I won every game but one in a 10 game tournament up until the 9th and 10th game . 9th game I bowled 279 , computer bowled a 300. 10th game , I bowled 278 , computer 300 . I lost 50 pins and the event. I emailed customer service and they were no help and thanked me for my email. Read their responses to the poor reviews , they have a history of no support to their consumers.
