The game asks you to fill the Sudoku puzzle so that each row, each column and each of the nine 3x3 sub-board contains all numbers from 1 to 9. Few numbers are given and fixed beforehand. Sudoku game is suitable for everyone. It trains your logic thinking. If you are expert on Sudoku, you can still play the game for kill time or keep your brain active, etc.

**** Features of this Sudoku Game ****

- 500 distinct (non-transformable) Sudoku puzzles.

[A Sudoku puzzle can be equivalently transformed to another Sudoku puzzle by relabelling numbers, swapping rows/columns, etc. Any two of our 500 distinct Sudoku puzzles CANNOT be equivalently transformed to each other.]

- Each Sudoku puzzle has a unique solution.

- 5 different difficulty levels.

- Option for transform Sudoku puzzle.

[When turned on, every time you play the SAME Sudoku puzzle (one of the 500 distinct Sudoku puzzles), it will be equivalently transformed to a random one so that it looks like a new Sudoku puzzle (but indeed equivalent).]

- Lock action.

[For easy to repeat the same action, e.g. assign same numbers to different cells.]

- Unlimited Undo/Redo.

- Save and load Sudoku puzzles.

[You can save the incompleted game and continue later.]

[In this game, you can purchase more Sudoku puzzles, more save entries and even purchase for ad free. They can all be purchased by using only game coins!]

**** Ads policy ****

We have the following three types of ads.

- Banner ad:

An ad shows as a top bar.

When will banner ad be shown?

Always on top unless you are in ad free period. No banner ad will be shown during the ad free period.

- Interstitial ad:

An ad in full screen. It may just be an image or a few seconds (about 5 seconds) video (controlled by Google Admob).

When will Interstitial ad be shown?

When you are not in ad free period, an interstitial ad will only be shown when one of the following satisfied,

1. App open or switch back to the app.

2. One of the following actions happens AFTER 20 minutes from the last interstitial is shown.

[---- Navigations, pause/resume/save/load game, start a new Sudoku puzzle or on Sudoku puzzle completed. ----]

So, assuming no switch out and switch back to the app, no more than one interstitial ad will be shown within 20 minutes. Also, interstitial ad will not be shown when you are filling the sudoku board, because it will only be triggered by the aforementioned actions. No interstitial ad will be shown during the ad free period.

- Rewarded ad:

An ad in full screen. Normally, it is a video about 30 seconds.

When will rewarded ad be shown?

Up to you. Rewarded ad is for earning game coins. You can select whether to watch it for coins.

Be frank, developers need ads for revenue. We think that the above ads policy is appropriate. There are not many ads (unless you keep switch out and back. However, in this case, the ad should not annoying because you are just switched back). If you have better idea about the ads policy, you are welcome to suggest us. Hope you can enjoy this game!
