orange is a free puzzle game designed to test the player's logic in a variety of different ways. The objective might sound simple at first: the player has to turn the entire screen orange. However, completing this goal is easier said than done.

The app is perfectly suited to those who want a puzzle game beyond the countless clones of Candy Crush Saga or Tetris. This is a rare puzzle game in which no two levels are the same.

Turn the screen orange

orange gives the player a series of numbered puzzles. In each one, the screen consists of a mixture of shapes in various colors. The player's job is to ensure that only orange shapes remain. How this is done will vary with each level, and every puzzle has its own rules.

Can you work it out?

The game opens with a very basic tutorial puzzle — all you need to do is repeatedly press the screen. After this, orange becomes a matter of figuring out each level's unique rules. One puzzle might involve rotating shapes, while another has an element of timing, as you need to dodge a moving block.

The next level's always a surprise

As you play through orange, you'll be treated to one surprise after another. One puzzle involves dragging a dark hole around the screen so that white objects fall down. Another one requires you to bounce a basketball. Even the easier puzzles are fun.

A treat for puzzle fans

While the simple graphics are nothing special, puzzle fans of all ages should find something to enjoy in orange. The numerous logic tests offer educational fun for children and taxing brainteasers for adults. The catchy but mellow soundtrack helps enhance the quirky, laid-back mood of the game. The only downside is getting stuck on a puzzle.
