A nice amusement park. It is possible to visit the park and pay only for the rides you want to do. A few of the smaller ones are free. The revolving tower has a nice view of Helsinki.
The wooden rollercoaster is one of the oldest still working in Europe and is worth the visit.
The VR coaster is short and the carts are not really big. 2 adults might have problems fitting.

Single ride tickets are not cheap either (9 euro) and it seems all attrications are 1 ticket. So the fun house is equally expensive as a rollercoaster which is a bit weird.
