NOTE:
There may be more than one solution to the Rancor puzzle. Below is one way to solve it.

General comments:
To solve this puzzle, you must recognize that a pattern exists between a particular coin and the 2 coins immediately below it. Specifically, when the 2 coins on the bottom of the 3 coins that make up a triangle are both silver or both gold, the coin on top has to be silver. When the 2 coins on the bottom are different (i.e. 1 silver and 1 gold) then the coin on top has to be gold.

For example:
Coins “B” & “C” above at start of puzzle are different (”B” is silver & “C” is gold) therefor, coin “A” has to remain gold.

Also, coin “C” and coin “E” are both gold, therefor, coin “D” must be changed to silver. This pattern exists for all coins.

Steps to solving the Rancor puzzle:
1) Start with ROW 2.
2) Click on the coins to flip them between gold and silver.
3) Flip the coins so that they match the pattern shown for “END OF PUZZLE” for ROW 2.
4) After you correctly match the pattern for row 2, the row of wooden levers immediately
below it will all flip down.
5) Proceed to ROW 3.
6) Repeat the process of flipping coins to match the pattern for “END OF PUZZLE” for
ROW 3. Again, when the correct pattern is matched for ROW 3, the levers immediately
below it will all flip down.
7) Continue this process all the way to ROW 8 to complete the puzzle.
