To correlate a main message with an additive message since the two messages are arbitrary ones received from the other side of communication and thereby to improve enjoyableness.
The subject communication terminal is so designed that the main message is outputted from an LCD (liquid crystal display) 40 when a main message reading operation is conducted after an e-mail message comprising the main message and the additive message is received from the other side of communication. When an additive mail reading operation is conducted subsequently in this communication terminal, a puzzle game screen is outputted from the LCD 40. The outputted puzzle game screen progresses according to rearranging/rotating operations and the additive message is outputted when the state of progress of the puzzle game screen satisfies prescribed conditions.
