Chose a character for Test Your Might and Test Your Sight
Hold the D-Pad in any direction, including the diagonals. For example, hold [Left] to get Scorpion every time.
Free Sight
Once you buy the second most expensive coffin, which is 10,000 Koins, you should get Free Sight. To know where it will land, you must do the following. First, record the result for the first Test Your Sight. It should be Kenshi. The correct bottle will be the first one to the left. The second should be Kitana, and so on. You can keep recording the results and if you miss one, make be sure to see which bottle was the correct one. The next time you play the game, you will know which one to choose. For example, Kenshi will be the first one that comes up, and you will know which bottle to choose.
