Play Webgrid

At Neuralink, we use a game called Webgrid to test how precisely you can control a computer.

The goal of the game is to click targets on a grid as fast as possible while minimizing misclicks. Your score, measured in bits per second (BPS), is derived from net correct targets selected per minute (NTPM) and grid size.

Our first clinical trial participant achieved a score of 9.51 BPS controlling his computer with his brain.

How well can you do?
