Players will challenge themselves and their friends in testing their logic and memory skills while trying to place in order either length or weight of dinosaurs. Both sides of each card depict a dinosaur, its name, its geographic place, while its average length and weight are printed on the other side. For each game, players decide before playing whether they're comparing dinosaur lengths or weights. Place your card in the right spot on the “timeline,” and it stays – wrong spot and it goes. The first player to get rid of all their cards by placing them correctly wins. All of these cards are compatible with the cards from the Cardline Animal series. This way, by using various boxes with different themes, you increase the possibilities and the fun of playing. For 2-8 players. From Asmodee, for ages 7 years and up. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3yrs.
