About

One Digit Field

Read full description

One Digit Field is a puzzle game where you put numbers one by one in a 9x9 square while thinking carefully. The rules of the game are very simple, and the goal is to put numbers in all the squares according to the following placement rules. ・ 1 to 9 are lined up in one vertical row ・ 1 to 9 are lined up in a horizontal row ・ 1 to 9 should be placed for each 3x3 block This rule is similar to the puzzle games SUDOKU and Number Place, which are popular all over the world, regardless of age or gender, so you may be familiar with it. As a developer, I also love SUDOKU, and I think it's a perfect game for a short wait, and I enjoy several apps of the same type. One Digit Field is developed with a focus on "playability" and "multiplay". Of course, regarding the quality of the problem, I think we have prepared a so-called "good question". There are 7 difficulty levels, and each level has 200 stages, so we have prepared a total of 1400 stages. Furthermore, you can add 100 stages for 1 dollar by In-App Purchase (Non-Consumable). In addition, there is a daily stage, so you can enjoy it forever. First of all, please enjoy this app, and discover the deep fun of SUDOKU. *The music playing in this app is the music published in "Music Atelier Amacha" (https://amachamusic.chagasi.com). *From version 1.1, the automatic deletion function for digit memos has been added. For example, if you enter "5" at 9 times and use them up, the digit memo of "5" left on the board is unnecessary and annoying, so you had to manually delete them one by one. The automatic deletion function for digit memos deletes digit memos that are no longer needed in such cases. *In-App Purchase Information You can add 100 stages for 1 dollar by In-App Purchase (Non-Consumable). *In-App Purchase Restoration When reinstalling this application, you can restore the above purchase by logging in with the same Apple ID as purchased and tap 'Restore Added Stages' at Setting view. *Notes of In-App Purchase In-app billing will be charged via iTunes account. *Privacy Policy and Terms of Use http://hrathnir.info/index.php/page/iPhoneAppSupport
