Moundball is a side-betting game typically played by spectators at Major League Baseball games.
 Often played to pass the time during slow games, Moundball has a simple ruleset and requires little to no equipment.
 The game is turn-based, with the goal of having the ball remain on the mound at the end of a player's half inning turn.
 The game was invented and patented by Frank Bonelli from the Kings Park, New York during the summer of 1977.
 Frank also invented the classic cocktail "The Frankie B" consisting of Stoli O, soda, splash of orange, splash of cranberry.
 He is now retired and he travels around the country teaching fans the basic rules of the game.
Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus.
 Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain.
 One player must win; there are no draws.
 The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem.
 It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash.
 The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production.
 Hex can also be played with paper and pencil on hexagonally ruled graph paper.
Two popular American sports were invented in New England.

The Shannon switching game is an abstract strategy game for two players, invented by American mathematician and electrical engineer Claude Shannon, the "father of information theory" some time before 1951.
 Two players take turns coloring the edges of an arbitrary graph.
 One player has the goal of connecting two distinguished vertices by a path of edges of their color.
 The other player aims to prevent this by using their color instead (or, equivalently, by erasing edges).
 The game is commonly played on a rectangular grid; this special case of the game was independently invented by American mathematician David Gale in the late 1950s and is known as Gale or Bridg-It.
Blockhead is the name of a theoretical computer system invented as part of a thought experiment by philosopher Ned Block, which appeared in a paper titled "Psychologism and Behaviorism" (though Block does not name the computer in the paper).
Cups was one of several games invented in 1965 by father and son Arthur Amberstone and Wald Amberstone who were both cofounders of the New York Gamers Association (N.Y.G.A.).
 They also invented Power, and High Deck, a card game based on medieval society.
 At the time both were working as basket makers as well as game designers in New York City.
 This game was first published in A Gamut of Games by Sid Sackson in 1969.
 Wald Amberstone co-founded the Tarot School in 1995 along with his wife Ruth Amberstone.
 The game Cups is a contemporary two-ranked single-lap member of the ancient game family of Mancala.
Stratego is a strategy board game for two players on a board of 10×10 squares.
 Each player controls 40 pieces representing individual officer ranks in an army.
 The pieces have Napoleonic insignia.
 The objective of the game is to find and capture the opponent's "Flag", or to capture so many enemy pieces that the opponent cannot make any further moves.
 "Stratego" has simple enough rules for young children to play, but a depth of strategy that is also appealing to adults.
 The game is a slightly modified copy of an early 20th century French game named "L'Attaque".
 It has been in production in Europe since World War II and the United States since 1961.
 There are now 2- and 4-handed versions, versions with 10, 30 or 40 pieces per player, and boards with smaller sizes (number of spaces).
 There are also variant pieces and different rulesets.
Blockhead!
 is a game invented in 1952 by G.W. "Jerry" D'Arcey and developed by G.W. and Alice D'Arcey in San Jose, California.
 Originally consisting of 20 brightly colored wooden blocks of varying shapes, the object of the game is to add blocks to a tower without having it collapse on your turn.
Stratego: Legends is a strategy board game created and released by Avalon Hill in 1999, with rules similar to "Stratego".
 Set in a mythical world called "The Shattered Lands", it pits the forces of good (represented by beige-back pieces) against the forces of evil (represented by gray-back pieces).
 It plays similar to the original "Stratego" game, and also somewhat similar to chess.
 The game was discontinued by Avalon Hill in 2004.
Luzhanqi () (lit.
 “Land Battle Chess”) is a two-player Chinese board game .
 There is also a version for four players.
 It bears many similarities to Dou Shou Qi, Game of the Generals and the Western board game Stratego.
 It is a non-perfect abstract strategy game of partial information, since each player has only limited knowledge concerning the disposition of the opposing pieces.
 Because of the Chinese nature of the game, terms used within the game may vary in translation.
