One floor. Four players. No hiding.
Players share the same physical floor — a real arena that scales to the room. Same room, same air, same gravity — only the slimes and Minion trails are digital.
A co-located mixed reality VE-Sport experience. Up to 4 players. One physical floor. Real bodies, growing trails of Minions — in an arena that scales to fit the room.

Spectator-ready External MR camera turns the match into a watchable broadcast in real time.
Sport, reborn as a spatial scramble.
Goo Goo Clash collapses the line between sport and game. You don't sit. You don't tap. You move — for real — and the system answers in mixed reality.
Real space. Digital slimes.
MR passthrough lets you see your opponents' real bodies and real eyes — overlaid with the food, Minions, and trails you'll have to read in motion.
Made to be played, not watched.
Virtual Environment Sport. You'll feel it in your legs the next morning. The arena rewards reflex, positioning, and footwork.
The match as a stage.
An external MR camera turns each match into a watchable broadcast — a clean external POV that makes the digital layer legible to crowds.
Three rules. That's the whole game.
Move, eat, grow.
Run on the real floor. Eat food to spawn Minions that trail behind you. The longer your chain, the more space you control.
Stop for three seconds — you die.
The arena punishes hesitation. There is no standing still, no safe corner. Keep moving, or get reset.
Wear the crown.
Whoever leads the score wears a crown floating above their slime — visible to every player and every spectator, all match long.
Peer reviewed. Conditionally accepted.
Five SIGGRAPH 2026 reviewers and the Immersive Pavilion committee weighed in. Verbatim pull quotes from the official review pass.
COMMITTEE"The committee was very impressed with the overall polish of the submission. From the video it looks very fun to play. It also does a good job of showing off what is possible with multiplayer AR experiences. Overall we felt this was a very solid submission."
REVIEWER 01"Untethered Mixed Reality multiplayer games aren't something you see often. The game looks really fun to play from the video. Having a simultaneous spectator view is a nice touch so the people watching can see what's going on as well."
REVIEWER 02"This feels like a solid and practical system that is already close to a deployable consumer experience. It seems well suited for events, public installations, or entertainment venues."
REVIEWER 03"Your approach to mitigating the isolating tendencies of traditional VR is perceptive, and I appreciate how the project leverages mixed reality to promote social interactions."
REVIEWER 04"Goo Goo Clash takes it to the next level by implementing a multiplayer MR experience with competitive gamified elements. I believe many attendees would like to play this game with their peers."
REVIEWER 05"A significant strength of the project is its accessibility — the system does not rely on handheld controllers or external physical base stations for tracking, leveraging standalone hardware instead."
A floor that scales to the space.
The arena is size-agnostic. One admin headset scans the room, drops a shared anchor, and players step in — and it scales with the space — from a tight two-player duel to a four-player free-for-all. The only real limit is networking. At SIGGRAPH it stages in under a day within the pavilion footprint.

GooGoo Master
Eat food to grow your Minion chain. Sub-frame networking keeps every position honest.
P2

RX
Drape Boundary
Soft drape fence frames safe play. Visible to spectators, friendly to falls.
Powered by Meta Quest 3.
Five headsets share one spatial anchor so every player sees the arena in exactly the same physical spot. Mixed reality passthrough keeps the real world visible — digital food, scoreboards, and opponents overlay the room.
A small crew, shipping in person.
Four contributors flying to Los Angeles for the on-site installation. Production, engineering, design, lead.

Built to travel. Staged in a day.
Goo Goo Clash is a turnkey installation. Tell us your floor size — we bring the headsets, the rubber arena, and the broadcast rig. Here's exactly what it takes to host it at your venue.
❄️
Indoor + air-con
Must be indoors; air-conditioned is ideal — in hot conditions the VR headsets overheat, risking mid-game shutdowns or hardware damage.
💡
Bright enough, not too dark
The area must be well-lit — the VR sensors and passthrough cameras rely on light for tracking. Too dark and they can't read movement.
📐
Flat, dry, non-slip floor
The floor must be flat and dry before the rubber mats go down — for the safety of players in VR and so the mats sit flush.
