openjack is blackjack (21) with classic, familiar controls, rules, layout, and visuals. Set a bet from your bankroll, take the deal, then hit, stand, or double against the house. The dealer draws to 17, blackjack pays 3:2, ties push. No insurance, no split. The window resizes freely while the cards stay a fixed size.
openjack is a single-player game of blackjack. You bet from your bankroll and try to beat the dealer by drawing to a hand closer to 21 than theirs, without going over.
If you want to save a session, openjack records straight to an MP4, supersampled so the video is as crisp as the live game. Toggle it from the menu before you start.
