We bring chocolates, and some non-chocolate goodies, for those who have to avoid it, and then we play Bingo, winning a prize for a line, then for two lines and then for a full house, until all the chocolate is gone.
After a few rounds we do not clear the sheets once someone has a full house, but play on until everyone has won a prize. We have some larger eggs, and then a lot of mini eggs, so if our members have already won a large egg, then they can still win mini eggs, but leave larger prizes for others.
For those of us who are learning BSL it is a chance to practice our numbers.
