Yellow

Yellow is a puzzle game with 50 levels. Each one is played on a fixed, single screen. Puzzles require the player to turn the entire screen yellow, usually by getting rid of all black sections. This is done by experimenting to figure out the logic for a specific puzzle. There are often elements that can be manipulated such as circles. Actions such as pointing and holding, rotating or a combination of different elements also often yield results.

The game is free-to-play. When stuck there is a light bulb in the corner that can be clicked to receive a hint after watching an advertisement. There are multiple hints per level. On mobile a premium unlock is available to view the hints without ads. The browser version does not have ads and is limited to 25 levels.
