## What is Ultimate Tic Tac Toe?

The classic 3×3 tic-tac-toe you know, evolved into an "ultimate" battle of wits played across nine boards. Simple to pick up, surprisingly deep to master — a fresh take on strategy games.

■ What is Ultimate Tic Tac Toe?
The cell you choose decides which board your opponent must play next. A single move can shape the game several turns ahead, making every read-the-opponent decision matter. Easy to learn, endlessly deep to master — perfect for a quick match on the go or a long session at home.

■ Two game modes
• Ultimate Tic Tac Toe — the main mode: nine small boards nested in one big grid. Win three small boards in a row to win the game.
• Classic — the timeless 3×3, for a quick match or a rules refresher.

■ Full range of match types
• vs CPU — Easy / Normal / Hard, plus a hidden difficulty that appears once you keep beating Hard. Can you reach it?
• 2 Players — face off on one device with a friend or family member. No connection needed, anytime, anywhere.
• Online Match — find an opponent through matchmaking for a real match, with a per-move time limit that keeps things tense. Chase a new win streak.
• Play with a Friend — send an invite code to challenge a friend online directly.

■ Built to help you improve
• Winning-move hint — a gentle nudge toward the best move when you're stuck.
• Undo — recover from a misclick with a safety net.
• Choose who goes first — start the match on your own terms.
• Achievements — track milestones like your first win, win streaks, and clearing every difficulty.

■ Make it yours
• Multiple board themes — Neon, Washi, Forest, and more, to match your mood.
• Automatic light/dark mode — easy on the eyes, day or night.

■ Play offline
Solo and Classic modes work completely without a connection — a quick brain workout anywhere, signal or not.
