Here are a few games that I find particularly helpful in building strong relationships.

Truth or Dare Cards
This game asks questions like "What kind of music would you choose to make me feel romantic?" or "Name the most important moment in our relationship." These questions can help partners understand each other better and reveal their feelings.

Carcassonne is a strategy game that requires players to work as a team and make decisions together. This game helps to learn communication and interaction between partners.

Monopoly is a classic game that helps you learn financial literacy and plan. It can also be a good way for partners to get to know each other better, such as how they react to winning and losing.

Scottland Yard is a puzzle game that requires players to think and work together to solve problems. This game helps to develop teamwork skills and learn how to make decisions together.

Alias is a game where players have to explain words without using forbidden words. This game helps develop communication and interaction skills between partners.

All in all, board games are a great way for a couple to spend time together, strengthen their bond, and learn to understand each other better. I hope that my recommendations will help you choose games that will not only be fun, but also beneficial for your relationship.
