Sudoku Painter

What is this game about?
This is a fun variation on the traditional Sudoku game. We have noticed that some people respond better to colors than numbers. It is a single-player game with a goal to fill the field with colors without duplicating same colors in the same row, column or group (square).

How do I control the game?
You play by clicking the empty cells and opening the color selection. Enter one of the colors on the palette. If there is the same color in this row, your cell will be crossed out - that means a mistake. If there is the same color in this column, or inside the main group as this cell, it will also be crossed out.

How do I win?
The goal is simple, manage to place fill all empty slots with colors and you will win.

Gameplay tips:
1) Consider that fulfilling one square field immediately will end up invalidating the rest, try not focus on just one. Instead distribute the missing colors one at a time throughout the entirety of the board;
2) Sudoku games are very hard depending on the density of the board. Go for smaller boards first to get used to the gameplay;
