Players build an economic empire across the Indonesian archipelago across three eras. Players start production companies (rice, spice, rubber, siap faji, oil) and shipping companies, operate them to sell goods to growing cities, and compete through mergers and acquisitions. Shipping companies transport goods from production areas to cities, earning fees. Production companies sell goods at fixed prices but must pay shipping costs. Cities grow when they receive all available types of goods. The game spans 3 eras with increasingly valuable goods becoming available. The player with the most money (including banked bid money) at the end wins.
The game plays across 3 eras. Each era consists of multiple years. Each year has 7 phases:
A new era starts if no companies from the previous era remain to acquire, or only one type remains. When an era starts:
In current play order, each player bids cash once (0 is allowed). Bid money goes to the “Bank” box on the player aid (cannot be spent again but counts for final scoring). Highest bidder goes first. Ties preserve relative order. Players with Turn Order Bid R&D have their bid multiplied accordingly (mandatory).
Only players who have researched Mergers on the R&D track may announce mergers. Multiple rounds until no one wants to announce more. Mergers always combine exactly 2 companies of the same type.
Announcing: In turn order, a player may announce a merger. The announcing player must own one of the companies or have a free slot. The number of deeds in the resulting company is limited by the announcer’s Merger R&D level.
Bidding: Announcer bids first (minimum = nominal value: number of goods x value per good). Bids increase in multiples of total goods count. All players with a free slot or who own a merging company may bid. Passing eliminates you from that merger’s bidding.
Resolution: Winner pays the total bid, divided among former owners proportionally by goods count. Company deeds are stacked together under the new owner.
Nominal values: Rice=20, Spice=25, Rubber=30, Siap Faji=35, Oil=40, Ships=10.
Siap Faji mergers: A rice + spice company merge into siap faji (era b or c only). Nominal value = total goods x 25. After merger, new owner must give up half the goods areas (rounded up), clearing those areas. Remaining goods become siap faji. Siap faji companies can only merge with other siap faji companies afterward.
In turn order, players may start one available company per round (free, but need a free slot). Rounds continue until all players pass or no companies remain.
Each player may advance 1 step on one R&D track:
| Track | Effect |
|---|---|
| Slots | Number of companies you may own simultaneously |
| Mergers | Max deeds in a merger you announce (1=none, 2=two singles, etc.) |
| Hull | Goods each of your ships can transport per production company |
| Expansion | Max areas a company can expand per operation |
| Turn Order Bid | Multiplier for your bid in Phase 2 |
You may advance another player’s Hull track instead of your own (useful if they own a shipping company transporting your goods). No other tracks may be advanced for other players.
Players operate companies one at a time in turn order, multiple rounds, until all companies have operated once.
Shipping companies: May expand (place new ships in or adjacent to existing ship areas, up to the deed’s era limit, constrained by Expansion R&D).
Production companies (three steps in order):
Take an available company deed from the current era (free). Place initial goods/ships according to company type.
Expand: Place new ships in or adjacent to existing ship areas, up to the deed’s era limit. Number of ships added per turn limited by Expansion R&D.
Announce a merger of 2 same-type companies. Bid at least nominal value. Winner pays proportionally to former owners. Resulting merged company occupies one slot.
Advance 1 step on one of 5 R&D tracks: Slots, Mergers, Hull, Expansion, or Turn Order Bid.
Cities that received every type of good currently produced on the board (up to their capacity) grow one size. Size 1 needs 1 of each type; size 2 needs 2 of each. Discard all delivered goods. If insufficient upgrade tokens, first player in order of play chooses which cities upgrade.
The game ends in Phase 1 when era “c” ends (all c-era companies acquired, or only one type remains).
Final operations phase: All money earned in the last operations phase is doubled. Keep it separate, then double and add to cash at game end.
Winner: Player with the most total money (cash + banked bid money) wins. Tiebreaker: first in order of play.
