Google’s Playground targets the adult players Roblox is trying to reach

Roblox says adults account for about 80% of a $200 billion gaming market, while its U.S. adult daily users grew 32%. Google launched Playground for U.S. adults, with no creator payout announced.

Roblox tells investors that adults over 18 account for roughly 80% of a global gaming market worth about $200 billion a year. Reaching older audiences is central to its goal of capturing 10% of that market. Based on age-checked users, Roblox estimates that its U.S. adult daily users are growing 32% year on year, compared with 10% growth in global daily users. Among U.S. users aged 18 to 34, growth is 42%.

On 7 October, Google launched Playground, an experimental platform for creating, playing and sharing custom games from a prompt. It is open "for users in the U.S. (18+)". Google and Unity are now competing for the audience Roblox says it needs to reach. Roblox's U.S. adult daily-user growth will show whether Playground is gaining ground. The number of games created will not, and neither will this year's bookings decline: Roblox attributes that decline to younger players, and it began before Playground launched.

Both companies are moving toward that audience. Roblox's Build already supports prompt-to-game creation. It began as a public alpha in New Zealand for users aged 9 and over, with a free base tier and paid tiers for power users. Roblox is also adding 2D, single-player, offline and turn-based play. The company says 2D accounts for about one third of the U.S. gaming market and that the expansion "positions us to capture a greater share of the O18 cohort". Playground runs in a browser on a phone or laptop. Its gallery ranks games by player ratings and activity, and Google One sells tiers of creation access. The joint Google and Unity release says Unity Spark will arrive later this year with "high-fidelity 3D capabilities" and the Unity runtime. Google says Spark is still being tested, with a closed beta to come.

Roblox is not short of games. In the second quarter, its top 10 games accounted for about 20% of hours, down from 30% three years earlier. Hours spent in experiences outside the top 10 grew by 25%. Paying users are the scarce input. Roblox's 10-Q says about 1.6 million of its 123 million daily users pay on an average day. Each payer generates $10.42 in daily bookings, compared with $0.14 per daily user overall. Roblox estimates that U.S. adults monetise at a rate more than 50% higher than younger users, and it has raised the Developer Exchange rate on their in-game spending. Creators received $363 million through the programme in the second quarter, about 23% of bookings, according to Roblox's supplemental materials.

Google's launch post says nothing about paying creators. Playground gives builders distribution through its gallery, and the joint release says Google will highlight standout creations across its network. But the membership product sold to players has no stated route for creator payouts. Google brings reach, Unity brings an engine, and Playground already offers leaderboards and multiplayer in some genres, narrowing the product gap Roblox holders might hope would remain. Roblox still has 27 million average monthly payers and a Developer Exchange payout that Google has not matched. Roblox has just raised that rate for the adult spending Google is pursuing. A studio earning money on Roblox can publish on Playground to reach Google surfaces without giving up its existing income. It cannot move that income to Google, where no revenue share has been announced.

The bookings decline is easy to misread. Roblox guides third-quarter bookings of $1,576 million to $1,653 million, 14% to 18% below the $1.92 billion booked a year earlier. The letter blames weaker monetisation per hour of play, "most notably with younger cohorts in the U.S. and Canada". It also points to a change in the Recommended for You feature and the disabling of cross-experience game passes. The quarter ended on 30 September, a week before Playground existed.

Bookings were already falling before Google arrived, and Roblox points to younger users as the cause. Treating the decline as an early Google effect misreads both companies and obscures the contest for adult users, which the headline bookings figure does not isolate. Roblox has published no history for the adult cohort beyond its current growth rates, so that disclosure carries unusual weight in each shareholder letter.

The fourth quarter will show whether the problem among younger users deepens or stabilises. Bookings rose 21% from the third to the fourth quarter in 2024 and 16% in 2025. Applying the same seasonal lift to this year's guidance gives $1.8 billion to $2.0 billion, 10% to 18% below the $2.22 billion booked in the fourth quarter of 2025. Guidance in that range would suggest the recommendation and game pass changes are still costing Roblox what they did in the summer. A forecast above $2.0 billion would suggest it has recovered some younger-user spending without help from adults. The fourth-quarter report will be the first to include a period when Playground existed; last year's report came on 5 February. Roblox's adult-user growth rate will be the measure of Google's impact.

Roblox reported last year's third quarter on 30 October 2025 and has not yet announced a date for this year's report. That letter will show no Google effect, but it will reflect Roblox's own product decisions. At the guided range, the recommendation change and the end of cross-experience game passes leave third-quarter bookings $269 million to $346 million below a year earlier. At the second quarter's 23% payout rate, that gap means about $63 million to $81 million less reaching creators in one quarter. Those creators are the people Google is courting with a gallery and reach, but no cheque.
