ON SPEC is a round game based on the buying and selling of stocks and shares. Cards consist of "share cards" and "quotation cards". Share cards come in the commodities of Rails, Rubbers, Oils, Gold, Motors and Shipping and are beautifully printed coloured chromo-lithographs. Quotation cards are less spectacular and show numbers in red and black for "up" and "down". Following the game rules you can speculate in rise and fall, trying to find the best moment to buy or sell. Stock price is adjusted by central play of the cards of the stockbroker player. Play money are little coloured bone chips. Nice little time-witness game with outstanding components quality.
