Question: In what game do players take turns removing one block at a time from a tower constructed of 54 blocks, Jenga or 30 Seconds?
Context: Jenga is a game of physical skill created by Leslie Scott, and currently marketed by Hasbro.  Players take turns removing one block at a time from a tower constructed of 54 blocks.  Each block removed is then placed on top of the tower, creating a progressively taller and unstable structure. Words with Friends is a multi-player word game developed by Newtoy.  Players take turns building words crossword puzzle style in a manner similar to the classic board game "Scrabble".  The rules of the two games are similar, but "Words with Friends" is not officially associated with the "Scrabble" brand.  Up to 30 games can be played simultaneously using push notifications to alert players when it is their turn.  Players may look up friends either by username or through Facebook, or be randomly assigned an opponent through "Smart Match".  Players can also find potential opponents using Community Match. Chomp is a two-player strategy game played on a rectangular chocolate bar made up of smaller square blocks (cells).  The players take it in turns to choose one block and "eat it" (remove from the board), together with those that are below it and to its right.  The top left block is "poisoned" and the player who eats this loses. Broadsides and Boarding Parties is a board game published by Milton Bradley in 1984 as part of their Gamemaster series.  It was the 3rd in the series of games that are all designed by Larry Harris.  It is the only game of that series to feature a two player game (all of the games in the Gamemaster series were for two or more players), "Broadsides and Boarding Parties" is a duel between a Spanish galleon and a pirate ship.  Players take turns moving their ship and firing at the other ship to sink her.  If the ships collide then players may take boarding parties onto the other ship to try to win. 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. Wythoff's game is a two-player mathematical game of strategy, played with two piles of counters.  Players take turns removing counters from one or both piles; when removing stones from both piles, the numbers of counters removed from each pile must be equal.  The game ends when one person removes the last counter or counters, thus winning. Subtract-a-square (also referred to as take-a-square) is a two-player mathematical game of strategy.  It is played by two people with a pile of coins (or other tokens) between them.  The players take turns removing coins from the pile, always removing a non-zero square number of coins.  The game is usually played as a "normal play" game, which means that the player who removes the last coin wins.  It is an impartial game, meaning that the set of moves available from any position does not depend on whose turn it is.  Solomon W. Golomb credits the invention of this game to Richard A. Epstein. In game theory, the centipede game, first introduced by Robert Rosenthal in 1981, is an extensive form game in which two players take turns choosing either to take a slightly larger share of an increasing pot, or to pass the pot to the other player.  The payoffs are arranged so that if one passes the pot to one's opponent and the opponent takes the pot on the next round, one receives slightly less than if one had taken the pot on this round.  Although the traditional centipede game had a limit of 100 rounds (hence the name), any game with this structure but a different number of rounds is called a centipede game. Life pool was a form of pocket billiards (pool) mainly played in the 19th century.  It was one of several pool games that were popular at this time (so called because gamblers pooled their bets at the start of play).  The object of the game was to be the last player left "alive" and therefore scoop the pool (take the winnings).  Each player had three "lives" to begin with and would lose one when another player potted their <dfn id="">coloured ball</dfn> which was designated to them at the start of the game.  Using the same number of balls as players, players take turns striking their designated ball with the cue in an attempt to collide that ball with one (or more) of their opponents' balls knocking the opponent ball into a pocket.  Once a player lost their three lives, they were declared "dead", i.e. out of the game.  The game continued in this way until there was only one player left, who was declared the winner.  Around 1875, life pool merged with black pool to form the new game of snooker, today one of the most popular cue sports in the world. 30 Seconds is a fast-paced general knowledge game.  Players generally play in teams of two to sixteen.  One player must guess a word from their teammate's explanation, much like Charades, with the aim to guess as many possible answers in 30 seconds.  The main restriction on the explanation is that it may not contain the actual word or part of the word.
