Stone Age

The original base game supports 2–4 players. Each starts with five people, twelve food, zero agriculture and zero points. Prepare one seven-tile building stack per player.

Each round proceeds through placement, action resolution and feeding. In clockwise placement turns, commit the required people to one location. You cannot add people to a location where you already have people that round.

The tool maker and field each hold one person; the hut requires two of one color placed together. Each resource site holds seven people, hunting has no capacity limit, and each displayed civilization card or building holds one.

After placement, the first player resolves all their locations before the next player does so. Resolve your locations in any order and return the people after their actions.

Roll one die per person gathering. Add any tools used, then divide by two for food, three for wood, four for clay, five for stone or six for gold, rounding down. Each tool tile can be used in full only once per round.

The field raises agriculture by one. The hut adds a person for placement in future rounds. Buy civilization cards with the resources required by their position; food cannot pay for cards or buildings. Buildings award points immediately after their required payment.

For feeding, collect food equal to agriculture, then pay one food per person. Spend all available food first; resources may cover the shortfall one for one. An unpaid shortfall costs ten points, regardless of how many people remain unfed.

Pass first player clockwise. Before the next round, slide remaining civilization cards right, refill to four and reset tools. If cards cannot refill, end before that new round. If a building stack empties, finish the current round, including feeding, before ending.

Add civilization scoring: each set of different green cultural symbols scores its size squared, with duplicates forming further sets. Sand-background figures multiply agriculture, total tool value, buildings or people as appropriate. Each leftover non-food resource scores one; highest total wins.

With two or three players, use only two of the tool maker, hut and field each round. Resource sites may hold at most two players in a three-player game and one in a two-player game. Break a score tie by the combined agriculture level, total tool value and number of people.
