People who did not manage to get tickets the first time around are being given a fresh chance to book a place at Glasgow 2014, with a second round of sales having opened at 10am today.
While some people went online to express delight at netting the tickets of their choice, others took to Twitter to report delays of "more than 60 minutes" as they tried to book seats online.
The official Glasgow 2014 Twitter account welcomed people's patience amid the strong demand.
One message said: "We're experiencing very high demand for £2014tickets. The site is up and selling but the queues are large and we appreciate your patience."
Another message said: "Call volumes to the ticketing hotline are very high. If you have access to the web, you could also try https://tickets.glasgow2014.com."
At the start of today, some tickets were still up for grabs for 12 out of the 17 sports taking place, including badminton, hockey, rugby sevens, weightlifting and netball.
People who took part in the original application phase have the chance to buy any of the remaining tickets which are being allocated on a first-come, first-served basis via the official ticketing website or ticket hotline.
Applicants who got no tickets in the application phase have exclusive access to buy today and tomorrow.
From Wednesday the sale is opened up to people who got some of the tickets they wanted, then all the Glasgow 2014 ticket applicants are invited to buy tickets until 6pm on Saturday October 26. Any remaining tickets will then be put on general sale.
During the recent four-week allotted window for ticket applications, there were 2.3 million requests for up to one million tickets.
Proving particularly popular from the sports on offer was track cycling, receiving 25 times more requests than the number of tickets available.
There was also an excess of 100,000 applications made for the 100m men's final at Hampden Park.
Other sports which are oversubscribed include diving, swimming, mountain biking, artistic gymnastics, judo, shooting and triathlon.
Ty Speer, deputy chief executive of Glasgow 2014 said recently: "We're all set for this exciting new phase of ticketing during which there may be periods of high demand as people select and buy their sports and sessions. At these times we'd appreciate the patience of all customers. We will be working hard to process all orders as quickly as possible."
