Item seen rolling through this puzzle

DIE

A small cube with dots might decide your fate in a board game.

This clue plays on the double meaning of "die"—it can refer to a small cube used in games (like in board games) or the verb meaning to stop living. The word "rolling" hints at the action of a die being tossed, while "through this puzzle" suggests it’s something you’d find in a crossword. The pun works because a die is literally an "item" that rolls, making the answer a clever twist on the phrase.
