It's a daily bonus round on OWdle where you hear one Overwatch hero's melee swing and have to guess who it is. You get three tries, and the full source clip plays back once you solve it or run out.

Hit play to hear the melee sound, type in the hero you think it belongs to, and you have three guesses. Every hero sounds a little different when they swing, so listen for the weight and pitch of the hit.

Melee is a bonus mode, so it sits outside the five daily modes and doesn't count toward your streak or rank. It's just an extra round to play, with a fresh hero every day.

Yep. A new hero's melee sound goes up every day at 2:15am Pacific, the same reset as the daily OWdle puzzles, and everyone gets the same one that day.
