Mortal Kombat

This is not that hard. This requires you to complete all 15 Test Your  Slice challenges. The Bonus Tower only has 10 challenges (Challenges #7,  #21, 35, #49, #63, #78, #92, #106, #120 and #134). The last few challenges are tricky as a lot of bombs will be thrown into the mix. Use the sound cues to watch out for them and deal with them first before slicing the other items.

Ensure that you swipe the Hell Fire (destroys all objects on screen), Green Clocks (+5 second time bonus) and Toasty (gives you a lot of objects to swipe at for a short time) bonuses when they appear on the screen to easily clear the challenges.

Once you complete Challenge #134, you will unlock five extra challenges  which can be accessed directly from the Test Your Slice menu. Complete  those as well and the trophy will unlock after the last one.
