| An original 9x9 number puzzle that uses arrows as clues to solve. Recommended for those who like real puzzles that are solved by theory. You can check if the numbers you entered are correct. (the number of times is limited) You can turn on/off the check function that points out input errors. You can save two pieces of input data. * At level 6, please think without using the "confirmation function" and "check function". |
