In the second quarter, 15% of BetMGM's new players came from MGM and 31% of MGM M life sign-ups came from BetMGM.
Further, 11 of our 17 domestic properties had all-time record quarters and slot gross win.
Consider the entertainment programming a few weekends ago, we had Garth Brooks at Allegiant Stadium, we had a McGregor fight at T-Mobile and Bruno Mars at Park MGM, selling over 98,000 tickets within our properties distance situated to capture significant amount of this foot traffic.
Our consolidated second quarter net revenues were $2.3 billion, significantly better sequentially over our first-quarter results.
Our net income attributable to MGM Resorts was $105 million, and our second-quarter adjusted EBITDAR improved sequentially to $607 million -- $617 million, once again, heavily driven by our domestic operations.
Our Las Vegas strip net revenues in the second quarter were $1 billion, 31% below the second quarter of 2019 and 28% below, excluding Circus Circus Las Vegas, which was sold at the end of 2019.
Our second-quarter adjusted property EBITDAR was $397 million, which is 5% below the second quarter of 2019 and just 1% lower, excluding Circus.

Our second-quarter slot handle was 23% greater than that of the second quarter of 2019 on an apples-to-apples basis, excluding Circus Circus.
Our second-quarter occupancy was 77%, an improvement from 46% in the first quarter with weekends and weekdays at 94% and 70%, respectively.
June occupancy was 83%, with weekends and weekdays at 96% and 79%, respectively.
July occupancy was 86%.

Much like in Las Vegas, we're driving success in casino, with second-quarter casino revenues outpacing 2019 levels by 8%, primarily due to slots and our higher-end customer base.
Our 50 to 64 age demographic, of which I'm a proud member, is now at 2019 levels, and we're attracting more of the 65-plus age demographic.
Our second-quarter regional margin of 37% was also an all-time record, growing 855 basis points over the second quarter of 2019 and sequentially by 316 basis points over the first quarter.
