Ninja Bowling (2015)

Set up:
Pick a color.
Set up the bowling pin cards in a triangle like shown. Put your strike/spare cards off to the side. Hold your star cards in your hand.

Play:
Each player throws a card at their pins to see who goes first.
Whoever is touching the most cards gets to go first.
If there is a tie, keep throwing to someone gets more.

You take turns throwing your cards. Your hand can not go past the front pin of the pins in front of you.
The winner of the previous round goes first.
If you get a spare (win a round), then win another round. That spare becomes a strike, just flip it over.

Scoring:
Each round each player throws 3 star cards. Whoever touches the most combined cards wins a spare. If the player touches all the cards over the course of the 3 throws, they will get a strike card. First person to get 3 strike cards wins. All ties void each other out for each round.

Alternative.
If you want to add a new challenge use the numbers on the back of the cards to score points. You get points for the cards you land on. You can play to a predetermined score. Or you can win unless you have more points than your opponent.
