I felt that level 25 hasn't been explained very well, so I will break down each sequence for you. Sequence 1 - Look at the string of letters in the thought bubble. From left to right, decide if each letter is facing forward, like the normal letters R, E, and D, or backwards. If the letter is facing forward, click the right lens on the sunglasses. If it is facing backward, click the left lens of the sunglasses. Sequence 2 - Now look at only each letter R in the sequence and do the same thing. Sequence 3 - Same as Sequence 2 but with each E in the sequence. Sequence 4 - Same as the last two, but with each D in the sequence. Sequence 5 - I'm not sure if this is the actual solution, but this time do the sequence from right to left. You only have to do less than half of the letters before you're finished
For those that don't understand this game, this is how it works:
Start by looking at the customer's head to see what gem they would like at the end of their chain. Then, search the board to see if you can find that gem next to a group of 3 or more other gems of the same kind. If you can't, just create a chain of 3 or more gems of the same kind. When you select your chain, it must be dragged off of the board in order to register as complete, meaning the last gem in your chain has to be at the edge of the board. Avoid the golden symbol with a star on it because it is a fake gem and you will lose a large amount of money for adding it to a chain.
My only complaint about this game is that there are too many customers in one round, so it takes awhile to complete.
