Blue Duel: Bluetooth Games

Two phones. Any phones. Bluetooth.

Blue Duel is the head-to-head mini-game arcade that works over Bluetooth with no Wi-Fi, no cellular, no accounts, and no internet of any kind.

== THREE WAYS TO PLAY ==

• Bluetooth Battle — two separate phones
• Pass & Play — hotseat on one device
• Solo — play against the computer, or settle in with Solitaire

== TEN GAMES ==

• Othello — flip your opponent's discs and finish with the most, a.k.a. Reversi
• Chess — outmaneuver your opponent and checkmate the king
• Checkers — jump, crown, and clear the board (solo vs the computer, too)
• Solitaire — Klondike solo (Casual or Classic), or race a friend over Bluetooth: Double Solitaire (shared foundations) or Mirror Solitaire (same winnable shuffle, separate boards)
• Rock Paper Scissors — best of N, lightning quick
• Tic Tac Toe — the 3×3 classic, perfectly tuned
• Connect 4 — drop discs, claim four in a row (solo vs the computer, too)
• Battleship — hide your fleet, hunt theirs across a 10×10 grid
• Liar's Dice — bid, bluff, and call your opponent's bluff (solo vs the computer, too)
• Gomoku — line up exactly five stones on a 15×15 board

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 phones are in the same room, Blue Duel shines — the full ten-game Bluetooth Battle catalog opens up. Just one phone? Hand it back and forth for Pass & Play, take on the computer solo in every head-to-head game, or settle in with Solitaire. (Tent, RV, lunar shuttle, Mars colony rec room — same rules apply.)

== WHY FAMILIES LOVE IT ==

• No accounts, no sign-ups, no strangers — just you and the player next to you (or the AI on your screen)
• Family-friendly across all ten 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. They find each other automatically. Tap Invite, tap Accept, play. No PIN codes, no fiddling in iOS 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 ==

Bluetooth Battle 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. Solo Klondike and Pass & Play never use tickets.

Want to skip ads entirely? Grab the Lifetime Pass — pay once, duel forever, ad-free always. It also unlocks unlimited tickets, so you can rematch as long as the boarding music plays.

== WHAT'S IN THE BOX ==

• Ten games, three modes — Bluetooth-paired with a second phone, pass & play on one, solo against the AI in every head-to-head game, or Solitaire on your own
• Cross-platform multiplayer: pair with friends on other mobile operating systems over Bluetooth
• Bluetooth Low Energy pairing, no Wi-Fi or cellular needed
• iPhone and iPad supported
• Family-friendly content, rated 4+
