Love Letter Lab: free Valentine's game for heartfelt notes

What is Love Letter Lab?

Six short notes for six people in your life: a partner of six years, someone you've dated for three weeks, a best friend on Galentine's, a grandparent, a flatmate, a work friend. Build each note from a warm opening, a true detail and a sign-off, and land its warmth in that person's sweet spot.

Love Letter Lab is a free Valentine's Day writing game. Six people, six short notes: a partner of six years, someone you've dated for three weeks, a best friend on Galentine's, a grandparent, a stepdad, a flatmate, a work friend. Each note is built from three cards: a warm opening, a specific detail and a sign-off.

Every card carries a warmth of one to three hearts, and every person has a sweet spot. Big feelings fit a partner of years and rush a new date; romantic words confuse a friend, a grandparent or a colleague. The detail has to be true, too: each person's card says what really happened, and every answer explains why it works or doesn't.

How to play

Read the person

Who they are, the occasion, and what's really true about you two.

Three cards

Pick a warm opening, a specific detail and a sign-off. 100 for spot on, 40 for OK.

Mind the warmth

Each card has 1 to 3 hearts. Land the whole note in the sweet spot for +50.

Three lives

A miss (wrong memory, wrong tone, a complaint, a request) costs a life.

Scoring

100 points for each spot-on card, 40 for an OK one.

+50 when the finished note's warmth lands in the person's sweet spot.

A miss (wrong memory, wrong tone, a complaint or a request) scores nothing and costs one of 3 lives.

What it trains

Specific detail

Swap "you're always there for me" for one real, true moment.

Matching the relationship

Pitch the warmth to a partner, a new date, a friend, family or a colleague.

Kind framing

Keep a note a gift: no complaints, requests or unasked-for advice.

Strategy and tips

Name one real moment

"You're always there for me" is kind. "You stayed on the phone all night before my test" is unforgettable.

Check the memory

A wrong detail hurts more than no detail. If you're unsure, leave it out.

Match the warmth

Big words for a partner of years, a lighter touch for week three, friend-words for friends.

Keep it a gift

No complaints, no requests, no advice nobody asked for.

Sign it like you

A sign-off that sounds like you, and your name, beats a formal ending.

Why play Love Letter Lab?

A good note is short, specific and pitched to the person. Practising with made-up people makes it easier to write the real card, whoever it's for: a partner, a friend, family or a colleague.
