About this game

8 classic games. Two phones. One Bluetooth tap. Offline multiplayer — no Wi-Fi needed.

Blue Duel is an offline multiplayer arcade — Chess, Checkers, Connect 4, Battleship, and more — for any two phones, paired directly over Bluetooth. Works on Android phones and tablets, and pairs with iPhone and iPad too.

== EIGHT GAMES, ONE BLUETOOTH PAIRING ==

• Chess — outmaneuver your opponent and checkmate the king
• Checkers — jump, crown, and clear the board
• Connect 4 — drop discs, claim four in a row
• Rock Paper Scissors — best of N, lightning quick
• Tic Tac Toe — the 3×3 classic, perfectly tuned
• Battleship — hide your fleet, hunt theirs across a 10×10 grid
• Gomoku — line up exactly five stones on a 15×15 board
• Liar's Dice — bid, bluff, and call your opponent's bluff

Quick rounds for a five-minute layover. Deep enough to fill the whole flight to Honolulu.

== BUILT FOR THE PLACES WI-FI ISN'T ==

Airplanes — works in airplane mode (Bluetooth stays on)
Road trips — backseat champion all the way through dead-zone country
Cruise ships — skip the $200 satellite plan
Camping nights — duel by the firelight, in the tent, deep in the woods
Hiking & backpacking — that scenic overlook with no signal? Doesn't matter
Subways, basements, ferries — the duel never drops
The couch — because a LAN party shouldn't need a router

If two devices are in the same room, Blue Duel works. That's it. Android pairs with Android, or with iPhone — the connection works the same either way.

== WHY FAMILIES LOVE IT ==

• No accounts, no sign-ups, no strangers — just you and the player next to you
• Family-friendly across all eight games — no violence, no scary themes, no chat with the outside world
• Kids and grandparents pick up the rules in seconds
• Quiet enough for the back seat, fun enough to upstage the seat-back screen
• Bite-sized rounds: perfect for "five more minutes before bedtime"

== ELEGANT BLUETOOTH PAIRING ==

Open the app on two phones. One taps Host, the other taps Join. They find each other automatically. Tap Invite, tap Accept, play. No PIN codes, no fiddling in the system Bluetooth settings, no QR codes. We built the entire networking stack from scratch so the connection survives screen sleeps, app backgrounds, and the occasional wandering toddler.

== DAILY TICKETS, BLUETOOTH MAGIC ==

Every game costs a small handful of free tickets that refill every day. Run low? Watch a quick rewarded ad — opt-in only, never interrupts a match.

Want to skip ads entirely? Pick up the Lifetime Pass: pay once, duel forever, ad-free always, with unlimited tickets so you and your duel partner can rematch as long as the boarding music plays. Launch pricing in effect.

== WHAT'S IN THE BOX ==

• Bluetooth Low Energy pairing, no Wi-Fi or cellular needed
• Phones and tablets supported
• Android & iPhone multiplayer: pair any two devices over Bluetooth
• Family-friendly content
• Built by a small studio that genuinely loves elegant networking
