"This is a perfect game for the frailer sort," said Human Jem. "Little strenuous activity, but it still tests observation, response time, and searching skills."
This was a Deathworld game, so Glex knew the right question to ask. "What are you hunting?"

The grid, on further examination, held numbers within each square. "The goal is to get five of them in a straight line. Vertically, horizontally, or diagonally."
