spend is capped at 1,500 calls or a dollar.
