A screening game is a two-player principal–agent type game used in economic and game theoretical modeling.
 Principal–agent problems are situations where there are two players whose interests are not necessarily matching with each other, but where complete honesty is not optimal for one player.
 This will lead to strategies where the players exchange information based in their actions which is to some degree noisy.
 This ambiguity prevents the other player from taking advantage of the first.
 The game is closely related to signaling games, but there is a difference in how information is exchanged.
Isola is a two-player abstract strategy board game.
 It is played on a 7x7 board which is initially filled with squares, except at the starting positions of the pieces.
 Both players have one piece; it is in the middle position of the row closest to his/her side of the board.
The NBL Canada All-Star Game is an exhibition game hosted by the National Basketball League of Canada (NBL), currently matching a group of players from the Central Division against a group from the Atlantic Division.
 The first All-Star game took place at the Halifax Metro Centre in Halifax, Nova Scotia on April 1, 2012.
 In the inaugural game, the format did not take divisions into account and randomly divided players under captains Joey Haywood and Eddie Smith.
 As of 2014, the players are decided on the coaches' votes.
 No All-Star game took place for the 2014–15 NBL Canada season.
 The game takes place alongside multiple other competitions, together known as All-Star Weekend.
 These competitions include the Three-Point Long Distance Shootout and the Slam Dunk Championship.
 Neither event took place in 2015.
Matching games are games that require players to match similar elements.
Fish Tank is combination of popular Match 3 genre with arcade puzzle games.
 It’s an arcade-style matching game from iFun4all.
 However, instead of matching gems or blocks, you are matching colors of fish.
 It's kind of combining traditional match-three gameplay with reflex-based mechanics.
Gus Goes to Cybertown is a children's educational CD-ROM game released in 1993 by Modern Media Ventures.
 The main character is Gus, a talking & singing dog, who must find the three CyberBuds hiding in each of the town's five locations.
 Games are also hidden in each location, from spelling and number games to shape recognition and pattern matching games.
 Cybertown's park includes a timeline that shows Gus through time, from a Neanderthal to a futuristic spaceman.
 As the time changes, players can click on other items in the park to see them change as well.
 CyberBuds are revealed by interacting with various parts of each area.
 These characters will also provide tidbits of educational information.
Snout!
 is a variation on the classic dice game Pass the Pigs.
 Unlike the original, players earn points by discarding cards in their hand matching what was rolled and getting rid of all cards in their hand, rather than matching what they rolled to a point chart.
 It was published by Winning Moves Games USA in 2005 but is no longer in production.
Rummy is a group of matching card games notable for similar gameplay based on matching cards of the same rank or sequence and same suit.
 The basic goal in any form of rummy is to build "melds" which consists of "sets", three or four of a kind of the same rank; or "runs", three or more cards in sequence, of the same suit.
 You can also have mixed runs in all types of rummy so long as all 7 cards are in order.
 The original form of rummy is called Sai rummy, Straight Rummy, Standard Rummy, Traditional Rummy, or Basic rummy.
 The Mexican game of Conquian is considered by games scholar David Parlett to be ancestral to all rummy games, which itself is derived from a Chinese game called Khanhoo and, going even further back, Mahjong.
 The Rummy principle of drawing and discarding with a view to melding appears in Chinese card games at least in the early 19th century and perhaps as early as the 18th century and is, in fact, the essence of Mah-jong.
 Rummy is also very popular in India.
 It is most likely that Indian Rummy is an extension of Gin Rummy and Rummy 500 which originated from the USA.
 It is played with 13 cards, one or two decks, two or more players and with or without jokers.
This is a partial list of games played with domino tiles or similar equipment.
 The most typical domino games are "layout games", i.e. games in which the players add matching tiles from their hand to a layout in the middle of the table.
 These can be either "blocking games", in which the object is to empty one's hand, or "scoring games", in which the players can score during the game by creating certain configurations.
 Other games using domino sets are often adaptations of card games.
 On the other hand, there are also domino-like card games, e.g. Sevens and the once very popular card game Pope Joan.
The 2008 European Championship was the inaugural edition of the Professional Darts Corporation tournament—which thereafter was promoted as the annual European Darts Championship, matching top European players qualifying to play against the highest ranked players from the PDC Order of Merit.
