This is a puzzle called a Skeleton.
Place the specified words in the designated boxes, either up, down, left, or right.
It's like a crossword puzzle, where the words are predetermined.
There are daily problems and problems by genre, and currently around 4,900 problems are included.
As you solve problems, you'll unlock avatars, which you can share with everyone on Skeleton Road.
Solving problems every day could be a great way to train your brain. Aim to become a 10th-level Skeleton Puzzle Master!
We plan to update the site once a month (adding 30 new problems). (As of September 2018)
