Is there any other game format in bowling besides baker or petersen points system?

Yes there are other Bowling formats.The Baker System, Scotch Doubles.

Also the Petersen Point System is a scoring "System" used in bowling, not a how it's bowled format. It's often confused with the widely used match point system of scoring.

The Baker System format places emphasis on the team effort rather than individual accomplishments

of team members. All team members follow each other in regular order to bowl a single game. For a

5-player team, Player #1 bowls frames 1 and 6; #2 bowls 2 and 7; #3 bowls 3 and 8; #4 bowls 4 and

9; and #5 bowls the 5th and 10th frames.

Scotch Doubles

Any combination of two bowlers is allowed. A three-game series is bowled with Bowler A bowling first in each

frame and Bowler B bowling at whatever pins are left. If a strike is bowled, the same bowler would continue.

Bowler A starts the first and third games, Bowler B starts the second game.
