In the Plusword word puzzle game, players must use words to fill up a grid resembling a crossword. The game can be played daily in challenge mode, in which players get one chance to solve the problem, or unlimited mode, in which players can play as often as they like.
When compared to ordinary crosswords, Plusword puzzles are more challenging. Finding the right words that fit the grid in the game requires using hints. The hints may pertain to a particular subject or may just be common knowledge.
