How to jump
A number jumps as many squares as it says, across or up and down. A 1 reaches its neighbour, a 3 reaches three squares away. It jumps over anything in between, but must land on another number.

The smaller is taken from the larger, and the rest stays where it landed. Equal numbers both vanish. When a number gets smaller, its jump gets shorter.

Every level can be solved. The wrong order can leave numbers that cannot reach each other. Undo freely and try another way.

Clear a level without undoing to earn three stars. One or two undos earn two, more earn one. Starting over counts as one undo.

About the name
Hiku (引く) is Japanese for “to pull”. It is also the word for minus: 5 引く 2 は 3 means “five minus two is three”.

The character 引 is made of 弓, a bow, and 丨, a line: a bowstring being drawn. It is the same arc you see when a number jumps.
