數獨的感覺太像了功課嗎?嘗試號碼蛇:更多的樂趣,無頭痛
Number Snake is a fun number game where you fill in numbers sequentially until you have completed the puzzle. Every adjacent box has to have a number that is one greater or one less than a box next to it (no diagonals). This game is similar to Numbrix in the parade magazine, but with unlimited puzzles.
