ABC Order is an alphabet game with a friendly wombat who blows letter bubbles. A row of letters hangs on a string, like C, D, E, with an empty space at the end. Which letter comes next? Tap the right bubble and it floats up into the row. A wrong bubble just wobbles, so there is nothing to lose. At the top, an A to Z strip shows the way, and every finished row sings along it. First children find what comes next, with a faint letter to match. Then they fill gaps in the middle of a row, and later they tap a jumbled run of letters in ABC order. Each stage visits a new place and wins a new set of bubbles.
