Two frogs hop from one lilly pad to the other, trying to catch as many flies as possible before the sun goes down. In the easy game (difficulty on B), the frogs jump in fixed arcs. In the hard game, you can adjust how high and how long they jump, which means you can miss the lilly pad altogether. Frogs and Flies is relatively mindless, but pretty enjoyable, and it tends to appeal to the ladies. – Atari Guide
