mug's game

Fool's hopeless endeavor

A mug's game is an activity that's foolish to pursue because it's unlikely to succeed or profit anyone but a fool.

Mug here means a gullible person, an easy mark.

The phrase is British in origin but widely understood: Trying to time the stock market is a mug's game.

Gambling is a mug's game—the house always wins.
