The Game of Asha

Answers

The game is, or course, chess. The reason the promise was never fulfilled is that it would have required over 18 quintillion (18,000,000,000,000,000,000) grains of wheat. Try multiplying it out for yourself. That much wheat would weigh, conservatively, 500 billion tons, far more than our planet has yielded in its entire existence.
