# What is a Dime Word™?

This puzzle is based off the What is a Word™ series started by JLee

If a word satisfies a certain property it is called a Dime Word™. Here are some examples:

What is the rule to tell whether a word is a Dime Word™ or not? Why is it called a Dime Word™?

(Note that each word can be tested for whether it is a Dime Word™ on its own, without looking at any of the other words in the list of examples. And hello from the Maths Stack.)

A Dime Word is

a playable character from a Riot Games video game.
PHOENIX, CYPHER, VIPER, RAZE, BREACH, SAGE are all agents in Valorant, and
KARMA, PANTHEON, TALON, KINDRED, RUMBLE, NAUTILUS are all champions in League of Legends.

And it's called a Dime Word because

Riot Games is a subsidiary of Tencent.

Incidentally,

there's also a relationship between the Not Dime words:
ECHO, THUNDERBIRD, VALKYRIE, ZERO, LESION, MAESTRO, PULSE, LION are operators in Rainbow Six Siege, and
ECHO (again!), REAPER, BASTION, SIGMA, MERCY are heroes in Overwatch.

• puzzle was too easy because all the words could directly be googled
