The Arena

One field, two slots. You step on with a boast and wait — that part is free, and so is walking back off. Whoever answers starts the fight: 100 years burn from each side that instant, and for the next 24 hours the two of you are the headline of the board.

Then the visitors decide it. Every vote is a click, and every click burns another year off the side it was cast for — so winning costs more than losing. Nobody is paid. The winner gets a card down there that never comes off the page. 0 immortals remain.
