Table shuffleboard (also known as American shuffleboard, indoor shuffleboard, slingers or shufflepuck) is a game in which players push metal-and-plastic weighted pucks (also called weights) down a long and smooth wooden table into a scoring area at the opposite end of the table. Shooting is performed with the hand directly, as opposed to deck shuffleboard's use of cue sticks.
Shuffleboard tables vary in length, usually within a 9–22-foot range (2.7–6.7 m), and are at least 20 inches (510 mm) wide. Tables are intended to be kept level, but any given table may have its own slight slope, adding an extra challenge. In order to decrease friction, the table is periodically sprinkled liberally with tiny, sand-like beads of silicone (often referred to as shuffleboard wax even though silicone is not a wax, or sometimes as shuffleboard sand, or shuffleboard cheese, due to its visual similarity to grated cheese). These beads act like ball bearings, letting a puck slide down the table a great distance with only a slight push.
Each end of the table is divided into three scoring sections by straight lines across the width of the table. The scoring sections extend from the very edge of either end of the table towards the middle of the table, covering approximately one-third of the length of the table. The outer scoring section, at the very end of the table, covers approximately 4 to 5 inches (100 to 130 mm) from the edge, and is labeled with the number "3" in the middle (for "3 points"). The next section is adjacent to this section, of equal length, and is labeled with a "2." The final section, "1", is adjacent to section "2." This section is about 4 times the length of either of the first two sections. The center third of the table is unmarked. The line that separates the center third of the table and the beginning of the "1 point" section is called the "foul line" (a weight which does not pass the foul line closest to the player is removed from the table for the round). The table is surrounded by a gutter, or "alley"; pucks that accidentally fall, or are knocked, into a gutter are out of play for the rest of the round.
Game play 
In general, players take turns sliding, or "shuffling," the weights to the opposite end of the board, trying to score points, bump opposing pucks off the board, or protect their own pucks from bump-offs. Points are scored by getting a weight to stop in one of the numbered scoring areas. A weight has to completely cross the zone line to count as a full score(if a weight is partially in zone 2 and 3 the weights score is 2). A weight that's hanging partially over the edge at the end of the table in the 3-point area, called a "hanger" (or sometimes a "shipper"), usually receives an extra point.
Weights that haven't passed the foul line closest to the player are removed for the round. Pucks that fall off or are bumped off the table into the gutter are removed from play for the round. No points are tabulated until the end of the round.
When all weights have been shuffled, the player with the puck closest to the far edge of the table takes points for all pucks that are ahead of their opponent's furthest shot. The other player does not take points. For example: there is a red puck in 3, a red in 2, a blue in 1, and two red pucks in 1 but further away from the end of the table than the blue puck. Red player would receive 5 points, blue player does not score. The player who does not score will shoot first the next round.
In 1974, Reginald Charles Gilchrist invented the digital scoring unit for table shuffleboards while president of Universal Shuffleboards, one of the companies he founded.
Object of the game 
The objective of the game is to slide, by hand, all four of one's Weights alternately against those of an opponent, so that they reach the highest scoring area without falling off the end of the board into the alley. Furthermore, a player's Weight(s) must be farther down the board than his opponent's Weight(s), in order to be in scoring position. This may be achieved either by knocking off the opponent's Weight(s), or by outdistancing them. Horse collar, the most common form of the game, is played to either 15 or, more typically, 21. Below is an image of the weights on the board. Only the weights in front score.
In one-on-one, each player is assigned a color of puck (4 pucks per player). Play begins at one end of the table, and each player alternates shuffling one weight at a time down towards the opposite end of the table (which becomes the "scoring end" of the table), until all 8 pucks have been shuffled. Each player tries to either land his puck closest to the end of the table, knock the opponent's pucks off the table, knock their own puck into a higher scoring area, or position a puck so that it will block their opponent from being able to hit another puck off the table.
This finishes the "round." Play then continues from the other end of the table, where the pucks have come to rest. When a set number of points has been reached by a player (often 15 or 21), that player has won that "frame." A "match" consists of a predetermined number of frames.
In two-on-two, teammates stand on the opposite end of the table and play every other round, shooting from alternating ends of the table (i.e. two games are effectively played at once, with team scores combined). Sometimes players will switch to the other end of the table between frames.
An unofficial but common variation has all players at one end of the table. Each player will have 2 weights/shots per round. Teams alternate turns, with each teammate shooting every other turn.
While there are some official rules agreed upon by shuffleboard organizations, players should be aware that it can be a very informal and spontaneous game, and as such, regional variations and house rules abound. There are some differences by country, as well.
In Canada, the game is played under rules approved by the Canadian Shuffleboard Congress. Except in certain tournaments, in one-on-one play, games are played to 15. Two-person teams compete until one team reaches 21 points. In both cases, a frame consists of four stones (pucks) per player.
Bankboard/Cushion Shuffleboard/Bumper Shuffleboard 
A variant of table shuffleboard, more clearly related to billiards and air hockey, is bankboard (often simply called shuffleboard by its players), in which the player may bounce the puck off one of the rubber cushions or banks that run the length of both long sides of the table (in place of gutters), e.g. to go around an interfering puck. Bankboard tables are within the shorter range of table sizes (usually 12–13 ft long) and so can be useful for maximizing revenue per square foot of floorspace in a bar or other venue.
A Dutch variation known as sjoelen, apparently influenced by bagatelle (a billiards offshoot and pinball ancestor), bar billiards, skeeball, miniature golf and related games, makes use of a long, unidirectional board placed on a table in which the goal is to slide 30 wooden pucks towards the end of the board and try to have them enter through small open doorways or arches into numbered scoring boxes. Each player has 3 sub-turns to get as many pucks in the scoring boxes. The boxes are numbered from left to right: 2, 3, 4 and 1. The most intriguing rule is that for each set of pucks (a puck in every box) they count double so instead of 10 points for a set you will get 20 points for each set. The maximum score is 148 which is accomplished by getting 7 pucks in 2, 7 pucks in 3, 9 pucks in 4 and 7 pucks in 1. It totals to 7 × 20 + 4 + 4 = 148. The most famous manufacturers of sjoelbakken (sjoelen boards) are Homas, Heemskerk Sport and Schilte, who mass-produce the game for the continental European market and more recently North America.
Shove ha'penny 
An even more miniaturized, related British game, with a much less elongated board and many more scoring zones, is played with coins and known as shove ha'penny. An evolutionary relationship between the game variants is uncertain.
Bonus Shuffle 
In the 1979-1980 version of Beat the Clock which aired on CBS and was hosted by Monty Hall, the final round of the main game was called Bonus Shuffle, a game of table shuffleboard where the two teams attempted to throw disks to win cash from $300–$1,000. The team whose disk was the farthest won the game and the chance to play the Bonus Stunt for 10 times their Bonus Shuffle amount from $3,000-$10,000.
