The singular for dice is die. The statement "when a die falls into the world, he can't see the number that makes his fate, he has to sort out his number on the way, collecting hints by the reaction of the others" is correct for a single object, however English uses the concept of objects that do not have gender. A die is an object, a thing. To be grammatically correct the statement would be " When a die falls into the world, it can't see the number that makes its fate. It has to sort out its number on the way, collecting hints from the reaction of others."

The context of the statement makes it clearer that the reference is in regards to an object, however as NITRO777 indicated, a die can also refer to a mechanism for machining objects.

Using the plural of die (dice) further refines the context to something particular.

"Lost Dice" has a cool sound to it.



@Error014 - you're right. I hear it all the time. Another one is irregardless when people really mean regardless.
