The Mischief Within, Curiosity Cove, Mandai

Halloween at Mandai, with clues and stamps instead of chainsaws.

For families with primary-school children or younger, this is the Halloween outing to choose over anything with the word horror in it. The Mischief Within is a mission at Curiosity Cove, Mandai's indoor discovery attraction: children follow clues and complete challenges to help two characters, Al and Min, solve a mystery, collecting stamps on a mission card as they go. Mandai says there are seven to collect.

There are two ways to do it. Boo-tiful Day runs every day until 1 November, 10am to 5.30pm, and Mandai says the activities are included with Curiosity Cove admission, so it costs nothing extra if you were going anyway. Sundown is the after-dark version, 6.30pm to 9.30pm on selected nights, sold as its own ticket. The remaining Sundown nights are 23 to 25 October and 30 October to 1 November.

Our call: daytime is the better bet for under-sixes, who will be done long before 9.30pm, and it is the cheaper option because it rides on the admission you already have. Sundown suits older children who want the novelty of being at Mandai after dark on Halloween weekend. Crafts and candy bags are extra at S$6 each, which is worth knowing before you get to the counter with a six-year-old.

Mandai hasn't published an age range, and the admission price isn't on the event page, so check both on its online store before you book. If you are combining it with a park visit, do the mission first, while small legs are fresh, and keep the mission card somewhere safe: seven stamps is a lot to lose at the last one.
