I have listed all the rules in a clear way by dividing them into 3 paragraphs:
1) The very basic rules for Bingo for you to remember or recollect;
2) Online Bingo rules and all differences you may find;
3)The differences between 75-ball (North American) and 90-ball (UK, Europe, Parts of Austrailia) games, in order to make everything clear.

1. The very basic rules for Bingo for you to remember or recollect.
Firstly, you should know that Bingo is the game of chance with its numbers selected randomly. A player writes down the numbers which he or she thinks are the most probable and then bingo numbers are announced. The winner is one who made a specified order of numbers on their card from the numbers which have been called, calls out "Bingo!" and wins! Simple? What is also worth to be mentioned, in the beginning of the game, each bingo player is provided a card marked with a grid containing numbers. Remember, there are no two players cards which are similar to each other, as everyone has a unique strategy. What is only one thing similar is the fact that the numbers on them are in a 5x5 grid corresponding to the five letters of B-I-N-G-O. Further into details, a typical bingo card is composed of 24 numbered spaces and one free space that can be marked. The numbers in column "B" are between 1 and 15; column "I", 16-30; column "N", 31-45; column "G" 46-60; and column "O", 61-75. No something more about the game. At the start, the organizer(s) allow the pattern to be formed on the card at the start of the game and the "caller" then begins selecting numbers (usually from a container of some sort - once selected, the number is put aside not to be used again). Than players check their numbers, and if it exists, he/she highlights it on the card. Basically, the only element of skill involved is the ability to search and mark one's card quickly enough to be ready for the next number and/or be the first to call out "Bingo!" Easy?
The next part of the game is the moment when the caller, after continuing to look for and call numbers, finally forms the specified pattern and shouts out “Bingo!”. However, there are many patterns. Some of the most popular are: one line/two lines (one or two lines on the grid completely marked with selected numbers) or Full House/Full Card/Blackout/Cover-all (attained when ALL the numbers on a card are covered). What is very important in the game, organizers can choose their own way of the patterns required for a particular game – for example by requiring patterns in the shape of a letter, or other different designs. Prizes vary from large payments to small amounts.

2. Online Bingo rules and all differences you may find.
For first, it is not true that online bingo varies significantly from its traditional ancestor. What is more, it is almost the same game with some additional 'modern' changes that can't be found previously. What makes the online version of the game even more attractive could be the fact that no matter where you are, you can play it easily. Frankly, it is much easier than the traditional game. All it takes is to log on and you're already able to play sitting comfortably in your armchair! However, there are some differences between the two varieties and in many cases, these differences make the online bingo games even more attractive. Online version of bingo uses random numbers generator (similar to that used in online poker sites) instead of contraptions used in a traditional game. Other differences include the 'auto-daub' feature online where players can check a box and have their numbers automatically daubed/marked without having to do so themselves. Another important thing is the fact that players have access to "Best Card Sorting" and "Best Card Highlighting". What is the advantage if that? This will automatically point out a player's cards which are closest to bingo. Isn’t it interesting? Another difference between the online and traditional game is "chatting". In land-based casinos talking is usually forbidden but online, operators encourage communication at the table, and have made it easy for players to chat with others. There is no differences between  rewards online and those traditional. Although many players claim that playing online is even more profitable for them. What is more, there are progressive jackpots which can bring you more and more winnings after playing for a long time. So, to conclude it is worth to be advanced player and have your own favorite site because as a steady visitor you can achieve more actually than players who skip from one site to the other.

3.The differences between 75-ball (North American) and 90-ball (UK, Europe, Parts of Australia) games, in order to make everything clear.
There are 2 types of bingo that players from around the world can generally choose from: 75-ball and 90-ball games. North America plays 75-ball (5x5 card w/ free space) while the UK and other parts of the world play 90-ball (9x3 card). To add up, both varieties are really popular all over the world. It does not matter which pattern you are supposed to play with, the aim of 75-ball always remains the same: mark off the numbers to get the needed pattern. On the other hand, in 90-ball, each card has 3 horizontal lines and nine vertical. Each line has 5 numbers which means each card then has 15. The 1st column contains numbers 1-10; the 2nd, 11-20; 3rd, 21-30; and so on and so forth up until 81-90 in the 9th column. Usually the game of 90-ball bingo is played in 3 stages: one line, two lines, and Full House. In a one line game, players need to complete a full horizontal line across one card (= 5 numbers marked) whereas a two line game requires, you guessed it: completing any two marked lines horizontally across one card (= 10 numbers). At the end of the game the "Full House" requires all of the numbers to be marked off (= all 15) just like in a normal 75-ball 'Cover-all' game. Obviously, the Full House is the biggest winning one can win. To sum up, as you can see, there are many possible ways of playing online bingo, and which to choose depends on your own preferences.
