Rubies

Rubies are the game's premium currency. They appear as small, shiny red gems.

Getting Rubies
Tap "+" in the top right of the screen to purchase more Rubies. They are primarily purchased with real currency via micro-transactions and are charged to your iTunes or Google Play account. They can also be earned by leveling up through Experience or completing Bingo and Event Missions.

Using Rubies
Rubies can be traded for Hearts or Coins or used for Magical Time, which adds a few more seconds to the game (if prompted).

You can also use them to make missions easier
