3D Color Place：3D Sudoku

The rule is the same as “Number Place”, so that the same color is not arranged in each row, column, block (3x3).
It is no longer possible to solve with only one face, and mutual faces can be solved by mutually solving surrounding cells that are shared with the side faces.
The game screen is displayed in 3D, and the answer is advanced while looking at not only the front but also the side cells.
In “Number Place” so far, it can be solved by row, column, block (3x3), but in “3D Color Place”, it may not be solved unless the opposite column and block (3x3) are confirmed.
It is different from the previous "Number Place".
Please read the in-app help (especially "Basic rules of 3D Color Place" and "Advanced rules for 3D Color Place") once before playing.
