Seashells

You're combing the beach for shells to sell to Sally, and every flip is a bet against your own nerve. Flip cards one at a time, but your net can only hold so many shells. Stop to take all the shells of exactly one color. If you end up with the exact number of shells your net can hold, you'll earn a pearl that Sally loves for your nerve. Push too far and you go home empty-handed, but your net gets a little bigger for next time. Turn your shells into goal cards for points, and let your hidden shell tile score bonus points for collecting the right shells.
