Ion: A Compound Building Game*

Players select from a range of ion and noble gas cards to form sets of compounds. Each player starts with eight cards, choosing one and passing the rest. Players can pair their chosen card with another element card or play it alone, aiming to form ionic bonds later. Points are awarded for building specific compounds and collecting noble gases. After three rounds, players tally their scores, subtracting points for used action tokens, and the player with the highest score wins.
