Blue Duel

Eight head‑to‑head games over Bluetooth, plus Solitaire when you’re flying solo. No Wi‑Fi. No cellular. Just you and the player next to you.

iPhone · iPad · Android

Bluetooth, not the cloud

Phones pair directly. Play on the couch, on a plane, or anywhere the network won’t follow.

Short rounds, long matches

Tic Tac Toe before your coffee gets cold, or a full game of Chess over breakfast. Nine classics — your pick.

Built for two — or one

Designed from the ground up for one‑on‑one matches between two people in the same room. Solo? Settle in with Solitaire.

Nine classic games, one tap away

Pair your phones, pick a game, go. From a five‑minute round of Tic Tac Toe to a full game of Chess between two players in the same room — or settle in with a quiet round of Solitaire on your own.

A ‘2 Phones, No Internet — Instant Bluetooth Battles’ headline above two iPhones linked by a glowing Bluetooth bolt. One screen shows a Tic Tac Toe O glyph, the other an X. A row of game tiles beneath — Checkers, Chess, Liar's Dice, Gomoku — plus a ‘… and more’ chip teases the rest of the catalog.

‘Your Turn, Their Move — Same Room. Same Game.’ Two iPhones side by side, both showing the same Checkers position from opposite seats. A Bluetooth pairing graphic links the two devices at the bottom.

A ‘Play Your Way’ headline above the Blue Duel home screen, showing three mode cards: Bluetooth Battle (two nearby devices, no Wi‑Fi needed), Solo (sharpen your strategy), and Pass & Play (one device, two players). A Game Library row sits underneath.

A ‘9 Classic Games’ headline above the game library grid: Solitaire, Chess, Checkers, Liar's Dice, Gomoku, Connect 4, Tic Tac Toe, Battleship — each with its own illustrated tile.

A Chess game mid‑match under a ‘Head‑to‑Head’ headline. Black and white pieces are deployed across the board, with an ‘Opponent's turn’ indicator and a live‑play replay scrubber below.

A ‘Solo Classic’ headline above a Solitaire game on a green felt background. Foundations on the left wait for the four Aces; a draw pile sits on the right; seven tableau columns cascade down the middle in alternating red and black runs.

A ‘Pair and Play’ headline above a Liar's Dice round in progress. The phone is angled with a second phone partially visible — together with the next image it shows two phones side by side in a Bluetooth match.

Liar's Dice mid‑bid under a ‘Bid And Bluff’ headline. Hidden cup dice in the corner, opponent thinking message at the bottom. A second phone is partially visible on the left, continuing the Bluetooth pair from the previous image.

A Gomoku board mid‑game under a ‘Deep Strategy’ headline, with black and white stones forming the early shape of a five‑in‑a‑row battle.

A Tic Tac Toe round‑over screen under a ‘Quick Rematch’ headline. A glowing line crosses three X's; a Rematch button sits below the result, ready for the next round.
