This game is a combination of Sevens and Daifugo.
The player who gets rid of all their cards wins, but to do so they must meet two conditions.
① Their cards must touch an existing ladder card on the table above, below, left, or right.
② Their set of cards must be stronger than the set played by the previous player.
The goal is to play all of your cards as quickly as possible while fulfilling these conditions.
Demonstrate that you are the best at climbing up and down the ladder.
