Bonus Bowling

Introduction

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.

Rules

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.
