What's the best strategy for Survival: Endless mode?

Solution 1:

This website lists a bunch of strategies. Here is one example of a strategy:

Essentially, at higher levels, almost all strategies rely on having a constant supply of Cob Cannons to take out the Gargantuars with. The Winter Melons are used to slow down incoming enemies. The Gloom Shrooms in the pool are to damage pool-dwelling zombies and also attack zombies in the second and fifth rows. The Gloom Shrooms near the house are to kill Miner Zombies in the event that they spawn, and the Banana Leaves are to protect against Catapult and Bungie Zombies. The Ice-Shroom is placed in the pond to wake up with a Coffee Bean in the event that it needs to be used, Spikerock is to protect against vehicles and zombies that get too close to the Cob Cannons, and the Twin Sunflower to generate sun.

Solution 2:

I didn't come up with it, but I made it through 114 flags with this:

Source (not my video):

"Zombonis" in the outside lanes seem to blow up just before running over the first plant, the plants in the pool take care of the inside two lanes. If there's a zamboni right behind the lead one and not on top of it, you may have to help destroy it before it squashes something however. Also watch out for jack-in-the-box zombies that sometimes survive long enough to detonate in the lanes adjacent to the pool.

I pretty much just saved the Cob-Cannons for the big guys, replacing pumpkins as needed due to dolphin riders, and football zombies that manage to make it up to the plants along the top and bottom of the screen.

The one other thing is to absolutely plaster the lawn with sunflowers at the beginning in order to maximize your sun while the zombies are still pretty weak.

Solution 3:

If you put a double sun in front of the outside lines the zomboni's will still explode provided you have an extra gloom schroom more on the inside lane next to pool - in this way you will have more sun for longer. Only thing is when I get to 79 or 80 flags, the gargantuans are just too many - have no answer for that at all. cheers
