House Design: Match 3 is a puzzle game in which the main character, Lisa, asks the player to help her decorate her new home. The only way for the player to access home renovation and decorative elements is by playing match-3 games. They earn coins from the games to pay to access floors, walls, ceilings, windows, rugs, furniture, plants and other decorative items for various rooms. When they have enough coins, they receive three upgrade options per type.
Every match-3 game features targets the player must meet to win the game. For example, they might need to remove a specific number of certain types of gemstones or other objects, such as pipes arranged to create jails around some gemstones and sealed or open boxes. They collect these targets by forming rows and columns of three or more matching gems. They can also reach the targets using boosters, such as bombs, hammers and rockets, that remove less or more than three objects at a time.
House Design: Match 3 offers the player several ways to earn additional coins, pink gemstones and boosters. They can play a free spin wheel every few hours, receive daily and task-related rewards or earn multipliers by watching advertisements. They can create boosters during games by forming lines of more than three objects. They can also combine two existing boosters to create more powerful ones.
