Newborn Town's TopTop Launches AI-Powered 'Slap Showdown' Built on Viggle's Physics-Native JST World Model
A match every 9.5 minutes, by the company's own count
Mark
So what is Slap Showdown, in plain terms?
Mimi
A mini-game on TopTop where you upload a photo, get a 3D character in about 30 seconds, and fight other players with it. The character moves with physics-based responses to your taps and drags.
Mark
Why does the Viggle part matter?
Mimi
Their JST model is described as physics-native. It represents the 3D world as units with position, mass, material and motion, instead of guessing physics from pixels.
Luke
Described by whom, though? That's Viggle's own account, and the under-one-cent cost per scene is also theirs. Nothing here verifies it.
Mark
What about the player numbers? One person did 1,041 matches in 22 days.
Mimi
It's vivid. One Japanese player averaged a match every 9.5 minutes, and an Eastern European player did 735 in 11 days.
Luke
Two heavy users are anecdotes, and they were picked by the company. We don't know how many players there are, or how many stayed. The 97% completion rate has no baseline either.
Mark
And the "high spending potential" line?
Luke
That's a prediction, not revenue. No spending figures are given.
Mimi
Fair. What's confirmed is the launch in September, the markets named, and Newborn Town's investment in Viggle.
Mark
So the real test is what?
Luke
Whether players are still there after month one, and whether JST-3 delivers what it promises.
Il Polso
- A single Japanese player reportedly logged 151 matches in one day, a figure the platform is using to show how fast the game has caught on.
- Phone photos become physics-driven 3D fighters in about 30 seconds, a speed that makes the novelty spread quickly through social feeds.
- Every headline number, from the 97% completion rate to the 66.8 daily matches in Eastern Europe, rests on self-reported data with no outside check.
- Viggle claims its JST-2 model generates scenes for under one US cent, and it is already readying JST-3 as a broader simulator for games and robots.
- The real test is whether the first-month surge survives into the weeks ahead, and that remains unsettled.
In a quiet corner of the phone-in-hand era, a small game called Slap Showdown has arrived with a promise that a person's own photograph can become a physical, moving body inside a shared play space. Built by the social platform TopTop, operated by Newborn Town, on a physics-native model from Viggle, it turns a snapshot into a three-dimensional figure in about half a minute. The companies say players are taking to it eagerly, though the evidence so far comes from their own tallies, which the wider world cannot yet weigh. It is one more step in the long human effort to make digital play feel like it occupies real space, and whether that feeling endures is a question only time and independent eyes can settle.
A player in Japan opened Slap Showdown 1,041 times over 22 days, and at the peak finished 151 matches in a single day. Those numbers come from TopTop's own operations team, who offer them as proof of how deeply the game has taken hold. Averaged out, it works out to a match roughly every nine and a half minutes.
Slap Showdown is a 3D mini-game from TopTop, the game-oriented social platform run by Newborn Town, built with Viggle's Joint Space-Time model, known as JST. A player uploads a phone photo and receives a customized 3D character in around 30 seconds, whether an anime hero, a cyberpunk cyborg or a LEGO minifigure. The character then enters multiplayer battles, moving through press-and-hold and drag controls with physics-based responses. The companies argue this makes the AI character more than a skin, since it is wired into how the game is played.
Since launching in September, the game has found traction in Japan, among Spanish-speaking users in North America and across the Middle East. TopTop reports a 97% match completion rate and another standout player in Eastern Europe with 735 matches in 11 days. Every figure is self-reported, and no independent source has verified them. The strategy is clear: mini-games draw users in, while social features keep them and generate revenue.
Viggle, founded in 2022, builds physics-native world models and first gained notice through its Meme Maker tool. Its JST-2 model learns the structure and dynamics of 3D space directly, representing objects as atom-like units with position, material, mass and motion. Viggle claims scenes generate in seconds for less than one US cent, though these claims also remain unverified. Newborn Town is both partner and investor, and Viggle's next model, JST-3, is meant to become a full world simulator for games and robotics. For now, the open question is whether the month's engagement will last.
A player in Japan opened the mini-game Slap Showdown 1,041 times over 22 days, according to figures from the platform that runs it. At the peak, that player finished 151 matches in a single day. Averaged out, that is a match every 9.5 minutes. The numbers come from TopTop's own operations team, and they are the company's chosen illustration of how deeply the game has taken hold.
TopTop is the game-oriented social platform run by Newborn Town. It recently launched Slap Showdown, a 3D interactive mini-game built with Viggle, a company that specializes in physics-native world models. The game runs on Viggle's self-developed Joint Space-Time model, known as JST. Players upload a photo from their phone, and the system turns it into a customized 3D character in around 30 seconds. The examples given include an anime protagonist, a cyberpunk cyborg and a LEGO minifigure. The player then takes that character into multiplayer battles against other users.
The controls are press-and-hold, tap and drag, and the characters respond with physics-based movement. The point, as the companies frame it, is that the AI-generated character is more than a visual skin. It is wired directly into how the game plays.
Slap Showdown launched in September and is now available in multiple countries and regions. TopTop's operations team says it has drawn particular traction in Japan, among Spanish-speaking users in North America, and across the Middle East. In its first month, the team says, the game attracted a growing base of highly engaged players with high spending potential. It reports a 97% match completion rate and a game-start rate above the platform-wide average. A second player, in Eastern Europe, played 735 matches in 11 days, averaging 66.8 a day with a one-day high of 126. All of these figures are self-reported, and the source offers no independent check on them or on how many players sit behind them.
The strategy is spelled out plainly. For a platform driven by user-generated content, mini-games act as entry points and traffic drivers, while social features carry retention and monetization. Personalized avatars, TopTop argues, give users new ways to express themselves and share moments with friends. The operations team says future releases could extend AI-powered 3D generation beyond avatars to customized environments, and that existing games might be refreshed with new features. It also floats more immersive, face-to-face interaction in virtual spaces.
Viggle, founded in 2022, builds physics-native world foundation models. It first drew attention with Meme Maker, an AI video tool that animates static characters with specified movements. In August 2024 it raised USD 19 million in a Series A led by Andreessen Horowitz. On 19 October it fully launched JST-2, which it compares in significance to GPT-2's role for language models. Rather than inferring physical structure indirectly from pixels, JST-2 is built to learn the structure and dynamics of the 3D world directly. Its underlying representation uses units resembling digital atoms, each with a position in 3D space, properties such as material, color and mass, and information on how it moves and responds to forces.
Viggle says four years of research produced an integrated stack covering tokenization, architecture, data engine, pre-training and post-training. It claims JST-2 can generate a 3D scene in seconds at an inference cost below one US cent, and that the content can then be rendered locally without rerunning the model for every frame. Those cost and capability claims are the company's own and have not been independently verified.
Newborn Town is both partner and investor. It backs Viggle, along with other projects in world models, AI companionship, AI agents and AI interactive gaming, and says it applies AI across product development, recommendations, operations, safety and marketing. Viggle's next model, JST-3, is meant to become a comprehensive world simulator that could underpin game engines and train robots, learning physical rules from data rather than from developer-written code. The open question for Slap Showdown is whether engagement reported over one month holds up beyond it.
