Dominion Tournament Rules: The Hour, the Kingdom, and the Bid

The rules of Dominion do not change at a tournament. The procedures around them do. This lesson uses the World Boardgaming Championships event, because it is the best-documented face-to-face Dominion tournament, and its 2026 event preview spells the procedures out. Other events, and later years, may differ, so always read the current rules for your event.

The structure

• Three heats, each one hour. Win any heat and you advance. Play more than one heat if you want more chances.
• A quarterfinal of up to 64 players, then a semifinal of 16, then a final of 4.
• Class B: the event welcomes beginning players.
• Bring a copy of the game. The preview notes that players have been turned away from heats in past years for lack of copies.

The card pool and the kingdom

Heats through the semifinal use the base game, Intrigue, Seaside, and Prosperity, in first or second edition, with Prosperity’s Colony and Platinum left out. Each table picks ten Kingdom cards at random, with the randomizer cards or a free randomizer app.

The final is different. The game master chooses its ten cards ahead of time, may include expansion cards not normally allowed, and may add special rules. Nobody sees the kingdom or the rules until the final sits down.

That means two kinds of preparation. For the heats, learn the four allowed sets well enough to read any kingdom from them in two minutes. For the final, the skill is reading unfamiliar cards fast, which is why the expansions lesson is worth revisiting at this level.

Bidding for your seat

In the semifinal and final, turn order is bid for. Following the preview: in a random sequence, players bid in half-point steps for the seat they want. If someone outbids you, you may bid again on your turn. When every seat has a bid, the bids are final, and each player’s bid is taken off their score at the end of the game.

How much is a seat worth? There is no fixed answer, and it depends on the kingdom. Some thoughts to bid with:

• Going first is an edge. In a simple simulation of two identical money decks at two players, the first player wins about 52% of games against about 41% for the second. Edges in other kingdoms and at more players will differ.
• Late seats have their own edge. In rounds after the heats, a tie that survives the turn count goes to the later seat.
• Every half point is real. A 1-point bid means you have to finish more than 1 point ahead to win. Close Dominion games are often decided by a Duchy or an Estate.
• Read the kingdom first. A kingdom with a strong attack like Witch may reward getting it into play first.

Ending and ties

The preview says buying out the Provinces or any three other Supply piles ends the game immediately. The rulebook ends the game at the end of that turn, so ask the GM which applies before you rely on a last-turn trick. Most points wins, after bids. Ties go to the player with fewer turns. If still tied, both players win in a heat; in the quarterfinal and later, the player with the later starting seat wins.

Playing well against the hour

An hour is plenty for most Dominion games, but random kingdoms, setup, and longer engine turns can eat it. Habits that save time:

• Plan during setup. Read the kingdom while the piles go out, using the two-minute routine.
• Think on other turns. Decide what you will buy at each price before your turn arrives.
• Shuffle well and quickly. Know your shuffle; a fumbled shuffle costs seconds every turn.
• Count Actions out loud on engine turns, as the rulebook suggests. It prevents arguments.
• Keep your play area tidy, so others can see what you played without asking.

Etiquette

Name your buys. Keep your discard pile neat with the top card visible. Do not count anyone’s discard pile, including your own. Let others finish resolving an attack before you play on. Shake hands. These are small things, and they make tournaments the kind of room people come back to.
