Suitable for group outings, varied movement games. The first time I played these games, especially mountain climbing. I bought unlimited voucher but actually playing for 1 hour is very tired. If you do watch American Ninja Warriors, the game here is a bit similar but easier (of course). Each person must buy 1 pair of non-slip socks (50k) that can be used many times. Next time you play, just bring your non-slip socks. Will come back and play mountain climbing!
