About this game

Only numbers are written next to the grid. If you figure out which square to color just by looking at those numbers, a hidden picture reveals itself. Nonoday is that kind of logic puzzle.

The rules are summarized in a single sentence. The number at the beginning of a row indicates the length of consecutive squares in that row. If it says "3 1," it means three squares are connected, and there is one square after leaving at least one space. Since the horizontal and vertical numbers describe each other, once you confirm one square, the one next to it is confirmed accordingly, and the board is filled in this chain.

Guessing is not an option. Every puzzle in Nonoday is presented only after it has been confirmed that there is only one correct answer. Any square can be reached solely through logic, and conversely, cannot be reached without logic. Therefore, when you finish the board, you are left with the feeling of having solved it, rather than feeling lucky.

Seventy stages are prepared. The first ten boards are 5×5 in size, so a few minutes is enough to get familiar with the rules and controls. From the eleventh level, the board expands to 10×10, marking the beginning of serious deduction, and from the forty-first level, a large 15×15 board awaits. However, it is not just the size that has increased. Because clues have been conserved even within the same size, the later 10×10 boards become completely different problems from the earlier ones.

The controls allow you to drag your finger to color multiple squares at once.

Coloring and marking with an X are switched with a single button. If you mark a square you are unsure about with an X, solve another row first, and then return, the answer will often be revealed in the meantime.

It is okay to get it wrong. Each board provides three leeway, and if you are stuck, you can use a hint to open a square and get a clue. Your progress is saved automatically, so you can pick up a board on the subway and simply turn it off when you get off. No internet connection, registration, or login is required. It starts immediately upon turning it on.

If you are someone who wants to use your brain briefly during your commute, or if you have enjoyed Sudoku or crosswords, you will pass comfortably.
