Sudoku Checker

Version 1.3.3 has the following modifications to 1.3.2. ・ The recognition sensitivity of the Sudoku technique called XY-Wing is increased. ・ The recognition sensitivity of the Sudoku technique called XYZ-Wing is increased. ・ We are increasing the recognition sensitivity of the Sudoku technique called the Hidden Triple. ・ We are increasing the recognition sensitivity of the Sudoku technique called skyscraper. ・ The recognition sensitivity of the Sudoku technique called swordfish is increased. Version 1.3.2 fixes the following bugs in 1.3.1. -Sometimes I couldn't recognize the Sudoku technique called X-Wing. -The X-Wing level and the Hidden Triples level are displayed in the difficulty nest display dialog. Version 1.3.1 fixes the following bugs in 1.3.0. -Sometimes it freezes while entering numerical values. Version 1.3.x has revised the calculation logic of the difficulty level. Previously (up to Version 1.2.x), the difficulty level was high when the number of hints was small, or the difficulty level was less than 300 even though advanced techniques were required. Therefore, the calculation logic is revised. The basic functions are the same as before. You can also call the calculation result of the past calculation logics.

Version 1.2.3 implements the following modifications to Version 1.2.2. -The re-verification result in the old difficulty calculation formula has been changed to be listed as "for Bigginer". There is no change in the difficulty calculation logic.

Version 1.2.2 implements the following modifications to Version 1.2.1. -Supports iOS 14 advertisement display.

Version 1.1 adds the following features: -The advertisement display has been revised to support iOS14. -Fixed the problem that the background color disappears when initializing in diagonal mode.

There are a few minor bugs in the decision logic that are fixed. At the same time, we are reviewing the “Difficulty level judgment logic” By selecting “Revalidate with old difficulty formula” in the difficulty level display dialog, you can see the old difficulty level.

The installation target version has been extended to iOS 9. The size of the input character is increased, and the character derived by it is reduced. When there are multiple solutions, the [Verify] function makes it easy to see the relevant places and possible numbers.
