Halloween crosswords is a word-based game featuring various clues. Begin by reading the clue, then select the numbered block where you wish to input your answer. To fill in an answer for an across clue, click once on the corresponding block number; for a down clue, click twice. Pay attention to the position of the green arrow next to the clue to confirm your selection is correct. The game includes three levels: two focused on Halloween themes and the final one centered around movie thrillers. It is compatible with mobile devices and tablets, but navigation through the crossword blocks requires the use of the arrows.
