If you are bowling by yourself, one game of bowling can take up to 20 minutes depending on if you are striking. It also depends on how fast you are bowling and if you take your time at the foul line and if you are wiping off your bowling ball. If you are bowling with other people, this will take longer. On a 5 man bowling league team, it takes about 3 to 4 hours to bowl 3 games but it depends on other people and how fast they bowl.
