Bonus Bowling is a game found at Internet casinos using Playtech software. The game can be found under the Arcade Games menu. This is a simple game of luck in which the player bets on the outcome of a clearly bad bowler, one frame at a time. A more detailed explanation follows.
As in slots or video poker once a wager is made it is never returned. So all pays indicated are on a "for one" basis.
The player has five betting choices on the next frame of bowling: 0-3 total, 4-6 total, 7-9 total, spare, and strike. The player may bet any number of these and in different amounts.
Following are probabilities of each outcome.
- Strike: 3.4%
- Spare: 8.56%
- 7 to 9: 17.04%
- 4 to 6: 28.4%
- 0 to 3: 42.6%
One frame out of three is a "Golden Frame." If the player throws a strike in a Golden Frame (regardless of what he bet on) he will win a bonus of ten times his bet.
In the screenshot above I bet $5 on a strike and also had a golden frame. So my total win was $5*25 + $5*10 = $175.
