Leap Frog is a multi-player abstract strategy board game.
 Several players can play at once which makes it great for parties and family get-togethers.
 The game is an old classic, and may have derived from Solitaire and draughts.
 It is essentially a multi-player version of Solitaire.
 The game was described by the game historian H. J. R. Murray in his book published in 1898, along with a variant that he invented using different colored pieces each with different point values.
 Both the older variant and Murray's variant use a square board with 15 to 18 squares on each side.
 All the pieces are laid out in the beginning of the game covering the whole board.
 On each player's turn, a piece is chosen to hop over and capture other pieces on the board.
 The winner is the one who captures the most pieces (in the older variant) or obtains the most points (in Murray's variant) when it's impossible to capture anymore.
 The older variant was played in England where it may have originated from.
 The game is also known to be spelled as one word, Leapfrog.
Francis Tresham is a United Kingdom-based board game designer who has been producing board games since the early 1970s.
 Tresham founded and ran games company Hartland Trefoil (founded 1971), a company well known for its "Civilization" board game, until its sale to MicroProse in 1997.
 His "1829" game was the first of the "18xx" board game series and some of his board games have inspired Sid Meier computer games such as "Railroad Tycoon".
An Island in the Soup is a children's book written and illustrated by French-Canadian author Mireille Levert, intended for children ages 3–5.
 It was first published on May 1, 2001 by Douglas & McIntyre/Groundwood Books.
 "An Island in the Soup" is an intriguing tale that provides a fun and imaginative twist on children playing with and in their food and tells a story of fantasy and imagination incorporating both mother and child through a grand dinner time adventure.
 Mireille Levert won the Governor General's Literary Award for English Illustration for "An Island in the Soup" in 2001.
 It is "a wonderful book [...] full of illustrations that delight and stimulate.
 What sets it apart is the clever and creative journey, which appeals to children of all ages."
Sidney Walter Fox (24 March 1912 – 10 August 1998) was a Los Angeles-born biochemist responsible for discoveries on the origins of life.
 Fox explored the synthesis of amino acids from inorganic molecules, the synthesis of proteinous amino acids and amino acid polymers called "proteinoids" from inorganic molecules and thermal energy, and created what he thought was the world's first protocell out of proteinoids and water.
 He called these globules "microspheres".
 Fox believed in the process of abiogenesis where life spontaneously organized itself from the colloquially known "primordial soup;" poolings of various simple organic molecules that existed during the time before life on Earth.
 He also suggested that his experiments possessed conditions that were similar to those of primordial Earth.
 In his experiments, he demonstrated that it is possible to create protein-like structures from inorganic molecules and thermal energy.
 Dr. Fox went on to create microspheres that he said closely resembled bacterial cells and concluded that they could be similar to the earliest forms of life or protocells.
Poleconomy is a board game invented by New Zealander Bruce E. Hatherley and first published in 1980.
 It is similar to "Monopoly" but the board is divided into companies rather than properties.
 Players compete to acquire properties and investments through stylized economic and political activity.
 The playing time is set by agreement from all players, e.g. 2 hours, and the winner is determined by the monetary sum of all player cash, companies, insurance or other assets.
 The game can also end when there are no more companies, advertisements in the bank or bonds in the treasury.
 Another objective of the game is "to teach players some of the fundamentals of economics, and the ways in which the economy and the government interact."
 Different editions were published for several different countries.
 The name "Poleconomy" is a portmanteau of "politics" and "economy".
Awithlaknannai Mosona is a two-player strategy board game from the Zuni Native American Indian tribe of New Mexico, United States.
 It is unknown how old the game is.
 The game was described by Stewart Culin in his book "Games of the North American Indians Volume 2: Games of Skill" (1907).
 In this book, it was named Awithlaknan Mosona.
 Awithlaknannai Mosona resembles another Zuni board game called Kolowis Awithlaknannai (Fighting Serpents) with few minor differences.
 The former having a smaller board, and depending upon the variant, it also has less lines joining the intersection points.
 The rules are the same.
 Awithlaknannai Mosona belongs to the draughts and Alquerque family of games as pieces hop over one another when capturing.
 It is actually more related to Alquerque, since the board is made up of intersection points and lines connecting them.
 It is thought that the Spanish had brought Alquerque to the American Southwest, and Awithlaknannai Mosona may have been an evolution from Alquerque.
 However, in Stewart Culin's 1907 book, the Zunis claim that they had adopted a hunt game from Mexico similar to Catch the Hare and the Fox games of Europe, and transformed it into Awithlaknannai Mosona.
 In these games, one player has more pieces over the other, however, the other player's piece has more powers.
 The Zuni's equalized the numbers of pieces and their powers, and also may have transformed the board making its length far exceed its width.
 Diagonal lines also replaced orthogonal lines altogether.
 However, the hunt game from Mexico may have used an Alquerque board even though the game mechanics of their new game, Awithlaknannai Mosona, were completely different.
Uncle Wiggily Game is a track board game based on a character in a series of children's books by American writer Howard Roger Garis.
 The game is of the "racing" variety in the style of the European "Goose Game".
 Players advance along the track from Uncle Wiggily's Bungalow to Dr. Possum's House.
 There is no optimal strategy involved as play entirely rests upon a random drawing of the cards.
 The game was first published by Milton Bradley in 1916 and has seen several editions with minor modifications over the years.
 "Uncle Wiggily" remains one of the first and favorite games of childhood, and, with "Candy Land", is considered a classic juvenile American board game.
Primordial Soup is a board game designed by Doris Matthäus & Frank Nestel and published by Z-Man Games.
 It was first published in 1997 in Germany by Doris & Frank under the name Ursuppe and this original version won 2nd prize in the 1998 Deutscher Spiele Preis.
Primordial soup, or prebiotic soup, is a hypothetical condition of the Earth's atmosphere before the emergence of life.
 It is a chemical environment in which the first biological molecules (organic compounds) were formed under natural forces.
 According to the theory, simple organic compounds were created from non-living inorganic molecules (abiogenesis) through physical and chemical reactions on the Earth's surface.
 The so formed organic molecules accumulate into a rich organic ocean, or a "soup".
 In this soup, simple organic molecules reacted with each other (polymerise) to form more complex molecules, including nucleic acids and proteins, which are the central structural and functional components of all organisms.
 These molecules then aggregate to become the first forms of life.
