First is first, you start with monkey. Not any monkey, a good monkey Da?
Yes good monkey can take you to round 25 or so without help from tovarishch. Is Comrade.
You might say "What monkey is good monkey?"
Monkey Dart 2/3
Monkey Engineer 2/3
Monkey Pirate 2/2
Monkey Ninja 3/1
Are good monkey to use

If you know any other monkey that work, us it.

So it work like so, you start with this monkey and you only use this monkey until he need help from tovarishch then you buy a good tovarishch. However during the time our friend is alone, he make money for monkey, you need farms bananas, this well get you money like American Capitalist.

So lets say you get to round 20-29 and you just bought a tovarishch, you have three or two farms 2/0, do not buy long banana life it is stupid, buy strong socialist banana farm or do it yourself. Mama always said if you want something done right, do it yourself. This is part of game when you buy village for chelovek, you need to tell your monkeys where kemo bloons are hiding, they try to sneak up on motherland.

A village is important for communist monkeys, they have cheaper upgrades too, this is important for capitalism.

Round 30s, you should have good monkey and two or three monkeys to use.
By now you should know your weakness, it's either strong bloons or floods of bloons and depending on what you weak against is what you do.

Strong Bloon Defence Tac
-Monkey engineers with monkey fort (Village 0/1) is very effective
-Monkey Cannons with the monkey are also very good
-Monkey Sniper goes without saying, set to strong, no weak men in Red Army
-Monkey Spike Factories, place then 1/3rd into the map and go 2/3 or 2/4, they eat through big blimp bloons like blin, this mean pancake.

Flood Bloon Defence Tac
-Here in mother Russia is cold, I'm sure weak bloon would not survive a summer here so buy ice tower a 3/2 ice tower wont let any gopnik bloons through unless they wear coats.
-Monkey Glue Gunners are also good for slowing down hoard of gopnik, I personally use the left path but if you think right path is better, then go right pizda.

When we get to harder and longer rounds, is what your mother said, you need more MOBA defence and a super monkey. Now personally I do not believe in war hero or individuals having that much credit but super monkey will rule with fist of iron. Go left path go right path, equally those bloon blins will not cross towards motherland this time.

Now before I finish I will tell you one finally trick for last Round, round 85. As you probably know it is the baba yaga, and she is pissed (mad not drunk silly englishmen). 5 ZOMGS. This means weak tiny army of tovarishch will not survive. Fortunately you do not have weak tiny army of tovarishch. However you must nuke the enemy. Nuclear deterrence theory only works in theory, like communism. These ZOMGs dont have balls to retaliate. "How do I get nukes" You ask in weak american girly voice? You sell capitalism farm which you should have been upgrading throughout game and buy Monkey Pilot Ace 0/4 and you drop the fat man on bloon gopnik. You sell Monkey Pilot Ace 0/4 and buy another! Drop the fat man again and again and keep selling and buying Nukes until you make battlefield Chernobyl.

Good, like my friend and as always, have nice day.
