How to play Dice World War
Every country on Earth, one dice roll at a time.
Dice World War is a free browser game that turns the world map into a board game. Around 240 countries and territories start the game as independent nations. Each time you press Clash, one of them attacks a neighbour, both sides roll three dice, and the winner takes over the loser's land and people. Battle after battle, empires grow until a single nation rules the whole world. Every game ends differently: Luxembourg can build an empire, and a Pacific island can bring down a giant.
One battle, step by step
- An attacker is chosen. A marker walks across the map and stops on a random nation that is still standing. Every surviving nation has the same chance to attack, however big or small it is.
- A defender is chosen. Dotted lines connect the attacker to every rival it can reach. Land neighbours come first. Islands and countries that have run out of land neighbours reach across the sea to their nearest rivals. The marker circles the attacker's borders and stops on the defender.
- Both sides roll three dice. The dice are then matched in pairs: first against first, second against second, third against third.
- Each pair is a mini-duel. The higher die scores the difference as points. If the attacker rolls a 6 and the defender a 2, the attacker scores 4 points. A tie scores nothing for either side.
- Points are multiplied by power. Each side's total is its points × its population power. The higher total wins. If the totals are exactly equal, both sides roll again.
- The winner takes everything. The loser's whole empire, with all its land and people, joins the winner, and the winner's flag stretches over all its territory. This happens even when the defender wins: a failed attack can cost the attacker its own empire.
Population power
Bigger populations fight harder, but not overwhelmingly. You can choose how much population matters in the Rules tab of the Leaderboard:
- Balanced (default): power = 1 + 0.1 × √(people ÷ 10 million). Big countries have an edge, but each extra million counts for less, so a small island still beats China roughly one time in three.
- Classic: power = 1 + 0.1 per 10 million people. Giants are very hard to beat.
- Dice only: power is always 1, so population doesn't matter. Pure luck.
Power uses the whole empire's population, so it grows with every conquest.
Following the war
- Tap any country on the map to see its population, area, power and who rules it.
- Leaderboard shows the largest empires by territory and by population, a full history of every battle with the dice that were rolled, and the rules.
- Your world is saved on your device, so you can close the game and continue the same war later. Press New world to start over with every nation independent again.
Where the data comes from
Country shapes come from Natural Earth, a public-domain world map. Populations come from the World Bank's latest figures. A few small territories that the World Bank doesn't list use our own approximate estimates. Borders and names are game data, not political statements. See credits & licences for every source.
