Here’s a fun game you can play with friends.

It’s based on the Australian 4-digit postcode system, and gives you a way of superficially rating people that you meet using a couple of key criteria — a useful kind of secret language if you’re with friends who know the code.

• The first number is how you rate the guy’s face, on a scale of 1–9 — one being low and nine being high.
• The second number is would you sleep with the guy — it’s binary, either 0 for No or 1 for Yes. Assuming that we lived in a world where that was a realistic possibility.
• The third number is how you rate the guy’s body — on a scale of 1–9.
• The fourth number is would you have a relationship with the guy — binary again, either 0 for No or 1 for Yes. Again, assuming that we lived in a world where that was a realistic possibility.

To give some context to the relationship question, this doesn’t have to mean that you’re going to marry them, but something along the lines of — would you give up your summer to be with this person. If you live in London, where summer is a treasured and much-anticipated season, it’s quite a big deal to commit to spending your summer months with just one guy.

Here’s some examples, and the ratings I’d give them:

Gus Kenworthy

• 8190

Tom Daley

• 8180

Godfrey Gao

• 9191

Russell Tovey

• 7181

Anderson Cooper

• 7161

Ricky Martin

• 8170

Eli Lieb

• 8171

Eliad Cohen

• 9190

Don Lemon

• 7171

This could keep me entertained for hours…

Full disclosure — this game was taught to me by my friend Ming.
