To roll a D%, you simply spin the D10 twice. D10 ring shows numbers from 0 to 9.
- The first spin represents the tens digit (e.g. 7 = 70)
- The second spin represents the ones digit (e.g. 5 = 5)
- Add them together to get your D% result (for example, 70 + 5 = 75)
- If you roll two zeros (0 and 0), that’s counted as 100.

GELOHO Dice is made from premium zinc alloy and stainless steel, built to withstand everything from -10°C winters to 80°C heat. It's also rust-resistant in environments with humidity up to 80% RH.

To clean it, simply wipe the surface with a damp cloth. Just be sure not to rinse it with water—moisture trapped inside the bearing may lead to rust over time and could affect its performance.

You don’t need to open it or do any kind of maintenance. Prophecy Dice runs smoothly without any oil or lubrication, and its internal spring-and-gear system is built to the same durability standards as high-end mechanical watches.

The sealed design isn’t just for looks — it also helps protect the mechanism from drops, bumps, and everyday wear, so you can trust it to hold up game after game.

Yes— GELOHO Dice Spinner is built to last.

Its outer shell is made from solid zinc alloy, while the internal gear system is crafted from high-grade stainless steel. Each unit is CNC-machined for smooth, precise movement.

We also apply multi-layer electroplating with a clear protective coating to resist wear, corrosion, and fading.

Like a mechanical watch, it’s tough—but not unbreakable. For everyday carry, we recommend using a Slip Case or pouch to keep it looking pristine.

The Dice spins fast—really fast. Once you press the button, the internal number plates spin at over 500 RPM. For context, the human eye can’t track anything over 60 RPM, so after the spin starts, all you see is a blur.

Could someone “train” to control the outcome? In theory, yes—but only if you could time your button press down to the millisecond. Realistically, you’d need to hit a window of around 3 milliseconds to consistently influence a result. Most people have a reaction time of 200–250 ms, and even elite athletes rarely go below 150 ms—still far from what's needed.

We also follow classic dice-balancing principles. For example, the D20 ring is laid out so opposite sides always add up to 21—just like a standard D20—ensuring proper balance and randomness.

So no need to worry: every spin is as fair as a real dice roll—just way cooler to watch.
