sentences: Pachinko (パチンコ ) is a type of mechanical game originating in Japan and is used as both a form of recreational arcade game and much more frequently as a gambling device, filling a Japanese gambling niche comparable to that of the slot machine in Western gaming.
 A pachinko machine resembles a vertical pinball machine, but is different from Western pinball in several ways.
 First, a pachinko machine uses small (11mm diameter) steel balls, which are rented to the player by the owner (usually a "pachinko parlor," featuring many individual games in rows), while pinball games use a larger, captive ball.
 The pachinko balls are not only the active object, but are also the bet and the prize.
 The player loads one or more balls into the machine, then presses and releases a spring-loaded handle, which is attached to a padded hammer inside the machine, thus launching the ball into a metal track.
 The track guides the ball around the edge of the playing field, then when the ball loses momentum, it falls into the playing field from near the top.
 Some pachinko machines have a bumper to bounce the ball as it reaches the top, while other machines allow the ball to travel all the way around the field, to fall on the second time that it reaches the top.
The Boys in Blue is a 1982 British comedy film directed by Val Guest and starring Tommy Cannon, Bobby Ball, Suzanne Danielle and Roy Kinnear.
 It is loosely based on the 1938 Will Hay film "Ask a Policeman", which Guest co-wrote.
 Some policemen who have failed to make any arrests are threatened with dismissal, and begin to invent crime to justify their existence.
 It was the final feature film that Guest directed.
Cannon and Ball's Casino (also known as "Casino") was a short-lived variety programme hosted by the veteran comedy team of Tommy Cannon and Bobby Ball.
 It was described as part comedy-show, part game-show and aired on Saturday evening at 6.10 pm.
 The guests were entertainers such as Mike Osman, Gilbert O'Sullivan, Roxette and Big Country.
In baseball, a ground ball pitcher (also ground-ball pitcher or groundball pitcher) is a type of pitcher that has a tendency to induce ground balls from opposing batters.
 The average ground ball pitcher has a ground ball rate of at least 50% with extreme ground ball pitchers maintaining a ground ball rate of around 55%.
 Pitchers with a ground ball rate lower than 50% may be classified as flyball pitchers or as pitchers who exhibit the tendencies of both ground ball and fly ball pitchers.
 Ground ball pitchers rely on pitches that are low in the strike zone with substantial downward movement, such as splitters and sinker balls.
Thomas Derbyshire, known professionally as Tommy Cannon (born 27 June 1938), is an English comedian and singer.
 He is best knows as the straight man of comedy double act Cannon and Ball, along with Bobby Ball.
 He is most well known for the show "The Cannon and Ball Show".
Goalkeeper, often shortened to keeper or goalie, is one of the major positions of association football.
 It is the most specialised position in the sport.
 The goalkeeper's primary role is to prevent the opposing team from successfully moving the ball over the defended goal-line (between the posts and under the crossbar).
 This is accomplished by the goalkeeper moving into the path of the ball and either catching it or directing it away from the vicinity of the goal line.
 Within the penalty area goalkeepers are able to use their hands, making them (outside of throw-ins) the only players on the field permitted to handle the ball.
 The only time when a goalkeeper is not allowed to use their hands inside their box is when a field player of their own team does a direct pass.
 The most common way to know that it is a direct pass, and not an indirect pass, is when the field player has control of the ball.
 Goalkeepers are allowed to pick up the ball during an indirect hit from a teammate (headers, chest, knee thigh, and when the ball bounces off the player).
 Goalkeepers usually perform goal kicks, and also give commands to their defense during corner kicks, direct and indirect free kicks, and marking.
 Goalkeepers play an important role in directing on field strategy as they have an unrestricted view of the entire pitch, giving them a unique perspective on play development.
 If an attacker on the opposing team obstructs the keeper from catching or saving the ball, for example, in a corner, it will normally be a free kick.
The Cannon and Ball Show was a successful comedy variety show on ITV featuring the double act comprising Bobby Ball and Tommy Cannon.
The Minié ball, or Minni ball, is a type of muzzle-loading spin-stabilized rifle bullet named after its co-developer, Claude-Étienne Minié, inventor of the Minié rifle.
 It came to prominence in the Crimean War and American Civil War.
 The development of the Minié ball was significant because it was the first projectile which was small enough to be easily put down the barrel of a rifled long gun.
 Rifling – the addition of spiral grooves inside the gun barrel, which imparted a spin to the bullet – greatly increased the range and accuracy of the gun.
 Prior to the Minié ball, bullets had to be jammed down the rifle barrel, sometimes with a mallet, and after a relatively small number of shots, gunpowder residue built up in the spiral grooves, which then had to be cleaned out.
 Both the American Springfield and the British Enfield rifles – the most common rifles used during the American Civil War – used the Minié ball.

 They hosted their own ITV show "The Cannon and Ball Show" for nine years between 1979 and 1988.
