3on Bingo Paper is bingo paper that contains 3 bingo faces aligned either vertically (up and down) or horizontally (side to side). The 3on paper comes in packs of 1000 sheets, and each sheet contains 3 bingo faces. 3on paper is case paper which means that every sheet in a pack comes in the same color such as blue, red, green, purple, or some other typical color.
 
Unlike 1on bingo paper which is rarily used for commercial games (outside specialty bingo games), 3on bingo paper is often used for commercial games. This is because it allows the serious players to play more faces at one time than a 1on would. This doesn't mean that this paper isn't used for informal gatherings and family events as well. Quite the contrary. 3on bingo paper is used frequently for both styles of games.
 
As its name implies, 3on bingo paper contains three bingo faces or bingo cards (as its name implies) allowing for a bingo player to have 3 plays. If used in a commercial game, they are often sold separately from a game's regular bingo books and sold as extra jackpot sheets to players who want a greater chance to win a large jackpot.
 
As we said, this style of paper lends itself both to commercial and informal games or family gatherings. This is because of its simple design and ease of use. 3on's are great additions to a commercial bingo's regular books, but at the same time are simple enough for a home game. Novice players at informal events won't be overwhelmed when playing 3 faces, and 3 faces isn't too small for serious players as to be irritating. Whether it's a family game or a serious game with novices, everyone should be able to play at least one sheet of 3on bingo paper. 
 
If your looking for a slightly smaller cut of bingo paper than a 3on and you're having a simple, fun, informal gathering, you may want to go with a 1on bingo sheet instead. If you are looking for the next largest common cut of bingo paper, you may choose to go with a 4on bingo paper, a 6V (vertical) bingo paper, or a 6H (horizontal) bingo paper instead.
