Battle Jack: Card Strategy Combat to 21 Points | Brain-Teasing Solitaire

Launch into Battle Jack's mind-bending strategy combat! Tap cards to build your attack force while keeping total points under 21 – hit exactly 21 to unleash maximum damage. But beware: Exceeding results in defense-only mode! Strategically eliminate opponent HP using smart card combinations and timely attacks. Pro Tip: Champion selection alters battle dynamics. Game ends when you deplete enemy’s health first – but go too high, you can’t counterattack!
