A preacher went into his church and he was praying to God.
While he was praying, he asked God, "How long is 10 million years to you?"
He replied, "1 second."
The next day the preacher asked God, “God, how much is 10 million dollars to you?"
And God replied, "A penny."
Then finally the next day the preacher asked God, “God, can I have one of your pennies?"
And God replied, "Just wait a sec."

1. The number can appear only once in each row.
2. The number can appear only once in each column.
3. The number can appear only once in each district.
