BIOSTACK
Human vs Biohybrid Intelligence
BioStack is a game and scientific experiment in early alpha. In it humans compete against a living biohybrid processor: real neurons, cultured in a dish, wired with brain machine interfaces, and silicon processors.
Every session you play feeds real research into how living neural cultures can be used for computation. This alpha is intended to allow a limited number of supporters to join us in advancing the state of biocomputation. Your feedback shapes what we build.
Free to play
How It Works
BioStack is free to play. Our living biohybrid processor has one seat, and it's online on a limited basis: when it's free, it's first come, first served.

Play When the Seat's Open
Free play is first come, first served, up to 30 minutes a turn. Each new game or continue uses 1 credit.
Or Reserve a Guaranteed Hour
$5 for a full hour with the seat to yourself: unlimited games and continues, no credits needed.
Reserve a Guaranteed Hour
Skip the wait: the seat is yours for the whole hour, with unlimited games and continues and no credits needed. Times are first come, first served.

Reserved hours are $5, charged when you reserve. Cancel at least 24 hours before your start time for a full refund; times starting within 24 hours can't be refunded. All times are Eastern Time.
Meet Your Opponent
Your opponent is a biohybrid processor. It combines a living culture of real biological neurons, grown in a dish and kept alive on our hardware, with silicon processing, and plays against you in real time. When the culture is in the loop, its activity helps choose your opponent's moves; when it isn't available, the game switches automatically to a simulation.
The Intactis BPU
The Biohybrid Processing Unit (BPU) houses the live neural culture, the well-plate at left, alongside the electronics that read its activity and stimulate it. When the culture is in the loop, its activity helps choose your opponent's moves.
- Real living neurons, cultured and maintained on-site
- Read & stimulated through a microelectrode array
- Its activity feeds the AI when the culture is in the loop
Support Us
Intactis is a small team of scientists, engineers, and developers building biohybrid computers. We are in an AI energy crisis. The brain is one of the most energy-efficient computers known. We are building biohybrid processors as an alternative to the dominant silicon paradigm. Your support helps us develop the technology, fund the buildout, and bring new experiences to you the player.
Support the Build-OutContributions are separate from game credits. To buy credits, use the game or your account page.
Intactis Bio Corp is a for-profit company. Contributions are voluntary, are not tax-deductible, and fund development of additional biocompute gaming capacity.
Why can't I play right now?
BioStack runs on one seat connected to a living culture, so it's online on a limited basis. If the status above says someone is playing or a reserved hour is running, check back soon. If BioStack is offline, you can ask us to bring it online, or reserve a guaranteed hour.
How long is a free-play turn?
Up to 30 minutes. It ends sooner if you stop playing for a few minutes or a reserved hour is about to start, and we warn you 5 minutes before. Then the seat opens for the next player.
What does a $5 reserved hour get me?
The seat for a full hour: nobody else can play, and games and continues are unlimited with no credits needed. Your opponent combines our living neural culture with silicon processing. If the culture isn't available, the game switches automatically to a simulation so your hour keeps running (see the Liability Waiver).
When am I charged?
Only when you reserve an hour ($5) or buy credits ($1 each, from the game or your account page). Entering your credit card information doesn't charge it, and you always see the exact amount and confirm before any charge. Credits don't expire.
What do I need to play?
A computer with a physical keyboard and an up-to-date browser (Google Chrome on Windows works best). BioStack can't be played on phones or tablets.
Can I cancel a reserved hour?
Yes, until your play link is sent, about an hour before your start time. Cancel at least 24 hours before and we refund your $5; closer than that, the $5 isn't refundable. If we have to cancel, we refund you in full automatically.
What if something goes wrong on your side?
If a problem on our side stops a reserved hour (the game won't load, or it's interrupted for more than 15 minutes), we'll refund your $5.00 or move you to a new time. If it cuts short a free-play game, we'll return the credit. Email press@intactis.bio within 7 days.
