This system allows players to earn “Rank Cards” each time they clear a game-like mission.
As they collect cards — BRONZE, SILVER, GOLD, PLATINUM, and beyond — they can ultimately aim for the prestigious LEGEND rank.
Through this mechanism, HADO has successfully increased its player retention rate across Japan.

Missions That Make Players Want to Come Back

The key attraction of the Rank System lies in the physical reward players receive — an actual card — each time they complete a mission.
Players work through missions one after another to level up their cards.
Early missions are simple, such as “Win one match” or “Score three points.”
As players advance through the ranks, the challenges become tougher — “Win a tournament,” “Compete as a team” — naturally cultivating their skills and motivation.

When a player, especially a child, completes a mission and receives a new card, they experience the pure satisfaction of being the hero of their own game.
That moment of joy becomes a powerful motivation: “I want to get the next card!” — driving them to return and play again.

A “Real RPG” Experience for Parents and Children

The Rank System has been especially popular among elementary school children and their parents.
Children set their own goals and challenge themselves in HADO, while parents support and celebrate their progress.
HADO has become a shared source of fun and excitement within families.

For parents, HADO offers a safe and active experience where they can also engage with digital technology.
Collecting cards together and watching their child’s growth has become a new form of parent–child communication — an experience that connects both generations through play.

Rank Progression as a Gateway to Competition

At higher ranks, players are required to achieve results in official tournaments.
This encourages many children to take part in competitions, marking their first step into HADO as a true sport.

The Future of a “Sport You’ll Want to Keep Playing”

Through the fusion of sports and gaming, HADO is building a new sports culture centered around challenge, achievement, and growth.
The Rank System is one of the key ideas supporting that culture.

As HADO continues to expand across the world, this system — born in Japan — will serve as a model for sustaining player engagement and spreading the joy of “a sport you’ll want to keep playing.”
