Badminton is a racquet sport played by either two opposing players (singles) or two opposing pairs (doubles), who take positions on opposite halves of a rectangular court that is divided by a net. Players score points by striking a shuttlecock with their racquets so that it passes over the net and lands in their opponents' half of the court. A rally ends once the shuttlecock has struck the ground, and the shuttlecock may only be struck once by each side before it passes over the net.

The shuttlecock is a feathered projectile whose unique aerodynamic properties cause it to fly differently from the balls used in most racket sports; in particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly than a ball. Because shuttlecock flight is strongly affected by wind, competitive badminton is always played indoors. Badminton is also played outdoors as a casual recreational activity, often as a garden or beach game.

Badminton is an Olympic sport with five competitive disciplines: men's and women's singles, men's and women's doubles, and mixed doubles, in which each pair is a man and a woman. At high levels of play, the sport demands excellent fitness: players require aerobic stamina, strength, and speed. It is also a technical sport, requiring good motor coordination and the development of sophisticated racket skills.

Tennis is a game played between two players (singles) or between two teams of two players (doubles). Players use a stringed racquet to strike a hollow rubber ball covered with felt over a net into the opponent's court.

The players (or teams) start on opposite sides of the net. One player is designated the server, and the opposing player, or in doubles one of the opposing players, is the receiver. Service alternates between the two halves of the court.

For each point, the server starts behind his baseline, between the center mark and the sideline. The receiver may start anywhere on their side of the net. When the receiver is ready, the server will serve, although the receiver must play to the pace of the server.

In a legal service, the ball travels over the net (without touching it) and into the diagonally opposite service box. If the ball hits the net but lands in the service box, this is a let service, which is void, and the server gets to retake that serve. The player can serve any number of let services in a point and they are always treated as voids and not as faults. Let services are extremely unusual, and placing more than one let service in a single point takes a considerable amount of skill or luck. If the first service is otherwise faulty in any way, wide, long or not over the net, the serving player has a second attempt at service. There is also a "foot fault" which occurs when a player's foot touches the baseline or an extension of the center mark before the ball is hit. If the second service is also faulty, this is a double fault and the receiver wins the point. However, if the serve is in then it is considered a legal service.

A legal service starts a rally, in which the players alternate hitting the ball across the net. A legal return consists of the player or team hitting the ball exactly once before it has bounced twice or hit any fixtures except the net provided that it still falls in the server's court. It then travels back over the net and bounces in the court on the opposite side. The first player or team to fail to make a legal return loses the point.

Poker is a popular type of card game in which players gamble on the superior value of the card combination ("hand") in their possession, by placing a bet into a central pot. The winner is the one who holds the hand with the highest value according to an established hand rankings hierarchy, or otherwise the player who remains "in the hand" after all others have folded (the player who makes an un-called bet.).

Poker has many variations, all following a similar pattern of play. Depending on the variant, hands may be formed using cards which are concealed from others, or from a combination of concealed cards and community cards.

In casual play, the right to deal a hand typically rotates among the players and is marked by a token called a 'dealer' button (or "buck"). In a casino, a house dealer handles the cards for each hand, but the button (typically a white plastic disk) is rotated clockwise among the players to indicate a nominal dealer to determine the order of betting.

One or more players are required to make forced bets to create an initial stake for which the players will contest. The dealer shuffles the cards, cuts, and deals the appropriate number of cards to the players one at a time. Cards may be dealt either face-up or face-down, depending on the variant of poker being played. After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt. At the end of each round, all bets are gathered into the central pot.

At any time during a betting round, if a player makes a bet, opponents are required to fold, call or raise. If one player bets and no opponents choose to call (match) the bet, the hand ends immediately, the bettor is awarded the pot, no cards are required to be shown, and the next hand begins. This possibility of winning a pot without showing a hand makes bluffing possible. Bluffing is a primary feature of poker, one that distinguishes it from other vying games and from other games that make use of poker hand rankings.

At the end of the last betting round, if more than one player remains, there is a showdown, in which the players reveal their previously hidden cards and evaluate their hands. The player with the best hand according to the poker variant being played wins the pot.

Table tennis is a sport where two or four players hit a ball with paddles back and forth to each other on a table, in a manner similar to tennis. The rules are slightly different, but the concept is quite similar. In singles play, the ball is not required to cross from the server's right-hand court to the receiver's right-hand court (or left to left) as it is in tennis. However, serving across is required in doubles play. Ball spin, speed, placement, strategy and tactics play an important part in competitive table tennis matches. The speed of the ball can vary from slow serves with much spin to smashes that travel as fast as 112.5 kilometers per hour (69.9 miles per hour).[4]

The game is played on a 274 cm (9 ft.) × 152.5 cm (5 ft.) × 76 cm (2.5 ft.) high playing surface. The International Table Tennis Federation requires an area not less than 14 m (46 ft) long, 7 m (23 ft) wide and 5 m (16 ft) high for competitions. No limitations in size or shape are specified. Modern paddles usually have a thin layer of rubber covering the paddle's striking surface. The rubber may have pimples pointing outwards or inwards, as well as a thin layer of sponge between the plywood center and the rubber surface. Since spin plays a large role in the modern sport of table tennis, the composition of the rubber and the combination of sponge and rubber is designed to maximize the amount of spin and speed a player can impart onto the ball. Other technological improvements include the use of carbon or other synthetic layers as part of the blade to increase the size of the sweet spot or the stiffness of the blade.

The ball used in table tennis has a diameter of 40 mm, is made of celluloid, and is completely hollow. A three star rating on a ball usually implies a top quality ball, in relation to its bounce, roundness and their respective consistency between balls of the same make and type.

The winner is the first to score 11 points, with each player alternating serves every two points. At 10-10 (or deuce) the players alternate with every serve; the winner is then the first person to gain a clear two points advantage over his opponent. The 11 point game is an International Table Tennis Federation (ITTF) change which occurred in 2001. All games played at national level and at international tournaments (ITTF) are played to 11 points in either a best of five (5) games (preliminaries) or best of seven (7) games format (championship matches).

Ever since I started to learn it, Poker is a really fun game, so that gets my vote.

I suppose that depends on your definition of sport.

poker is the greatest sport man has ever invented and nobody is going to tell me it isn't a sport
