This game had been invented by my daughter Lisa. It is a variant of the well-known Nim game. We have several leading zeros, and then integers from 1 to 3. Let x be the first nonzero entry. Then you may

- either change the first x non zero numbers into zeros (move 1),
- or change all numbers up to the second entry with value x (this number included) into zeros (move 2).
