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.
• Each of the 5 players start with a capital on a fixed tile. Red, 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 a match, which means to put up more entry fee to get more keys of their color.
• 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.
• The main production resources in Duper are gold (fungible) and cards (non-fungible). The main diplomatic resource is keys (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 an end condition, the match ends and the prize vault changes to that player's color. The prize is then divided as payouts to the players based on ownership of keys of the vault's color.
