Armageddon is a chess tiebreaker designed to guarantee a winner. The trick is an unfair bargain: White gets more time on the clock, but Black wins the match if the game is drawn — so Black has what’s called “draw odds.” One player must win outright; a draw can’t exist as a result.
It’s the sudden-death shootout of chess. When a match or playoff is still tied after the regular games and all the faster tiebreaks, Armageddon settles it once and for all.
How the rules work
A typical Armageddon game runs something like this:
| White | Black | |
|---|---|---|
| Clock | More time (e.g. 5 minutes) | Less time (e.g. 4 minutes) |
| What a win needs | Must win the game | A draw is enough |
| The trade-off | More time, but must play for a win | Less time, but only needs to hold |
Because Black wins on a draw, White is forced to press for a decisive result, while Black can play solidly and try to hold. Often the players bid for the black pieces: each secretly writes the lowest clock time they’d accept to play Black, and whoever bids lower gets Black (and the draw odds) with that reduced clock. An increment is sometimes added, sometimes not, depending on the event’s rules.
You’ll see Armageddon at elite events — it decided games at Norway Chess and various World Championship-cycle playoffs — precisely because it produces a clean winner and a lot of drama.

Mini-FAQ
Why does Black win on a draw? To balance the extra time White gets. The whole point is to force a decisive outcome: White pays for more time by needing an actual win, and Black pays for the safety of draw odds with a shorter clock.
How is the color decided? Often by a bidding auction — each player names the shortest clock they’d accept to take Black, and the lower bid wins the black pieces at that time. Some events simply assign colors by lot instead.
