Corner Castle Turret Fortress
Let's build a cool mini-castle turret that stands by itself in a room corner!

Stick it to
Do the Stick Test
Gently try one tile on the corner edge. If it sticks, congratulations, your wall has bonus play architecture.
Safety: Test gently first. Not all corners are magnetic, and paint may mark if pieces slide.

Parent note: Test gently first. Not all corners are magnetic, and paint may mark if pieces slide. Keep the build low.

If it falls off
Make sure all the pieces are connected into a strong 3D shape, not just leaning, or use a wider base.
Make it easier
Build a short, simple square tower with just a few layers and a roof.
Make it bigger
Add a second tower next to it and connect them with more tiles to make a bigger fort!
Chaos upgrade
Build a ramp up to your turret, or a drawbridge out its door!
