## What is Expanding Tic Tac Toe?

9×16 is a tic-tac-toe game that grows with you. Win and the board expands; lose and it shrinks. Win streaks compound. Master a 3×3 grid and the next round becomes 5×5. Climb all the way to 15×15.

FREE MODES
• Single Player — you vs AI, expanding boards, escalating difficulty
• Time Attack — 90-second score chase, combo × board size

PRO MODES ($1.99/MONTH)
• Hot Seat — two players, one device
• Blitz — 3s or 5s per move vs AI
• Defender — don't let AI win; draws count as victory
• Survival — streak chase, escalating boards, one loss ends the run
• Online — play remotely with friends, 30s per turn, QR-code invites

DESIGN
Hand-tuned monospace typography, calm dark and light themes, minimalist board, pleasing animations. No ads, no tracking beyond crash diagnostics.
