Put a number on your GPU.

Your phone or computer does thirty seconds of real math. Our server checks the answer, ranks you against people with the same device, and pays you in NVIDIA stock.

Step 1 · The work
17.2Bsums

Your GPU multiplies two big grids of numbers, A and B. One round of that is 17.2 billion small sums, and your GPU does many rounds every second.

Step 2 · The answer
4.2Mnumbers

The result is a third grid, the answer. Every number in it is a whole number, so there is exactly one right answer.

Step 3 · The check
32checks

When you finish, our server picks 32 numbers from your answer at random and works them out itself.

Step 4 · The result
0mistakes

All 32 have to match. Then your speed counts, you get a rank, and you get paid in NVIDIA stock.

The test

Thirty seconds. Three rounds.

Round one and two measure speed at two levels of precision. Round three runs flat out to see if your device slows down when it heats up. Works in Chrome, Edge and Safari 26, on computers and phones.

Keep the page open until it finishes. Switching apps or tabs pauses the GPU and the run is dropped. Plugged in gives a cleaner number. Only your score and device model are published.

The wall

Every run that checks out adds a tile.

Each tile is one run that passed the server check, from anyone, anywhere. Sixty-four tiles fill a row.

    Phones race phones.

    You only compete with the same device as yours, so an old phone can still come first. Your best run is the one that counts.

    Coming next · Earn Mode

    Your computer sits unused for hours every day.

    Earn Mode will put that idle GPU to work while you're not using it. Whatever it earns gets turned into tokenized stocks you pick, and lands in your wallet.
