House Paint 2 is a continuation of the original House Painter (House Paint) sliding-tile game. That said, it doesn't offer a player much to do beyond painting empty spaces between wide sections of siding on the walls of each building. The game also doesn't offer cash earnings or community-building goals. Instead, it provides a peaceful, repetitive, hypercasual experience. It features extremely basic graphics with block-world hedge elements, smaller unpainted wall zones, and paint stamp blocks with pointed corners rather than sponges with rounded corners.
The player's painting goal is the same as in the first game. They must paint any area on a wall that's unpainted and not non-paintable objects, such as wood siding sections, hedges and mail boxes. They perform this task with slide-tile play, which means that they direct the paint block straight up, down, left or right in an unpainted zone along different paths. They can't stop the slide of the paint block until it reaches a non-paintable object.
As with the first game, House Paint 2 doesn't issue any sort of penalty to the player for sliding the block back over an area they've already covered with paint.
