How to Play Honkaku Hanafuda GB
Quick start
Choose a game and Free Match, read the rules and play an introductory hand. Move to the win-through mode after you can follow the scoring.
Controls
D-pad selects cards and commands, A confirms and B returns where offered. Read the chosen game's legal-move and scoring prompts; the rules differ among the three card competitions.
Honkaku Hanafuda GB — About this game
Start with one ruleset and inspect the hand before confirming a card. Flower-card matching and Oicho-Kabu's totals ask for different decisions, so reread the mode rather than assuming every game scores the same way. A free match gives room to compare the result of a choice.
