As per myth, the origin of Billiards is associated with sixteenth century pawn broker called William Kew. He just put down three different balls and started pushing with a yard measurement stick.

Hence the game initially termed as Billyard as Bill Kew started playing with a yard stick. Similarly, Cue was initially used to call as Kew. But we are not going to past and will start from few decades ago.
Changes are major part of the life and game also has changed a lot. Even in the past three to five decades, we have seen many changes in this game. The time when Wilson Jones and Michael Ferreira ruled the world of green baize, put more stress on In-offs and not potting.
They used to play more and more in-offs, long Jennie, short Jennie, cannons and in very odd situations where almost no other option left, opted to pot the red.
But now, the time of Geet to Pankaj, the game has moved from "D" to Spot. The game is now fast as the players are building breaks on Top Table mostly using pots and cannon leaving in-offs for recovery shots only.
Ahead to this the game has now further changed from time format to point format.
Just like Cricket, the difference between Billiards and Snooker is like a Test Match Cricket and One Day Cricket.
Where Billiards is traditionally rich, stylish and maintains a class, the Snooker is slightly aggressive with a well-defined target having limited time.
The infrastructure and conditions are same as in Billiards but the difference is visit of each player comes faster than in Billiards. Snooker can also be played in doubles and as a team also. Whereas the Billiards played with just three balls and goes on as long as the player delivers his / her skills to stay on table.
Snooker is played with Twenty Two Balls that includes fifteen Red; six different colours (one each of Black, Pink, Blue, Brown, Green and Yellow) and the cue ball.
The frame ends when all these balls potted in terms of rules defined for the same. Billiards has no limit of obtaining points, Snooker’s has maximum 147 point (which is the highest score a player can get in a single frame).
Before the game starts, all the six color balls placed on spots allotted to each color (as described in Section `Equipment – Table’) and Reds in a form of Pyramid between Black and Pink (extremely close to Pink). Rest about how to play the game of Snooker is clarified in Rules Section.
Pool is the shortest version of classic game enjoyed by many for centuries i.e. English Billiards or Snooker. It retains its original six-pocket table but the size of table is shortened and has fifteen different colored balls and one white ball (the cue ball). The fifteen balls are also distinguished by stripes or solids.

In pool, there are a variety of games that can be played. The major ones include 8-ball, 9-ball, rotation and straight pool. In 9-ball, all the balls on the table are solids except for the nine ball. Each ball is pocketed consecutively; however the nine ball maybe pocketed without completing all eight solids if it is pocketed in a combination shot. Rotation is very similar to 9-ball except the players need to pocket all 15 solids/stripes and there is no short way of winning through a combination shot. And the foul penalties for rotation is much more strict. The number on the ball is its point value and once a player has reached a certain amount of points which cannot be reached by the other, he/she wins the game. Straight pool is a very liberal game and each player pockets any ball on the table. The player(s) with the most ball pocketed when a set maximum is reached wins. The 8-ball game’s objective is to take 8 ball after completing your colour which is either solid or striped

Billiards is a much known game for cue sports lovers. Every one is aware with the concept and object of the game of Billiards. 3 Cushion carom is as much similar to billiards and as much different with the object, concept and equipment of the game.

3 Cushion carom is a game in cue sports which is used to play on a pocket-less table which is slightly bigger than a standard Pool table. The size of the table is 10’ x 5’. The Cloth of the table is nap-less and is electronically heated. The cue is similar to Pool Cue. The balls size is also bigger than the balls used in billiards, though they are same in number and color as in Billiards (i.e. White, Yellow and Red). In addition to this, the both the cue balls carry red spots on it as it helps the television audiences to know the amount of spin used on the cue ball.

The object of the game is to make contact of Cue Ball with other two object balls (very commonly known as `Cannon' in Billiards), but the difference is the cannon should also have a contact of cue ball with at least 3 cushion in-between. This can happen in any order as long as the cue ball touches atleast three cushions prior to touching second object ball.
