Survive: Escape from Atlantis!

Setup and goal: The base rules support 2–4 players. Place the Terrain tiles face up at random on the sea spaces to form the island and put Sea Serpents on the marked spaces. Each player takes ten Explorers and two starting Ships. Secretly inspect the 1–6 value on the underside of each Explorer and remember it, then take turns placing all ten on empty island tiles and placing both Ships on free sea spaces next to the island. At the end, the player with the highest total value on rescued Explorers wins.

Turn order: Players take turns clockwise from the First Player. A turn has up to four steps in order: optionally play one Terrain tile from hand that was gained earlier, move Explorers and/or Ships for a total of three spaces, remove one eligible Terrain tile and secretly check its effect, then roll the Creature die and move the indicated sea creature. Skip the hand step on the first turn or when you have no tile. Resolve the remaining steps in their printed order.

Movement and rescue: Your three movement spaces can be split among different Explorers and Ships. An Explorer on land may move to an adjacent Terrain tile, board a Ship on an adjacent sea space, or transfer between adjacent Ships. A Ship holds up to three Explorers, and a person who has left the island cannot return to land. A Swimmer moves only one sea space per turn and cannot cross a space occupied by a Shark or Sea Serpent. From a sea space next to a safe isle, an Explorer may spend one movement to land; any of the safe isles can be used.

Removing Terrain: Each turn you must remove a Terrain tile adjacent to at least one sea space. Remove all Beach tiles before Forest tiles, then remove Mountain tiles; the rulebook has a surrounded-tile exception for the last tile of a height. Explorers on a removed tile fall into the sea space it occupied. Secretly inspect the back and follow its timing: some effects happen immediately, some are kept for the start of your turn, and some are defensive tiles played during another player's creature movement.

Ships and creatures: Any player can move an empty Ship. A Ship carrying Explorers is controlled by the player with the most people aboard; if tied, each tied player controls it. The Sea Serpent die face moves one space, the Shark moves one or two spaces and removes Swimmers where it stops, and the Whale moves one to three spaces and capsizes an occupied Ship, sending its passengers into the sea. A Sea Serpent can also destroy a Ship with passengers and any Swimmers in its space. Creatures do not attack one another and can share a sea space.

Terrain tile effects: A tile's back may add a Ship, Shark, or Whale to the sea space that the tile occupied, move an existing creature, or create a Whirlpool that removes units from the space and adjacent sea spaces. Other tiles provide movement, and some remain in hand for later use or defense. Not all tiles resolve at the same time: reveal the effect and follow its outline and icon to determine whether it is immediate, a start-of-turn effect, or a reaction to another player's move.

Volcanic end: A Volcanic Eruption symbol is hidden under a Mountain tile. When that tile is removed and revealed, the eruption destroys the remaining island and the game ends immediately. Explorers who have not reached safe isles are no longer eligible to score. If a player has no Explorers left to move before the volcano is revealed, the game continues; that player skips the movement step but still follows the other turn rules.

Scoring and winner: After the eruption, each player turns over the Explorers they successfully brought to safe isles and adds their hidden values. Explorers still on the island, in a Ship, or swimming do not score; figures removed by creatures or a Whirlpool also score nothing. The target is total treasure value, not the number of rescued figures, so saving a smaller group of high-value Explorers can beat a player who rescued more people with lower values.
