Mombasa is a strategy game with an economic focus set in the age of chartered companies. Players acquire shares of four companies based in Mombasa, Cape Town, Saint-Louis, and Cairo, spreading trading posts across Africa to earn money. The game combines card play, area control, and track advancement over 7 rounds. Players simultaneously select and play action cards, then resolve actions to expand companies, gain shares, advance on book and diamond tracks, and collect bonuses.
Each of 7 rounds has 3 phases:
Simultaneously, each player selects 3 action cards from their hand and places them face down on their 3 card slots (left, center, right).
Players take turns performing actions. In turn order, each player reveals and resolves one action card at a time, proceeding through multiple action rounds until all cards are resolved. Actions include:
Play expansion cards matching a company’s color to place trading posts in adjacent regions on the board. Each region’s trading post increases the value of shares for that company.
Four separate company tracks represent your shareholding. Advancing costs coins but yields higher dividends and end-game VP.
Advancing on the book track grants powerful bonuses and significant end-game VP. Players collect book tiles that provide immediate or permanent benefits.
Similar to the book track; advancing grants bonuses and end-game VP from diamond-related scoring.
Cards placed on different slots cycle at different rates. Managing which cards go where determines your strategic flexibility across rounds.
After 7 rounds, final scoring includes:
| Source | Points |
|---|---|
| Company shares | Track position x company value (number of trading posts) |
| Book track | VP based on ink jar position |
| Diamond track | VP based on diamond marker position |
| Coins | 1 VP per 5 coins |
| Bonus tiles | As printed |
The player with the most VP wins.
| Phase | Action |

| End | After 7 rounds: shares x company value + book + diamond + coins |
