House Painter, also known as House Paint, is a sliding-tile, world-building game. The player paints houses and other structures using a square paint-soaked sponge with round corners. Every time they successfully paint a building, they receive cash. They then use the money to build the structure in a community that's set up as a grid with green, empty squares separated by gray streets. They can also upgrade the structures to create better ones. Their primary goal is to create an entire city (My City) via these processes as they unlock new levels.
The game is an example of sliding-tile mechanics because the sponge acts like a tile that the player directs along straight paths on the sides of each building. They can't stop the slide until the sponge comes into contact with a non-paintable object, such as one or more sections of wood siding, metal air vents, electric boxes, horizontal and vertical windows or trimmed hedges. They can direct the sponge up, down, left and right to cover unpainted walls.
House Paint gives them a variety of color options, including blue, green, pink and purple. That said, they can only use the paint color preselected by the game. The good news is that they're not penalized for painting over a previously painted area to achieve their goal. They merely need to make certain that they paint each wall thoroughly.
