While the contents of watch.log may be difficult to read manually, it can be analyzed using generative AI tools to gain deeper insights into the match.[/p][p]The AI in Battle Hanafuda never “cheats”.[/p][p]By “cheating,” we mean referencing hidden information such as the opponent’s hand or unseen cards in the draw pile.[/p][p]Instead, the AI makes decisions based purely on prediction and probability, and the reasoning behind those decisions is recorded in watch.log.[/p][p][/p][hr][/hr][h3]■ Hard Mode (In Development)[/h3][p]Hard Mode, which allows players to battle the Hard AI, is currently still under development.[/p][p]The current Hard AI is still evolving, and the development team is continuing to refine it with the goal of creating the strongest video-game Hanafuda AI.[/p][p]As a reference, when running a simulation of 1,000 games (12,000 rounds) between Normal and Hard AI, the current Hard AI achieves a win rate of approximately 36%.[/p][p]We will continue releasing updates whenever improved algorithms demonstrate clear performance gains, and Hard Mode will be officially implemented once the AI reaches the desired level of strength.[/p][p][/p][hr][/hr][h3]■ Steam Achievements and Leaderboards[/h3][p]The Early Access version introduces Steam Achievements and Leaderboards, which were restricted in the demo.[/p][p]Leaderboards can be viewed directly from within the game and display the top 100 scores.[/p][p]Score is calculated as the player’s final points minus the opponent’s (Normal AI) score, and may be negative.[/p][p]You can also view a simple match log for each leaderboard score, showing how that score was achieved.[/p]
