🌌Complete Guide to Merge Academy

You have gone as far as the game will allow at this time.  Chapter 4 has not been released, they limit the number of gems to 1,000.  My advice is to work on some of the items that take a long time to earn and keep them for future use.   I have 3 items that require a lot of moves to accomplish, so I work on them and just bank them until the next phase of the game is released.
