You're addicted.

If you're seriously thinking about buying a Pokemon Go Plus, there are few other explanations.

It's a $35, £35 or AU$50 wearable pin that quietly alerts you to nearby Pokemon -- that way, you don't need to pull out your phone to play the uber-popular Pokemon Go game.

Like with the slot machine at a Vegas casino, all you're doing is repeatedly pushing that single button to capture Pokemon, collect items and advance in the game. Push, push, push.

Thing is, if you're a Pokemon Go addict, you like it that way.

What's a Pokemon Go addict?

Pokemon Go is not what it seems. While it might look like a cute pet simulator at first blush, you can't meaningfully advance in the game without harvesting every creature in your path. And the game is programmed specifically not to let you do that unless your phone is on, GPS is active, screen is on, locked to the game at all times. (You can't even answer an email without losing progress.)

It's easy to spot a Pokemon Go addict: They're the zombies with heads buried in phones with Pokemon Go always visible on the screen. Or telling other addicts how their phone's fully charged battery died at 2 p.m. because they couldn't stop playing.

The Pokemon Go Plus lets you pay to fix this broken state of affairs.

The basics

Pay $35, £35 or AU$50 assuming you can find one in stock. (Most stores sold out on Day 1.)

(There's a standard CR2032 button battery inside that should last 100 days, according to Nintendo -- but we only saw a month. In the US, replacements sell for $4 on Amazon for a pack of 10.)

Pin it to your person (it's pretty OK at hanging onto pockets and lapels, but it could definitely fall off thin jeans), or unscrew the back cover if you'd rather attach it to the included, kinda blah, wristband instead.

With those steps out of the way, you should now be able to play most of Pokemon Go just by pressing that button, whenever it lights up. You can leave your phone in your pocket, purse or backpack without fear -- or even use it for other things while you play.

There's a slight learning curve to understanding what the pin's light and vibrations are trying to tell you, but you'll pick it up pretty fast. Plus, here's a cheat sheet:
