Yes—but only in a very limited laboratory demonstration. In a University of Washington experiment reported on December 5, 2016, five people navigated simple two-dimensional mazes after a magnetic coil delivered flashes of light directly to the visual parts of their brains. They made the correct move about 92% of the time with the brain-stimulation cue, compared with 15% in control mazes without it.
This was not a headset that read thoughts and translated them into any game command. It was a proof of concept showing that externally supplied, binary information can guide behavior without ordinary visual, auditory or tactile signals.

What the University of Washington experiment demonstrated
The study used 21 simple mazes. At each decision point, participants had to choose between moving forward and moving down. A transcranial magnetic stimulation (TMS) coil positioned near the back of the skull sometimes produced a phosphene—a perceived blob or bar of light. The presence or absence of that sensation encoded which move to make.

With stimulation providing the cue, participants averaged 92% correct moves. In control mazes without that guidance, accuracy was 15%. Those figures describe this specific five-person, binary maze experiment; they do not measure performance in commercial games or prove that the method works for every player.

How a mind-controlled game worked here
- Maze software selected the next move. Each junction required one of two possible actions.
- The TMS coil delivered a pulse. The pulse could create a phosphene in the participant’s visual field.
- The sensation carried one bit of information. A phosphene present or absent signaled the permitted direction.
- The participant acted on the cue. The person still made the physical game input; the brain stimulation supplied the missing sensory instruction.
The important technical direction was encoding information into the brain. Many brain-computer-interface projects instead try to decode signals from the brain to infer a user’s intended movement. This UW system did not decode arbitrary thoughts, speech or game commands.
What “using only your mind” does—and does not—mean
What it did mean
- The maze direction was communicated without a screen, sound or touch cue.
- The participants’ brains learned to use an artificial sensation they had not previously encountered as useful information.
- The task showed that direct stimulation can augment a simple human-computer interaction.
What it did not mean
- It was not unrestricted thought-to-controller gaming.
- It did not let players issue a rich set of commands such as aiming, jumping and speaking through thoughts alone.
- It did not eliminate physical equipment or establish a plug-and-play consumer product.
Is this technology available to buy?
No equivalent consumer system was established by the demonstration. The TMS hardware was bulky laboratory equipment, not something designed to be carried or safely operated at home. Andrea Stocco, a UW assistant professor and co-author, said, “The technology is not there yet — the tool we use to stimulate the brain is a bulky piece of equipment that you wouldn’t carry around with you.”
Rank #2
The equipment also requires specialist operation and safety oversight. Generic EEG headsets, VR headsets and so-called brain-control controllers may be related to the broader brain-computer-interface field, but they are not the stimulation method or game demonstrated by UW.

Rajesh Rao, the senior author, framed the central question as whether the brain could use artificial information delivered directly to it to navigate a virtual world or perform a useful task. The maze result answered yes for this narrow, binary setting.
Rank #3
Darby Losey, the lead author, described the goal as giving humans “a sixth sense.” In practical terms, that could mean adding a warning, direction or other low-bandwidth signal when a conventional sense is unavailable or occupied.
Possible future applications
The UW team discussed longer-term uses in virtual reality, gaming and assistance for people with sensory deficits. A direct neural cue could, in principle, supplement a VR display or provide information that a user cannot receive reliably through sight, hearing or touch.
Rank #4
Those possibilities remain different from a finished product. A useful future system would need portable hardware, a larger and richer command vocabulary, reliable stimulation across users, fast setup, strong safety controls and compatibility with ordinary games.
How to judge future “mind-controlled gaming” claims
| Question | Why it matters |
|---|---|
| Is the system stimulating the brain or decoding brain signals? | Stimulation sends information in; decoding infers the player’s intention. They are different technologies. |
| How many commands are supported? | A binary cue for two maze choices is far less capable than continuous movement, aiming or voice-like control. |
| Is it invasive? | Implanted and noninvasive systems have different medical, practical and regulatory requirements. |
| How portable is the hardware? | A laboratory coil cannot be treated as a living-room accessory. |
| What feedback does the player receive? | Visual, audio, haptic and direct neural feedback affect how independently a user can play. |
| What accuracy and setup time are documented? | Results should identify the participants, task, conditions and training rather than imply universal performance. |
| Does it work with ordinary games? | A custom maze demo does not demonstrate compatibility with commercial game software. |
What happened to the commercialization effort?
The UW release said team members and outside partners co-founded Neubay to commercialize neuroscience and artificial-intelligence techniques for virtual reality and gaming. The linked domain is now parked, so the company’s current status and any affiliate or successor program are not verified. That uncertainty does not change what the 2016 experiment itself established.

The practical answer for players today
You cannot buy a verified version of this exact UW system and play modern games with thoughts alone. The experiment is best understood as an early human-computer-interaction demonstration: a TMS coil supplied one bit of artificial sensory information, and people used it to solve a very simple maze. It showed a promising principle, not a finished gaming platform.
