What it is
Glowing fish drift across a quiet pond as the sun sets. Each one carries a letter, a number, a word or a picture. Read or listen to the question, then tap a fish to cast Olly's line and reel it in. Wrong fish simply wriggle free and swim on, and there is never a timer: fish slow down while you aim, and calm mode keeps them still.
