Roblox (RBLX) reported bookings that grew more than analysts forecast last quarter as the online gaming company tweaked its platform to increase user engagement and continued to benefit from being added to Sony PlayStation consoles last year.

The stock rose 16% at the market open.

Bookings, a closely watched measure of sales, rose by 34% in the third quarter to $1.13 billion, compared with the $1.01 billion consensus estimate as compiled by Bloomberg. Roblox raised its fourth quarter bookings forecast to a range of $1.34 billion to $1.36 billion and boosted the upper end of its full-year prediction to a range of $4.34 billion to $4.37 billion.

In the third quarter, adjusted EBITDA, including the effect of deferred revenue, was $223.4 million, versus the $141 million predicted by analysts.

Daily active users rose 27% over the prior year period to 88.9 million, spending a total of 20.7 billion hours on the Roblox platform.

The DAU metric recently came under fire from short-seller Hindenburg Research in early October, which asserted in a report that Roblox inflates user numbers by counting multiple accounts tied to single users.

“Over the last six months, we’ve made a number of really significant improvements to the platform. First and foremost is our search and discovery algorithms,” CFO Mike Guthrie said in a Zoom interview with Yahoo Finance.

Also contributing to the boost in bookings, he said, were more games added and more updates to existing games: “We’re seeing more new experiences breaking into the top 100 and potentially becoming viral. And we’ve really noticed that some of our more established developers are doing more significant updates more frequently.”

Excluding the effect of the PlayStation console, which Guthrie said peaked in the third quarter, bookings rose 28%.

Both in the quarterly release and interview with Yahoo Finance, Guthrie said the company is clear that daily active users (DAUs) can include multiple accounts from single players and pushed back against Hindenburg’s claims. “DAUs are a measurement of the accounts, and we’re clear on this,” he said. “We can have a user that has an avatar that is a baseball player and one that’s a fashion model. It’s totally normal and natural on the platform.”

Investors seemed relatively unfazed by Hindenburg’s allegations. Roblox shares fell 2% on Oct. 8, the day the report was released; since then, they’ve risen by more than 3% through Wednesday’s close. That said, they’ve fallen nearly 6% this year, in part because of weak bookings forecasts in past quarters.
