Kotoba no Puzzle: Mojipittan

Mojipittan is similar in play to the word game Scrabble. Taking turns against the computer or a human opponent, the player uses tiles with hiragana to build words, eventually building upon their opponent's tiles with words of their own. Unlike Scrabble, however, each player may place only one tile per turn as opposed to multiple tiles in the former. Tiles must be placed next to any other tile on the board, space permitting, but at least one word must be formed with each tile placed; as long as these conditions are met, a tile may be placed anywhere on the board, even if not all of the other tiles a new tile is connected to form new words.
