I can't seem to activate the far right squares in order to reach the last rock barrier and chests. Making matches next to those last empty squares doesn't "fill" them, so I can't reach the top! I have a screenshot of the issue...not sure what to do to progress?...

This game need a tutorial not only that stupid match three symbols and more of what gameplay you have to deal with ! Also: why,why comes that hint for next move ! I can`t find a way to disable it !!!
