Roubingo™ is a variation of the traditional paper bingo game commonly referred to as B & O Bingo.

Players who daub and claim the winning pattern within the first two balls get a payout amount of 36 times their purchase price.

Each game requires at least two players and can accommodate up to seven players. A player walks up to the table and exchanges money for playing chips.

A player can buy a single card by placing a chip(s) in the middle of any squares on the interior of the grid.

A player can buy two cards by placing a chip(s) between any two squares on the interior of the grid.

A player can buy three cards by placing a chip(s) on the exterior side of any row of squares.

A player can buy 4 cards by placing a chip(s) at the intersecting corners
of 4 squares on the interior of the grid.

A player can buy 6 cards by placing a chip(s) on the exterior side between any two rows of squares.

A player can also purchase the 767 card that is featured at the top of the felt. This card's winning pattern is B7 and O67. Because there are 6 each of the B1B6 and the O61O66 balls and only one each of the B7 and the O67 balls in the blower, the odds are much longer  the frequency of a bonus 767 card bingo within the cycle is 1 out of 1,369!
The payout is 1,000 times the purchase price of the card. For example, if a player purchased a winning 767 card for $1 and correctly claimed the bingo pattern, the Casino would retain the $1 paid for the card and pay the player $1,000.
Once the players have finished purchasing the cards and packs of cards, the caller signifies that no more purchases are allows for that game. The caller then draws and announces the first “B” and then draws and announces the first “O.” Players then daub the corresponding numbers on their cards and claim a winning bingo pattern if they have one. (Note: Depending on jurisdictional and house rules, each player may have the entire perm deck of all 39 cards in front of them to find the card(s) they have purchased, to be able to daub the card(s), and to be able to claim their bingo.)
Once a winning pattern is claimed and verified, the caller will place a marker on the accounting grid to identify the winning card. All of the purchases are collected and the winning bingo payout, if any, is paid for the winning card. If no player(s) has or claims a winning bingo pattern in the first draw sequence of B’s and O’s, subsequent B’s and O’s are drawn until a player has, and claims, a winning bingo pattern. Winning patterns claimed after the first drawn B and first drawn O are paid out at a fixed, consolation amount.
After all purchases are collected and prizes are paid, out the grid is cleared and players can begin purchasing cards for the next game.
