User blog comment:Sam Wang/BTD5 - Tips For Reaching High Rounds/@comment-5673359-20130807142456

I've never been up to w200 - but the best strategy I know is:

Get a monkey ace 2-4. When there will be enough MOAB's, use the nuke - you'll have about 30K$. Use that money on getting some TT's - like 5 - then get a monkey ace 4-2, 2-4, some TT's, and so on. I reached w113 then it freezed - but I had more than 18 TT's, exactly 5 2-4 and 4 4-2 monkey aces - plus some banana farms to get money, and monkey villages 2-3 to allow to shoot at all bloons.
