Hourglass
It is the first icon on the lower right hand side. You fill the hourglass by making matches on the board with the tiles that have the hourglass icon on them. The hourglass adds additional time to the rope timer at the bottom of the screen. At first you get an additional 15 seconds with your first upgrade. You have to upgrade 2 more times in order to get 30 and 45 seconds extra. Always use the hourglass power up as soon as it is available. Don’t save it as it does not gain power if it just sits there.
Army
The army power up is the middle icon that is in the bottom right corner. When you use it they will destroy a certain percentage of your board at a time. When you start they destroy 15 % of the board, additional upgrades will give you 30% and then 45% destruction of the board. Always use the army power up as soon as it is available. Don’t save it as it does not gain power if it just sits there.
Hammer
The hammer is the last icon on the bottom right hand corner. It can destroy one tile at a time in the beginning. Later it can smash several tiles when it has been upgraded.
