What is the eaziest way to beat balloon tower defence 3

choose the first map the one with grass and dirt road now put two or three reg. monkeys in the beginning if any get past use spikes when you have enough money buy the boomerang and set it kinda close to the beginning and definitely upgrade to it being able to destroy lead balloons after you buy more defenses you will run across a spike o pult just set that on the straight away (the straight line) and it will become very handy at times now get the super monkey after alot of work and set it in the middle and upgrade it fully it should take up the whole map =) and keep using spikes when needed and after a while you won
