If there are fewer students than planned, the groups of 4 can be reduced. Just text us for a refund. If there are more students then booked, please reorder via e-mail.

To ensure that you have availabilities on your preferred date, you should book as soon as possible. You can also secure a date for the next 14 days & book later (no payment required yet). It is always possible to cancel free of charge after booking.

If there is a short rain shower, simply start later or take a break. If the weather is very bad, you can cancel or reschedule the booking free of charge.

Teachers receive start codes for each group. They hand them out to the groups. The groups enter the codes & start within an interval of 1 minute.

Only one smartphone is required per group. Should a battery run out, you can continue playing with the same code on another mobile phone.

A game requires a maximum of 10MB. That's less than spending 10 minutes on Instagram or watching a YouTube video.

No, the city rally runs via the smartphone browser (Chrome, Safari, etc.). So there is no need to download an app & it works on all smartphones.

No, you can freely choose the start time on the day of booking. This allows you to remain flexible. If there are a lot of classes or large groups (+100) playing on the same day, we will contact you individually to ensure that there is no time overlap.
