Question: Upwords and Codenames are both types of what?

Context paragraphs:
Codenames (board game): Codenames is a 2015 board game designed by Vlaada Chvátil.  The game is typically for two teams of at least two players each, but can also be played by two or three players with just one person simply acting as the "Spymaster" (i.e. clue-giver) for the other one or two.  Rules for these variants are provided in the game instructions.

Upwords: Upwords (also branded as Scrabble Upwords in the United States and Canada, and Topwords Crucimaster, Betutorony, Palabras Arriba, Stapelwoord in other countries) is a board game invented by Elliot Rudell and originally published by the Milton Bradley Company, now a division of Hasbro.  The game remains under license to Hasbro by Rudell Design, LLC.  Upwords is similar to "Scrabble", or "Words With Friends", in that players build words using letter tiles on a gridded gameboard.  The point of difference is that in Upwords letters can be stacked on top of other letters already on the gameboard to create new words.  The higher the stack of letters, the more points are scored.  This typically makes words built in later turns of the game more valuable than earlier words, increasing play intensity and adding a level of strategy unique to Upwords.  The memorization of two-letter words is considered a useful skill in this game.
