Trading
Trades are how resources flow between players. They help players achieve otherwise difficult actions, such as collecting a combo, launching a 2-step attack in a turn, and building a fort.
A player may initiate a cards exchange at the start of the shared round. Each player can only perform one trade per round during the trading window. These trades are automatically accepted and cannot be rejected by the counterparty.
At any time, a player can initiate the other types of trades: swap keys, sell key, and buy attack point. Unlike the cards exchange trades, the counterparty can accept or reject the trade.
There are 5 different types of trades in Duper:
| Trade Class | Initiator gets | Recipient gets | Initiator Prerequisite | Usage Limit |
|---|---|---|---|---|
| Exchange cards | 1 chosen card | 1 provided card + 1 initiator-colored key + 1 coin | borders recipient OR has completed economy center | only during trading window beginning of round |
| Sell key | 4 coins | 1 sold key (cannot be initiator-colored) | has completed economy center | 1 per round |
| Swap keys | 1 recipient-colored key | 2 coins + 1 initiator-colored key | borders recipient OR has completed economy center | 1 per round |
| Buy attack point | 1 attack point | 1 initiator-colored key | has completed economy center | 1 per game session |
Note that whatever the initiator gets comes from the recipient, and vice versa. For example, if Player A initiates a "swap keys" trade to Player B but does not have at least 2 coins, the request will fail.
More details:
- Exchange cards: Let's say player A has 3 cards. Other players who either borders Player A's tiles or has a completed economy center would see his cards on the top of the chat. One of them, Player B, may then initiate the "exchange card" trade by clicking on her desired card and providing one of her own cards.
- Sell key: Note that the initiator may only sell a key he owns that is not his color. The "sell key" trade often creates unexpected shifts in diplomacy.
Note: A player may choose to hide some of his cards from others. Click on the cards you wish to hide and click the crossed eye button to do so. To unhide them, click on the cards you wish to unhide and click the open eye button.
