Bingo equipment
The numbers which are called in a game of bingo, may be drawn utilizing a number of methods to randomly generating the ball call. With the expansion of computer technology in bingo, electronic random number generators are now common place in most jurisdictions. However, some jurisdictions require mechanical ball draws which may utilize a randomly shuffled deck of bingo calling cards, a mechanical ball blower that mixes ping pong balls with blown air or a cage which is turned to mix small wooden balls. All methods essentially generate a random string of numbers by which players match to their bingo cards.
