How do the in-game Power-up’s work?

There are two power-ups to choose from in the game Tier Booster or Large Claw. These power-ups can be purchased in-game or in the NC Mall. The Tier Booster power-up will allow you to up the tier level of your prize by one tier. So, if you grabbed a wood prize, you would be able to tier boost up to the next tier which is bronze. You still wouldnt know what your prize was, but you would receive a prize from a higher tier level. The second power-up is the Large Claw. Selecting the Large Claw power-up guarantees you grab 2 pods and receive 2 prizes.
