How can I shorten / speed up time in Zombie Farm?

There are two ways to do this. One way is when a user does a Zombie Farm staking challenge, the staking time can be shortened by staking more than the minimum required for the challenge. The more you stake, the shorter the time it takes to complete the challenge. The other method is to pay the CWS directly after the challenge has entered the countdown to skip the countdown and complete the challenge instantly.
