Big or Small is a gentle size game for young children. Quokka's bubble shows a little picture of what to find, so no reading is needed. It starts with two of the same animal, one big and one small: just tap the one she asks for. Then come tall and short towers, flowers and ice creams, long and short trains, caterpillars and crayons, and choosing from three. Later, line up nesting friends on the shelf from small to big, and stack rainbow cups with the biggest at the bottom. A wrong tap just gets a friendly wiggle, and help appears if you get stuck. There is no losing. Every stage visits a new place and wins a new family of nesting friends to collect.
