connected TV and, and over the top bet solution spot on. There are also additional opportunities for inclusion on their quickly growing streaming platform, Peacock. This combination of national and regional networks along with the local, uh, the local TV assets, gives us the ability to create bespoke, bespoke strategies to reach any audience. I'd like to now introduce our Group Chief Operating Officer, Mark Hughes, formally the CEO of Banach Technology. Mark began his career working for Paddy Power, now part, now part of the, now part of the, uh, Flutter Group, I should say, as a pivotal member of the quantitative analytics team. As previously noted, in-play betting is estimated to make up at least 75% in the, uh, U.S. of all sports wagering activity, uh, within the next three years. And PointsBet acquired Banach Technology to take advantage of this in-play opportunity. Mark will highlight the progress we've made in this area, again, over the quarter, uh, uh, integrating the, uh, Banach trading platform. Over to you, Mark. Thank you, Johnny. Now turning to slide 14. In-play is our north star. We believe in the value that sports betting brings in enhancing the viewing experience of a sporting event. And we are building a product to appeal to the users that enjoy that experience. We are on the journey to building an always on experience that drives customer engagement and repeat usage, meaning more player days, more engagement for player day, and ultimately a higher delivery of utility to the customer. Our data shows that in-play delivers the product experience to keep the user engaged and on apps during a session. Our in-play customers demonstrate higher average bet plays to bet more frequently. They have more bets per play day and ultimately a higher average revenue per user. Turning to slide 15. The launch of our enhanced in-house in-play model for NFL in October 2021, represented a big milestone for the company. PointsBet acquired Banach Technology in early 2021, with the intent to accelerate ambitions to deliver a world class in-play betting experience to our customers in the U.S. Banach Technology was founded with the vision to build a modern sports betting technology platform to support the delivery of a more enriched and quality betting experience for the in-play customer in the U.S. Since launching the new in-play NFL model, we have already seen key results when compared to the period immediately prior to release. Firstly, the improved betting experience.New algorithm has reduced the amount of time our in-play product is suspended for betting, by more than 40%. This results in a significant increase in volume of opportunities across time to place a bet. This coupled with improved bet placement journeys have led to a reduction of approximately 50% in bets rejected. Secondly, product expansion. We have increased fourfold, the number of betting markets our players can bet on. This includes the addition of player prop betting markets and the markets first in-play same-game parlay. We also need our customers to show an appetite to engage with this new content. And the early statistics have showed huge promise with a proportion of turnover outside three core betting markets increasing by 42%. Our users want to play this product, and we'll continue to deliver for them. This also offers a proportional increase in cash out opportunities for our customers. And thirdly, results. Our stated north star is in-play, and our hypothesis is that our product improvements will drive our users to better in-play. Since the launch of our NFL model, in-play is a proportion of overall NFL handle has grown by 44%. So continuing to push the boundaries of the customer experience and with integration of the official NFL data from Betgenius, we have seen further improvements in both in-play betting availability and bet delays. January have seen the introduction of our in-house in-play NBA product, and we'll plan a fast follow for our in-house in-play NCAAB model, and an overall improvement in our in-play tennis offering with the introduction of IDF tennis. So forecasting similar improvements on other in-house products and continue to mo- momentum towards our vision to deliver a word class in-play betting experience to our customers. Evidencing our progress during NBC's playoff game on Saturday 15th of January, between the Raiders and the Bengal's Wild Card, we are proud to become the first U.S. sports betting provider to offer clients live in-game betting opportunities with zero suspensions across the core markets of spread and money line. All of the aforementioned initiatives demonstrates our ability to continue to innovate and lead the market with unique and value adding products. Turning to slide 16. I would now like to touch upon iGaming. The iGaming product continues to show strong quarter-on-quarter improvement with net win up 145%. We were particularly excited to have launched our live dealer table solution in Michigan, in November, and New Jersey in December, including blackjack, roulette, and baccarat. Online casino products have seen a rapid product in the U.S. And the experience iGaming team at PointsBet is responsive to our users and eager to bring our customers the experience and gains they're looking for. The introduction of live theater gaming is a welcome addition to PointsBet's growing wagering product suite. Our live gaming options in Michigan offer top tier choices for our players and will serve as a template as iGaming expands in other jurisdictions in the U.S. and Canada. We launched iGaming in West Virginia on January 27th, and anticipate further launches in Pennsylvania and Ontario in the coming months. Importantly, we look forward to the continued product improvements we have in development as we move to the next phase of our iGaming offering, including a significantly enhanced games library, automated promotional functionality, personalized offerings, and other innovations. We will continue to see online casino in customer activity and revenue generation over the coming months. I now I'd like to hand it over to our Group CFO, Andrew Miller. Thanks Mark. Turning to slide 17 for the quarterly four city cash flow summary. As at the 31st of December ' 21, the company's corporate cash balance was $523.3 million. Net cash used in operating activities during the quarter ending 31 December, excluding the movement in player cash accounts, was $56 million. I'll now walk through each of the main line items. Receipts from customers for the quarter totaled $90.4 million. This includes net win from sports book and iGaming verticals of $77.3 million as previously presented by Sam and Johnny, and a balance of $13.1 million includes cash receipts from our European B2B operations, cash receipts from our U.S. rating ADW business, and a partial New York license fee reimbursement received from Resorts World Bet, a subsidiary of the Genting Group, as part of our B2B platform provider agreement to power the Resorts World Bet's online sports book operation in New York State. As early presented by Johnny, this strategic B2B agreement should be viewed as an accretive and valuable partnership for the company, but not indicative of a larger B2B strategy of PointsBet. Cash outflows during the quarter included cost of sales of $44.8 million, which grew on the previous
