Description by Kouji Mori (from the App Store)

Sudoku (Number Place) is a puzzle game played all over the world.

The rules are simple: Fill all cells in a vertical row, a horizontal column, and a 3x3 box with 9 different characters so that there are no duplicates.

In this application, instead of the usual Sudoku numbers, the nine Japanese hiragana characters "い(i)", "ろ(ro)", "は(ha)", "に(ni)", "ほ(ho)", "へ(he)", "と(to)", "ち(chi)", and "り(ri)" are used to play.

These characters are taken from Japanese Iroha-uta.

At first, you can play the Training stage and the Easy stage.

Unlocking unlocks all features.

- Normal stage
- Hard stage
- Expert Stage
- Daily mode

It is recommended for brain training, so please play it!
