How do I use the power ups in Element Blocks?

[AARPTeri]

In Element Blocks, you have access to two power ups, and both are perfect for getting you out of a tight spot when your grid starts become overcrowded. They are:

• Dynamite – Removes any blocks in a 3x3 area of your choice
• Lightning – Clears all blocks of one chosen color

However, these power ups don’t come easy. You’ll need to buy them from the bottom-right corner of your screen – but in order to do that, you’ll need to collect stars. The main way to get stars is simply to keep playing the game. Every once in a while, a block on your grid will be covered with a star. If you clear the row that the block is in, you’ll get the star!

Dynamite costs 15 stars to purchase, and lighting costs 25 stars, but they become more expensive with each use. You can only hold one of each power up at once.
