We’ve been playing educational iPad game Mystery Math Town with our six year-old for a couple of weeks, and really enjoying it. Now it’s available for iPhone too.

On both devices, it’s a maths-based game aimed at 6-12 year-olds, where they help a “friendly and curious little ghost” explore a mysterious town, collecting fireflies as they go.

The town is split into different houses, each with a certain number of fireflies to find. Children explore the houses by solving sums – addition, subtraction, multiplication and/or division – which let them go through doors, windows and shin up and down ladders to reach new rooms.

The game is very customisable: a simple checkbox system lets you set which kinds of sums are used, and how difficult they are. The sums are solved by stringing together numbers that are found dotted around each house, then dragging and dropping them into place.

Our son is fairly early in his maths life, but he’s been really keen on the app, asking to use it whenever the iPad is to hand. It’s good news that it’s on the iPhone too, although in an ideal world it wouldn’t be a separate app, but a Universal one working across all devices – and saving the child’s progress.

Still, we can recommend both. Mystery Math Town for iPhone costs £1.49 on the App Store, while the iPad version costs £1.99. Here’s our video of the latter so you can see it in action:
