How to Play Diamond Trust of London
Quick start
Start a game against the AI and read the round's available funds. Assign money and destinations to the agents, then compare a diamond purchase with keeping cash for information or wages. Review the revealed moves before committing the next plan; a paid informant can change what you know about the opponent.
Controls
Use the DS touch interface to select an agent, destination and cash allocation. Read the amount before confirming a bid, payment or move. Review available information and the round summary before advancing; the controls commit hidden plans rather than steering agents continuously in real time.
Diamond Trust of London — About this game
Diamond Trust of London is a turn-based contest of money and incomplete information. Agents travel to diamond regions, but cash also pays for loyalty and knowledge about the opposition. Spend everything on a purchase and you may have less flexibility when a bribe or an unexpected move changes the picture. Begin against the AI, learn each allocation panel and review the round's revealed actions before planning again. An agent's information is useful only if you understand which parts of the opponent's plan it exposes. Balance what you can secure now with what you need for later rounds. The DS interface supports deliberate hidden decisions rather than an action chase or a real financial transaction.
