Num-Cro (Numbered Crossword)

This is basically a crossword app, but slight different from what you may know. There is no clue sentences. Instead, each block has a number and blocks that share the same number have the same letter in it.

Also, the letters that can be used for each quiz are limited, this limitation is also your clue.

Too much complicated words or minor words are not used. Most (if not all) of the words are words you know.

This is very simple, but should be fun. Enjoy your puzzle time.
