• Everyone in the family pays a day pass, adults included, and kids under 15 train alongside an adult
• Wristband grading on weekends for courses 1 to 4, Saturdays and Sundays 10am-4pm; the upper-floor courses need booking, and grading pauses over the summer holidays
• Pool included in the day pass, though the pool closes for maintenance all of July

Ninja World is the indoor ninja warrior hall at the Sports Club Vallentuna gym, which has more than 150 padded obstacles in all. Six courses run from easy to very hard, and kids earn a colored wristband for each one they clear. Smaller kids get a 10-obstacle parkour course and a Baby Park of soft blocks. Next door, OCR Heaven adds military-style obstacles, treadmills and a bouldering cave.
