Your questions, answered.

How difficult is it to build the mazes?

Intrism Pro is a challenging build with a 7/10 difficulty. Intrism Mini is simpler with a 5/10 difficulty. Neither one requires any tools or glue.

All of our products are designed to be easier to build than to solve so that the fun isn't over too quickly!

How difficult is it to solve the mazes?

Solving Intrism Pro is very challenging with a 10/10 difficulty. Intrism Mini is less challenging with a 7/10 difficulty.

Both Intrism Pro and Mini require lots of dexterity to solve. For something a bit easier, try out Intrism Level One.

What are the differences between the two series?

The Original series (Pro & Mini) require the assembly guide, unlike Intrism Level One where it is optional (for a little added difficulty).

Additionally, the marble can fall off of the track in our Original series mazes, whereas in Level One it cannot.

What happens if the marble falls off the track?

Intrism Pro and Mini are designed so that if the marble falls off the track, it can be reset to the starting line with just a few twists of the marble maze.

Intrism Mini has two additonal starting points that place the marble at level 2 and level 3.

Can the pieces be assembled in multiple ways?

No, the pieces only go together in one way to create the final marble mazes. You do have the option of using our video walkthroughs instead of or to supplement the printed assembly guide.

Can I color the wood to customize them?

Absolutely! Color them to your heart's content. We recommend using acrylic markers rather than paint, and are working on themes for purchase as well.

Level One themes are available now.

Would these be good gifts to give?
