Bonus Bingo is a game offered at Realtime Gaming (RTG) online casinos. It can be accessed from the specialty games section. Bonus Bingo is played in the 75 ball format. 24 numbers randomly chosen from 1 to 75 appear on each card in a 5 x 5 matrix with the center position left blank. 44 balls are drawn at random and the numbers called are marked on the cards. If the marked numbers form the patterns in the payout table then players receive specified payouts. Patterns that contain more numbers pay out more. Some patterns are contained in larger patterns. If patterns overlap then the payout is made for the larger pattern only.
The first choices that the player has in RTG Bonus Bingo are related to card selection. Four cards are automatically displayed on the screen and this is the maximum number of cards that can be played. All cards can be changed by clicking on the Change Cards button. Certain players have lucky numbers and would like to have those numbers on the cards. Therefore players can change cards any number of times till suitable ones are displayed. Players who want to wager with fewer cards can deactivate the cards by clicking on them.
Players have to bet the same amount on all selected cards. The amounts are $0.05, $0.10, $0.25, $0.50 or $1.00. Players should note that the payouts against the patterns are not payout ratios but absolute amounts. These can be seen to change as the players change the bet amount. The lowest payout is for a diagonal line. For a wager of $1 the payout is $1. The largest payout is for a pattern that covers 20 of the 24 numbers. For a wager of $1 the payout is $3,000.
The product of the number of active cards and the bet per card decides the total bet. The combination must be selected carefully keeping in mind the planned number of plays and the total bankroll. In any event once the planned bankroll is exhausted players should stop wagering.
There is one more choice that the player makes. This is whether to play in the normal mode or in the Speed Play mode. In both modes the balls are drawn one at a time. The sound and visual effects are identical in both cases, only faster in the Speed Play mode. It really does not matter which mode is chosen because the difference in time is not significant.
Once the play button is clicked the player has no further role to play. The payouts are automatically credited if winning patterns are drawn. There are some special features available in RTG Bonus Bingo. The first is the Multiplier. The player could randomly be awarded a 2x or a 3x multiplier. He would then have to select one of the active cards on which this would apply. All payouts on that card would be doubled or tripled as the case warrants. With all cards turned on Mystery Balls can be drawn randomly at any time. These special balls award extra credits. Hence it is advisable to wager with all cards activated.
