Duel Box - Challenge

Seven classic two-player games in one app. Play across a table on a single phone, against the computer, or on two phones over Bluetooth — with no internet connection, no account, and no server in between. THREE WAYS TO PLAY • Pass and play: two people, one phone. It tells you when to hand it over. • Play the computer: three difficulty levels in every game. Easy is beatable by anyone; hard is a real opponent that searches ahead, plays the chain game, or in Tic-Tac-Toe simply cannot be beaten. • Two devices: find a friend nearby over Bluetooth and Wi-Fi and play on your own screens. NO INTERNET, NO SERVER Two-device play uses a direct Bluetooth and Wi-Fi link between the two phones. Nothing goes through the internet. Walk out of range mid-match and the game pauses instead of forfeiting. Come back and it picks up exactly where it stopped, with nothing lost. ALSO • English, Deutsch, Español and Türkçe, switchable in the app. • Light and dark themes, or follow your system setting. • Sound and vibration, each with its own switch.
