If you are doing corny games anyway...you could fold up little pieces of paper and put them inside balloons. Have guests pop the balloons and the one with the flower sticker on the paper gets the flowers. Totally stole this from another mom's post about birthday parties, thought it sounded like great fun! Or you could do the Victorian thing with little charms on ribbons running underneath the cake, or stick a plastic flower ring into the top of 10 cupcakes, frost over enough cupcakes for each guest, the guests who find the rings get the flowers.
