ristikkäisiin
Ristikkäisiin is a Finnish term that translates to "crosswords" in English. It refers to word-puzzle games where empty squares are to be filled with letters, according to given clues, to form words. The words are arranged in intersecting columns and rows. The game is played on a grid, typically black and white squares, where black squares separate words and white squares are to be filled. Clues are provided in numerical order, corresponding to the starting square of each word, and are divided into "across" (vaakasuoraan) and "down" (pystysuoraan) categories.
The popularity of ristikkäiset in Finland is significant, with numerous newspapers and magazines featuring them regularly.
