A bowling league is a group event where several teams bowl against each other over the course of a season. Most bowling leagues consist of four to five team players that meet up once a week or once every other week, usually at the same day and time. ... In most bowling leagues each team plays three games per scheduled match.

One game of bowling lasts around 45 minutes to 1 hour with 5-6 people per lane. Leagues typically consist of three games.

Generally the cost is between $13 - $20 per person per week, which includes bowling fees and contribution to prize funds. Some leagues are as little as $10 per week, but do not include much prize money.

Begin by Subtracting your average from the Basis Score(220-170 = 50) , then multiply that number by the Percentage Factor(50 x 80% = 40). Your handicap is 40. So, the first game bowled in your league you bowl a 160, you would add your 40 point handicap to that score and 200 would be your adjusted score.
