yanaginagi re-implements Oink's 2018 release "TomaTomato" in which players must be able to recite tongue-twisters created from a stack of cards that show the parts of the game's title, such as "nagi", "ya", "yanagi", and "yanaginagi".
A player rolls a die showing how many tiles will be revealed on each player's turn, with the next player needing to recite the words on the card as if it was one long word. Play continues until a player is unable to properly finish the word, at which point the players collect some tiles from the string.
Collected tiles will be combined to earn points for each "yanagi" or "yanaginagi" possible. The player with the most points when the deck runs out wins.
There are also a few special tiles, such as one that reverses the order in which the tiles must be read and one that reads "komugi".
The art in the game is credited to the Japanese musician yanaginagi from whom the game gets its title.
