How it works

How it works

This is how our mysterious birthday invitation works

Step 1

Choose your secret invitation:

Send the starting date, the first clue and a personal code via our mysterious card, or magic box. Nice twist: keep yourself secret, and reveal yourself on location or after some hints.


Box Experience


  • Secret invitation BOX
  • Lots of confetti
  • Hint reveal app for invitee
  • Shipping costs

Card Experience


  • Secret invitation CARD
  • Classic post card
  • Hint reveal app for invitee
  • Shipping costs

Step 2

Send hints about your birthday plan.

On your Hint page, build up the tension for the birthday one with self-created hints. Have him or her guess the sender, the outing, dress code, start location, and so on. You can schedule images, links and text that the invitee then scratches open.

Hints can be viewed via: android or: ios app, or via the Hintle website.

Step 3

Think of your outing

You want the lucky one to feel special thanks to your gift. Everything is good by putting the personal connection first. From a picnic, surprise party, great day trip, a special activity such as underwater hockey, to a home movie evening

A selection from our curated intense outings for an original birthday gift.

Mom could just bare the tension. She kept thinking about hints I gave. She loved my home-made wellness and hiking day as an outing a lot.

It was really nice. Especially because my boyfriend could not guess what we would do. And when the time came the planned comedy night was just perfect!

How do I know the surpriser knows me?
Good one. People at Hintle first check theirselves if you might know each other. If not we contact the surpriser. If you want to know for sure it is not your ex or weird colleagues, just send us your thoughts and we will double check it : ). 
I want to invite a large group, can you help me on-board them?
YAASS. so nice! And of course, if you are inviting over 20 people, send us an email and we will send you an empty .csv, so you can copy and paste your own database into it. 
Best time between invitation and 'the special day'?
We mostly advice a minimum of 2 to 3 weeks. The longer, the more anticipation. Shorter means less hype. It also depends on what you are planning. A spontaneous picnicking? Maybe a half year is a bit too far away. But for a wedding, it might be too early.
