Boosts are skills that can be improved by spending Coins and Gems you've picked up within the Maze.
Each Boost has 7 levels and with each level you will increase your chances of survival and success.
Before each run you will be able to spend coins and/or gems to upgrade your Boosts.
Simply tap on the button for the Boost you want to upgrade. The cost for a single upgrade is shown on the button.
You can upgrade each boost to the maximum level as long as you can afford the cost of the upgrade.
As you improve your Boosts, they will become more expensive.
You can pick up Boost drops within the Maze that will activate the Coin Magnet and Time Boosts.
The Sprint and Stamina boosts allow you to sprint faster and for longer.
Upgrading your skills is key to surviving the Maze.
