Director ! Give the ordering books your seal of approval.
You are a director. Your work is to push your seal of approval.
Ordering books appear in sequence. If the contents of them are same as a sample, you have to stamp them with the seal of approval. If the contents of them are different from a sample, you mustn't stamp them.
When you don't push the seal though it is contents same as a sample or push the seal though it is contents unlike a sample, you are got angry at by the president. If you are got angry at 3 times, the game is over. You compete for score before becoming the game over. You can compete with other people for score by the ranking.
Your reflexes are tested by this game. Let's stamp the mass ordering book with your seal of approval.
