メゾン・ド・カード (Maison de Card)

Knock twice. A millionaire-style puzzle game where you build your own house. The game consists of five types of cards, each distinguished only by color instead of numbers. When it's your turn, you use these cards to create a combination that is stronger than the one played previously. The way to create combinations is simple: Without changing the order of the cards in your hand, ① play one card, ② play multiple cards of the same color, or ③ play multiple cards of different colors. The cards you play become building blocks for your own house. Keeping them connected, you stack them on top of your house, like dropping blocks. The number of floors you build directly translates to your base score, so the primary goal of building a house is to build as high as possible.
