Build hiragana words on the board with the tiles in your hand, crossword-style, against the computer. Words read left to right or right to left, top to bottom or bottom to top.
- Drag tiles from your hand onto the board (or tap a tile, then a square) to make a word, in one row or one column, joined to what is already there. Every run of two or more tiles you touch must be a word.
- Select a tile and press ゛ Dakuten, ゜ Handakuten or Small to play か as が, は as ぱ, や as ゃ, つ as っ.
- Press Done when your word is complete. Points are the tile values of every word you made or extended, plus the bonus number of each square you placed a tile on. A word that is not in the dictionary reduces 5 points, and you get a chance to try again.
- Pass if you have nothing. Fresh tile set swaps your hand for new tiles and skips your turn. The game ends when both players pass in a row, or the bag is empty and a hand runs out. The highest score wins.
- Only use single words. Expressions such as 気にする are not allowed, nor are katakana loanwords.
