## What is Star Core Duel?

Connect starlight. Capture the core.

Star Core Duel is a 6×6 strategy board game designed for Apple Watch. You play as O against an offline AI opponent. Win by lining up four pieces horizontally, vertically, or diagonally—or by bracketing and capturing two pairs of opposing pieces.

Fair two-round duels
Each duel has two rounds. Round 2 mirrors the same balanced opening and swaps who moves first. The total score across both rounds decides the winner.

Four AI levels
Choose Easy, Medium, or Hard. Win a complete duel at all three levels to unlock the hidden Extreme challenge. Each level uses a different balance of capture tactics, blocking, pressure, and deeper search.

Daily line training
Solve one classic four-in-a-row position each day. Every puzzle is solver-verified, and hints follow the AI's actual defense.

Made for your wrist
Tap any empty cell to move—no cursor and no confirmation step. The interface supports VoiceOver, Reduce Motion, Reduce Transparency, and Increased Contrast.

Private and offline
No account, ads, analytics, tracking, or network connection. Games, settings, training progress, and stats stay on your Apple Watch.

Features:
• 6×6 board with line-four and capture victories
• Balanced mirrored openings and two-round scoring
• Four offline AI difficulty levels
• 90 rotating daily training puzzles
• Automatic save and resume
• Duel, first-move, second-move, line, and core win stats
• Native Apple Watch controls and accessibility

Requires Apple Watch with watchOS 11 or later.Connect starlight. Capture the core.
