Explosive 21 Card Game

Free · Designed for iPad. Not verified for macOS.

Make 21. Light the fuse. Turn clever card moves into explosive combos in Boom 21—a card puzzle with fiery effects and simple controls. Every card counts. Every column can go BOOM! Boom 21 combines card strategy with explosive puzzle action. Place cards across four dynamite columns, aim for 21, and plan your next move before the fuse runs out. PLAN YOUR MOVES See your current card and the cards coming next. Choose a column carefully to make room, build your score, and keep your run alive. MAKE 21 Complete a column with a total of 21 and watch it erupt in flames. Aces count as 1, and Jacks, Queens, and Kings count as 10. WATCH THE FUSE Keep an eye on active dynamite and your remaining lives. Each decision can open up a new opportunity—or put your run at risk. LEVEL UP Build progress, reach new levels, and restore your three lives when you advance. Challenge yourself to beat your best score. PLAY YOUR WAY Adjust sound effects, motion and screen shake, and haptic feedback. Choose English or Turkish, and enjoy clear menus and large, easy-to-tap controls. Your progress saves automatically, so you can return to your game later. Make 21. Plan the fuse.
