How much do text messages cost?

On average, it costs 6 cents to send a text message from European phone numbers to our Dutch number. It’s 10 cents from most phone numbers outside of Europe. For our trails, you’ll send approximately 15 messages, which equals 90 cents (from European phone numbers) to 1,5 euros (phone numbers outside of Europe) per trail.

When playing a trail via our web app, you need to use your phone provider’s data. Prices differ per provider.

When can I play Secret City Trails?
You can play within two months of signing up. On the day that you play, start the trail within the time window indicated on the trail’s dedicated page. If the trail states, start between 11:00 and 14:00, you need to send the ‘start message’ after 11:00 and before 14:00.

All of our trails can be played every day of the week unless stated otherwise on the page of the specific trail.

If we play with multiple teams, will they follow each other?
Teams usually separate quickly as people solve clues at their own pace, however we do recommend starting a trail at 10-minute intervals if you want to be certain you won’t follow each other.

Are you paid by the cafes and shops along the trail?
We are not paid by any of the spots along the trail – we simply think they are great and want you to discover them too!

If playing via text message, what number do I send ‘PLAY’ too?
Once you’ve signed up you will receive a welcome message. This is the number you can send the ‘start’ message to, to start playing the trail.

Our Dutch virtual number is+31642814056 and our Slovak virtual number is +421902022078.

How long does it take to receive the next clue, or a hint?
You should receive replies within 10-30 seconds. If your mobile phone reception is poor it may take a little longer.
