This app does not behave anything like the childhood game of Snakes and Ladders and I found it to be thoroughly disappointing. The die may roll, but you dont feel like you have any input other than rolling the die. Perhaps I am missing something, but you roll the die, and your icon does not move on the board. The icon belonging to the opponent does move, but not until after several throws of the die.
I recommend that you pass on this game - at least until it has good instructions and works properly.
