impulsestation.ch is free, with no account required, and will stay that way. A donation is never necessary to use the site — but if the tools or the escape game were useful to you and you'd like to give a hand, this is the place.
Donations cover the site's hosting costs and the time spent developing new tools and new adventures for the escape game — whatever the amount, every donation is sincerely appreciated.
Secure payment via Stripe — card, TWINT, and other common Swiss payment methods accepted.
