• This initial NIM game board has 16 stones arranged in 4 rows.
• You and GOD have turns taking stones from a ROW.
• On your move, choose a row and take 1 or more stones from it.
• Tapping a colored stone removes it AND stones following.
• You can tap multiple stones as long as they are in the same row.
• Tapping a grey (empty) position replaces removed stones to there.
• After taking AT LEAST ONE stone, just tap "Over to GOD".
• You will WIN if you leave just ONE stone in ONE row.
• You LOSE if you are forced to take the LAST stone.
• At game start, YOU may move OR tap "Over to GOD".
• Game start, is the ONLY time you have this "no take" option.
• Hint: At START, tap "Over to GOD" if EVEN color group counts,
otherwise take stone(s) to force this state on GOD.
• Hint: usually take to get 0, 2 or 4 groups of each color.
• Hint: BUT if all rows EXCEPT ONE have 0 or 1 stones,
then take from big row to get 1 or 3 single stone rows.
