What Boosters Are Available?

There are a few boosters available in this game, that are unlockable as you play the various levels.

They allow you to do a number of things. 

• Extra Turns  - By unlocking this (which requires six gold bricks), you're able to continue your current run for five additional turns, on top of the ones you're already provided with. 
• Tractor - A single-use power-up that clears away a whole row of vegetables, in case you're stuck or just want to clear away some of the debris that can't be matched up right away. 
• Shovel - This enables you to dig up and remove one piece from the board. If it's a piece that's required in your collection, it'll be added to your total automatically. You can use this up to three times before needing to recharge it.
