The map pack includes 2 themes: My World and Treasure Trail.
It also includes extra coding cards and a Storybook, with simple activities to try with kids. The map pieces and coding cards are made of strong compressed cardboard, and have a special print to interact with mTiny and the Tap Pen Controller.
The treasure trail cards turned our after-school routine into a little adventure hunt, and my son actually asks to play it. The storybook activities are simple enough that he can lead them himself.
The My World map is the one my daughter keeps coming back to, and the little storybook gives us a script when I'm too tired to invent activities. Cards are sturdy enough that they've survived being shoved in a drawer between sessions.
The Treasure Trail map got my 5-year-old actually sitting still for twenty minutes, which never happens. The extra coding cards slot right into what we already had, so no new pieces to figure out. Map pieces feel sturdy enough to survive a toddler too.
