What you need

CATAN plus Seafarers, the player-count frame, the four island groups, sea hexes, number discs, ports, pirate and robber, player pieces, and the scenario VP supply.

• Players: 3 or 4.
• Required games: CATAN + Seafarers.
• Generator mode: randomized / variable board.
• 3 players: 20 land + 15 sea hexes, 20 discs, 9 active harbors, and 18 VP tokens.
• 4 players: 23 land + 12 sea hexes, 23 discs, 9 active harbors, and 24 VP tokens.

Before you generate

The generator randomizes the four published island areas while keeping the frame, sea positions, harbor edges, and port count in place.

Set up the table

1. Use Configure this setup above. It opens the 4-player variable selection by default; choose 3 players when needed, then generate.
2. Build the matching frame and place the sea hexes, then use the print setup sheet to sort the four island pools, discs, harbors, and VP supply.
3. Place the generated islands, robber on the 12, pirate, and harbor types at their shown edges; keep island and sea counts separate.
4. Each player chooses one island or two different islands for starting settlements with roads or ships, following the scenario page.

Scenario notes
