A modern, playful icebreaker game built with Astro and React. Tic2Talk puts a unique twist on the classic Tic Tac Toe - each player can only have 3 pieces on the board at a time, with the oldest piece being automatically removed when placing a fourth. Perfect as a fun conversation starter between two people!

• Unique 3-Piece Rule: Each player can only have 3 pieces on the board - oldest piece gets removed automatically
• Visual Indicators: Pulsing animation shows which piece will be removed next
• Smooth Animations: Confetti celebration on wins, smooth piece placement and removal
• Win Sound Effect: Embedded audio plays on victory

• Dark/Light Mode: System-aware theme with manual toggle
• Fully Responsive: Optimized for mobile and desktop
• Beautiful Animations: Fade-in effects, zoom animations, and smooth transitions
• Custom Icons: Animated X and O icons with SVG stroke animations

• Rigged Mode: X can never win - only O (Pink) wins (perfect for pranks!)
• Phone Number Collection: Optionally ask winner for their phone number
• Name Input: Optionally collect winner's name
• No Skip Button: Force phone number entry (no escape route 😄)
• Settings Persistence: All preferences saved in localStorage

• Installable: Full Progressive Web App support for iOS and Android
• Offline Mode: Works completely offline after first visit
• Add to Home Screen: Native install prompts for mobile devices
• Network-First Strategy: Always tries to load fresh content when online
• Service Worker: Smart caching with automatic update detection

• vCard Generation: Creates proper contact cards from collected phone numbers
• iOS Optimized: Direct contact card display on iPhone
