Viking Dominion

Rules

In addition to obvious mechanics you can deduce from the gameplay, keep these special rules in mind:

1. Time limit: Every player has a limited amount of time to perform their moves. If you don't act before your timer expires, you lose the game.
2. Ragnarok: The game owner can invoke Ragnarok at any moment, which immediately ends the game. No winner is declared – only the best-scoring player is recorded.
3. Quitting: You can quit at any time. If the owner quits, ownership passes to another human player. If no human players remain, the game ends.
4. CPU hostility: Attacking a CPU player gives you a bad reputation with that player, and it will be more hostile towards you for the next three rounds. This is in addition to the baseline hostility set by the game owner.
5. CPU autonomy: The CPU can do everything a human player can do, including attacking you, proposing alliances, and breaking alliances. The difficulty level adjusts how efficiently they harvest their resources, and the hostility level indicates the probability they attack other players or enter/break alliances.
6. Alliances: Regions controlled by your allies count towards your total when pursuing Viking Dominion. And - allies cannot attack each other!
7. Alliance proposals: If you propose an alliance you cannot attack that player the same round. If a player proposes an alliance to you, you must refuse it before attacking them during that round.
8. Breaking alliances: The side that breaks an alliance cannot attack during that round. The opponent can! Breaking an alliance with a CPU reduces the likelihood that the CPU will ally with you ever again.
9. Victory condition: Victory is determined at the end of each turn. A player or alliance that achieves Viking Dominion at that point wins the game.
