Overview

Jurassic Snack is a two-player game where teams of young Diplodocuses (Diplos) compete to eat the most tasty leaves from neighboring pastures. Players move their Diplos to eat Grass tokens and can deploy T.Rex dinosaurs to scare away opponent Diplos. The player who eats the most valuable grass wins – unless a T.Rex eliminates all of an opponent’s Diplos first.

Components

Setup

  1. Connect the four Pasture boards in any arrangement where each board shares at least one full side with another board (recommended: a square for first game).
  2. Each player takes 5 Diplos in their color. Place 4 on the egg spaces matching their color on the boards; the 5th goes in the player’s pool.
  3. Both T.Rex are placed in a pool on the edge of the playing area.
  4. Shuffle 28 Grass tokens face-down and place them randomly on the 28 board spaces without looking.

Turn Structure

Actions

Moving a Diplo (Herbivore)

A Diplo moves in a straight line until blocked by:

  1. Another Diplo
  2. A T.Rex
  3. The edge of the playing area
  4. A Grass token – the Diplo eats the grass, replacing the token on that space. The token is revealed, its effect is resolved immediately, then placed face-down in front of the player.

Moving a T.Rex (Carnivore)

A T.Rex moves in a straight line until blocked by:

  1. Another T.Rex
  2. A Grass token
  3. The edge of the playing area
  4. A Diplo – the T.Rex scares the Diplo away: the T.Rex replaces the Diplo on that space, and the Diplo returns to its owner’s pool.

Scoring / Victory Conditions

The game ends immediately when any of these conditions is met:

  1. A player has no Diplo left on the board – that player LOSES regardless of grass scores.
  2. No Grass tokens remain on the board – each player reveals their collected Grass tokens and the highest score wins.
  3. Stalemate – during two consecutive turns, NO player has eaten a Grass token or scared away an opponent’s Diplo. Highest score wins.

In case of a tie, the player with fewer Grass tokens wins. If still tied, players share the victory.
