Terminology
- Duper has two principal components, which we shall refer to as the map and the chat.
- A tile is the main spatial unit of Duper. The map has 37 tiles in total. A tile may be owned by a player. Two tiles are adjacent if they share an edge.
- Each of the 5 players start with a capital on a fixed tile. The middle player is always the player who has the earliest turn order, and is referred to as the dealer.
- There are opportunities for players to raise during the session.
- A round is the main temporal unit of Duper. Within each round, players have their turns in sequence starting from the dealer. A player may attack only during their own turn, but may perform any other action (e.g. trading, production, movement) outside of their turn.
- Tiles may host units, the umbrella term for troops and buildings. At any given time, each tile can host at most 1 class of air troop, 1 class of ground troop, and 1 building.
- Research centers train talents which unlock special abilities.
- The main production resources in Duper are gold (fungible) and cards (non-fungible). The main diplomatic resource is gems (semi-fungible).
- Card combos used in production may later trigger combo rewards.
- For each player, the chat is composed of 4 private channels with the other 4 players. Resources flow between players through trades that get proposed and accepted in those channels.
- When a player meets a victory condition, the session ends and the pot is divided as payouts to the players based on gem ownership of the winner's.
