Opinion of Blog Owner :
Well, this is my great game in 2009, I still remember when I played this game was at fasting month. I spent my time while I was fasting. For the first, I was rather doubt with this game. But then I'm sure this is the best strategy game that I've ever played. The graphics are all simple, but its playgame, I'd like to give the score 9.5. So, read hints below in order to play more fun.
Useful Tactics:
World 1
This area is very easy, and is mainly just a tutorial to the game, Use whatever plants you have, this early in the game. But make sure you have peashooters and sunflowers.
World 2
Now this is when it gets a bit harder, the sun no longer falls from the sky, what I did was i used puff shrooms (the free mushrooms you get) and sun shrooms, then when I got that set up I would start setting up peashooters and repeaters. And at the end of the level, zombies spawn from the graves, so try to take them out early in the level (P.S. The graves give some good stuff, crystals, plants, and sun)
World 3
Ok you made it this far, now we are dealing with a completely different kind of strategy, what I did was I got lilipads, cattails (cattails are VERY strong, they can attack any lane, and they shoot two spikes at a time) I also had wall-nuts, cherry bombs (for emergencies) peashooters and repeaters. You want to make each lane equally strong. And make sure you buy the pool cleaners, they help a lot.
World 4
Ahh world 4, the hardest world in my opinion, basically its world 3 but you cant see half the screen, luckily you get a plantern in a level or two and you can see it then. I was stuck here for a while, but when I used cattails it was so much easier, just use the strategy from 3 and 4, i recommend at this point using sun flowers, and garden rakes (can be bought in Crazy Dave's shop for 200$" You REALLY want to use the torchwood, seeing as how they make your peas to DOUBLE damage. I personally have never really used the snow peas, but if your comfortable with them go ahead.
World 5
And last but not least, the roof level, make sure you buy the roof cleaners, you will need them. Here is what I did the whole time, first two columns are sun flowers, third column is cabbagepults, fourth column is corn pults, and fifth column is tall-nuts. When you get the melonpults I suggest replacing column two with them. As for cob pults, dont use them, they take too long, and they're not that good. Bungee zombies are best countered by umbrella leaves. Get one or two in each row, NO MORE, they protect the eight squares surrounding them, and their own. And my last tip for World 5, is gargantuans, here's the thing, if they didn't throw the imp off of their back, then cherry bombs would be all you need, however, I would advise using a cherry bomb, then using a jalapeno on the row, to kill the imp and the gargantuan.
Dr. Zomboss
This boss is very hard the first few times you fight him, so try doing this. Save all the ice shrooms and jalapenos you get, you need them to destroy his fire/ice balls. use all the other plants strategically to fight off the normal zombies. You WILL have to use ice shrooms and jalapenos occasionally, jsut save as many as you can.
How to earn a lot of money
Here is the best way without a doubt. You want to beat adventure and get your zen garden. Then play endless survival and adventure mode again to get plants. Water plants and mushrooms give you 10,000$ just to sell them and they give you 2 diamonds when they're grown to full, which pays for the food, and more. Normal plants like daytime plants and marigolds only give you 8,000$ to sell, but they give you two diamonds when grown to full. (Marigolds only give one diamond).
Hints
To increase your plant growth
First of all you need to disable the full screen then go to your zen garden after feeding the plants normally it take 30min or feed them again. To feed them all you have to do is to change your system time for earlier this will increase the growth & also buy more plants from Crazy guy.
Favorite Plants:
Even if you have "favorite" plants that you like to use, mix it up and use a plant that might be out of your "comfort zone". The game is fairly forgiving of less than perfect play, and you might find that blowing up zombies in a conflagration of potato wedges or smashing them with a squash is more fun that you thought it would be!
Increase plant growth:
Disable full screen mode. Go to your zen garden. After feeding the plants, it will normally take thirty minutes to feed them again. To feed them all, change the system time to an earlier value. This will increase their growth.
Final Boss Trick:
When facing the final boss in the game, he will launch massive fire balls and ice balls at your plants. The crush everything in their path except zombies(basically, all plants in that row), but there is a way to stop them! To destroy the ice ball, you must use a Chili Pepper in that row. To destroy the fire ball, you must use an Ice Shroom, but with a Coffee Bean, too, or else it'll fall asleep.
Easy money:
Get the Zen Garden. Water the plants until they do not need anything else. Advance the system date ahead. The plants will need water again. Buy new plants, grow them to full size, then sell them. Repeat this to earn more money. You can also use this technique when you have to get Marigolds in Crazy Dave's shop when they are out of stock.
