Bridge of Cards
A mobile physics puzzle where you drag playing cards past a table edge to maximize overhang without tipping the stack. A live centre-of-mass marker and exact tipping simulation show the theoretical maximum for the current card count, turning play into optimisation. Two variants (Classic single-wide, Counterbalance multi-wide), card counts 3-12, auto-solve reveal, and a shareable result card.
