To beat the new challenge in Alexander's Vault, you will have to drop two Symbols through the exit on the board within the given time.
As this is a challenge, you will have to move both of the Symbols across the Conveyor Belt while making sure they don’t fall through any of the Teleport Tubes! If they do fall, this will result in you having to start the process again.
To move the Conveyor Belt, make matches with the Cog Gems. Each Cog Gem removed in a turn will move the Conveyor Belt one space to the right.
This means that you will sometimes have to make matches of more than one Cog Gem to move the Conveyor Belt the correct number of spaces!
