## What is Number Baseball Duel?

Number Baseball Duel is a code-breaking brain game, also known as Bulls and Cows. Crack a hidden number using only Strike and Ball clues. Take on the computer solo, pass one device back and forth with a friend, play online against friends and new opponents, or face a friend next to you on your own devices.

■ How to play
• The answer is 3 to 5  different digits from 0 to 9.
• Right digit, right spot: Strike
• Right digit, wrong spot: Ball
• No matching digits: Out
• Get every digit in the right spot: Home run!

■ Four modes
• Solo: Crack the number the computer hid in as few pitches as you can.
• Pass & Play: Take turns on one device to crack each other's number. 1P bats first (top of the inning) and 2P second (bottom). Even if 1P hits a home run, 2P still gets the bottom of the inning. If both do, it's a tie.
• Online Match: Invite a friend through Game Center or get matched with a new opponent, then take turns at bat. It's turn-based, so the match goes on even when you close the app, and you're notified when it's your turn. The rules are the same as Pass & Play, and each turn must be played within 72 hours.
• Local Match: Two devices in the same place connect directly over Wi-Fi. One player hosts a room and shows a room number, the other picks the same number from the list of nearby rooms. No sign-in needed, and the devices don't have to be on the same network. Just turn on Wi-Fi on both.

■ Fair online play
Your secret number is never sent to your opponent during the match. When it ends, both numbers are revealed and every call is checked automatically.

■ Highlights
• Choose 3, 4 or 5 digits to set the difficulty
• My Records: fewest and average pitches for each digit count, plus Pass & Play, Online Match and Local Match results
• Online Wins leaderboard on Game Center
• A ballpark scoreboard look, 8-bit sound effects and music, haptics
• Light and dark themes
• No sign-up. Solo, Pass & Play and Local Match work without the internet (Online Match needs Game Center)
• Available in English, Korean, Japanese and Traditional Chinese
