 This game was created by Sam Nainani in the 80's.
Prithipal Singh (28 January 1932 – 20 May 1983) was an Indian field hockey player nicknamed the "“King of short corner”" by hockey commentators.
 He participated in the Olympic field hockey three times and each time he scored the highest number of goals as a single player.
 Singh was a player with sharp reflexes, and the tremendous strength in his long and powerful arms produced firmest and sticking shots which unfailingly fetched him goals and often the winners.
 The Evening Post, New Zealand commented in 1961 that to face the fury of Prithipal's hit is to risk one's life.
 Another author commented that if Arjuna was the "Maharathi" of the Mahabharata war, Prithipal was the "Maharathi" of the International Hockey game.
 The first-ever Arjuna Award to a hockey player was conferred upon him in 1961, which was later followed by the Padma Shri in 1967.
 Singh won Olympic medals in Rome (1960 silver), Tokyo (1964 gold) and Mexico (1968 bronze).
A Game client is a network client that connects an individual user to the main game server, used mainly in multiplayer video games.
 It collects data such as score, player status, position and movement from a single player and send it to the game server, which allows the server to collect each individual's data and show every player in game, whether it is an arena game on a smaller scale or a massive game with thousands of players on the same map.
 Even though the game server displays each player's information for every player in a game, players still have their own unique perspective from the information collected by the game client, so that every player's perspective of the game is different, even though the world for every player is the same.
 The game client also allows the information sharing among users.
 An example would be item exchange in many MMORPG games where a player exchange an item he/she doesn't want for an item he/she wants, the game clients interconnect with each other and allows the sharing of information, in this exchanging items.
 Since many games requires a centralized space for players to gather and a way for users to exchange their information, many game clients are a hybrid of client-server and peer-to-peer application structures.
Man-to-man defense is a type of defensive tactic used in team sports such as American football, association football, basketball, and netball, in which each player is assigned to defend and follow the movements of a single player on offense.
 Often, a player guards his counterpart (e.g. center guarding center), but a player may be assigned to guard a different position.
 However, the strategy is not rigid, and a player might switch assignment if needed, or leave his own assignment for a moment to double team an offensive player.
 The term is commonly used even in women's basketball, though the gender-neutral 'player-to-player' also has some usage.
The Baker format in Ten-pin bowling is the cornerstone of team play because each player contributes frames to a single game.
 A single player on a 5-person team would bowl frames 1 & 6, 2 & 7, etc.
 To bowl a perfect Baker 300, all 5 players have to throw two strikes each and the final bowler, or "anchor", having to throw the two fill frames in the 10th for a total of four.
 Only a handful of Baker 300 games have been shot which is made more difficult as games in NCAA bowling are played on sport compliant patterns.
