About the game

Kumimoji, "letters put together" in Japanese, is a word game where you build a single crossword from every tile in the bag. You start with a hand of seven or eleven tiles and lay them on the grid, in a connected shape, so that every run of two or more letters across or down is a real word. When your hand is empty and the grid is valid you draw the next tiles; the game ends when the last tile from the bag has been used, and the clock tells you how fast you did it.

Tiles can be English letters or Japanese kana. Some tiles are wild stars that stand for any letter, and you choose how many ("Most", "Some" or "None"). The Diagonals option also counts words that run diagonally. Every game is dealt from a seed, so Today's game gives everybody the same bag, and Copy link lets you share a game you want a friend to try.

Playing it here

Click Play and pick English or Kana tiles, a hand of 7 or 11, and how many wild tiles you want; New game deals a bag. Tap a tile in your hand, then a square on the grid (the first word goes anywhere, the rest must connect to it). The line under the grid shows the words the game does not accept, such as "Not words: ic", so you can fix the grid. Draw takes the next tiles once your hand is empty and the grid is valid, Trade for three swaps a stuck tile for three new ones, Lift all takes the tiles back into your hand and Sort tidies the hand. "Save and load" keeps a game as text that you can paste back later. The timer runs from your first move.

A few things worth knowing

Build short words first. Two- and three-letter words are easy to extend and give you many places to attach.

Keep a wild tile for last. A star can rescue a hand that is stuck on awkward letters.

Mind the plurals. The English list is a full word list, so plurals and common inflections are accepted.
