Fill The Region is a free puzzle game for mobile devices from developer MondayOFF. It is a color puzzler that has players fill in drawing with specific shades to complete each level. The main catch is that no two same-colored spaces can sit next to each other.

Drawing from the same concept as coloring apps like Coloring Book for Me & Mandala or Recolor - Coloring Book, Fill The Region takes the simple yet relaxing appeal of coloring books and turns it into a fun and charming puzzle game that anyone can play and enjoy.

Coloring the blanks

Coloring books are fun activities for children that help stimulate their creativity. Through the years, though, their appeal has extended to adults due to their relaxing aspect, going so far as creating a subgenre aptly called adult coloring books and subsequent apps for smartphones and tablets. Fill The Region is what would happen if this popular concept is used to create a puzzle game.

In this game, there are drawings that you will color using reds, blues, yellows, and greens. The catch, though, is that the same color can't be next to each other as you fill them in. Start a new game, and the sketch will be front and center, while the row below lets you quickly switch between colors. Controls are simple and intuitive, with taps and swiping.

There are multiple levels to go through, and each one offers shapes and objects of ever-growing complexity. Things start off slow but it's deceptively simple, offering a surprising challenge in later stages. One area where the game could use improvements is its design. The art style and presentation are too simplistic. It could use some more design flair to make the experience more immersive.

Simple yet fun

All in all, Fill The Region is just a nice and relaxing coloring puzzle game that you should check out. It's easy to learn, the controls are simple, and it can get surprisingly challenging. While the overall presentation will be too plain for some, it doesn't detract from the fun you'll be having while playing it. Give this one a try now.
