A screwy tile for Zack Freedman's Hextraction. This tile is optionally a combo tile or a mechanical tile. Play the halves together or separate.

If played together, it's a mechanical tile with moving parts! You may unscrew the bolt to any position you like. The bolt half has a tab that blocks travel in the nut half, so you can create a variety of paths. The threads will be a little loose, so don't expect it to stay where you left it.

If played separately, it's a combo piece. Follow normal combo rules about tile placement and destruction.
