ただのナンプレ

Sudoku, reimagined with fish kanji.

Forget plain old "1, 2, 3." Solve puzzles using nine kanji characters for fish — from Tuna (鮪) to Sardine (鰯) — in our one-of-a-kind Fish Mode. Don't read Japanese? No problem: flip on furigana readings and breeze right through.

Prefer something a little more classic? Try Kanji Mode, solving with traditional Japanese numerals (壱, 弐, 参... up to 玖). Or stick with plain Arabic numerals for a relaxed, familiar game. Switch between all three anytime, right from the title screen.
