While there are different strategies for different maps, the one strategy that I’ve found to work regardless is you must manage your gold early in the game and raise your interest rates so that you’ll have enough gold in the later levels to buy upgraded towers.

• – My Tap Defense strategy is pretty simple. Use Arrow Towers with no upgrades as much as possible early in the game. Do not spend gold on more expensive towers like canons and water in the early levels.
• – One Cannon Tower costs about the same as two Arrow Towers. For about the first half of the game, having more arrow towers is just as effective and in many cases more effective than having only a few Cannon or more expensive towers.
• – Do not build more towers than you realistically think you’ll need to beat the level. It’s very easy to want to throw in an extra tower for good measure, but every gold piece you can save in the early Tap Defense levels
• – Upgrade your interest rate! It may be more fun to research new towers, but they won’t help you beat the game if you can’t afford to upgrade them later. I use all of my Halos except the last two on level 43 to upgrade interest.
• – Don’t spend a lot of gold building fancy towers just trying to beat the bosses. You won’t lose much by letting a Devil or Hellbat get through, but you will completely mess up your chances of beating the game if you spend ¾ of your money trying to build expensive towers to stop them. The bosses are usually two to three times more powerful than the creatures in the levels before and immediately after them. Save your gold!
• – Place your towers strategically. Anywhere there is a corner on the path or a U shaped turn, should be the first place you put your towers. Those should also be the places that get upgraded towers later in the game as they can shoot at the enemy for the longest amount of time.

Below are screenshots and brief descriptions of each level as I went through a game to show you how to beat it. It’s not a perfect game on my part, but I just wanted a quick and dirty demonstration to show you general tower placement and strategy for beating the game.

 

Level 1 – Tap Defense for iPhone

For level one, you can usually beat the Gremlins with only two Arrow Towers.

 

Level 2 – Tap Defense for iPhone

Add a third tower to beat the locusts. Occasionally a fourth tower may be needed

 

Level 3 – Tap Defense for iPhone

The Succubi are slow but quite tough. You will need at least 5 Arrow Towers to beat them.

Level 4 – Tap Defense for iPhone

The Cerberus are fast and tough. I used 7 Arrow Towers to beat level four.
 

Level 5 – Tap Defense for iPhone

To beat the Demons on level five, I add two more Arrow Towers for a total of nine.
 

Level 6 – Tap Defense for iPhone

I went with 11 Arrow towers on level six.
 

Level 7 – Tap Defense for iPhone

I stuck with 11 Arrow Towers to beat the Hellbat on level seven.

 Level 8 – Tap Defense for iPhone

You will probably need 11 or 12 Arrow Towers to beat the Gremlins on Level 8
 

Level 9 – Tap Defense for iPhone

Fourteen Arrow Towers beat the Locusts on level nine.

 Level 10 – Tap Defense for iPhone

The Succubi are a bit faster on level ten. 16 Arrow Towers did the job.

 

Level 11 – Tap Defense for iPhone

The Cerberus are fast and tough. 19 Arrow Towers were used on level eleven.

 

Level 12 – Tap Defense for iPhone

I stuck with the 19 Arrow Towers to beat the Demons on level twelve.

 Level 13 – Tap Defense for iPhone

I added three towers on level 13 to take out the Firecats. They are very fast.

 

Level 14 – Tap Defense for iPhone

I didn’t bother adding any towers to beat the devil as I’d have to spend a lot more gold on enough towers to beat him than I’d get. Better to save the gold and get more interest after the level.

Level 15 – Tap Defense for iPhone

I added two more Arrow Towers for a total of 24 to take out the Gremlins on level 15.
 

Level 16 – Tap Defense for iPhone

You shouldn’t need to add more towers to beat the Locusts on level 16.

 

Level 17 – Tap Defense for iPhone

Add in another two Arrow Towers near the start of the path to take out the Succubi on level 17.

 

Level 18 – Tap Defense for iPhone

Add one extra tower to take out the Cerberus on level 18.
 

Level 19 – Tap Defense for iPhone

Several more towers will make short work of the Demons on level 19

Level 20 – Tap Defense for iPhone

This is the breaking point. On level 20, I add four to five cannon towers and three water towers. The Firecats are just too fast at this point to only use arrow towers.
 

Level 21 – Tap Defense for iPhone

If you want a shot at beating the Devil, you’ll have to upgrade some of the cannon and water towers on level 21.
 

Level 22 – Tap Defense for iPhone

You can get by level 22 without upgrading or adding towers if you already did it in the previous level to beat the Devil.

 

Level 23 – Tap Defense for iPhone

You’ll have to upgrade more of your cannon towers to beat Cerberus on level 23.

 

Level 24 – Tap Defense for iPhone

Continue upgrading your cannon towers to power level 2 for the Firecats and Succubi on level 24.

 

Level 25 – Tap Defense for iPhone

Upgrade your existing towers as needed on level 25 to defeat the Cerberus and Demons.
 

Level 26 – Tap Defense for iPhone

You can probably cruise through level 26 without upgrading or adding anything.

 

Level 27 – Tap Defense for iPhone

You can get by level 27 without upgrading anything as well.

 

Level 28 – Tap Defense for iPhone

If you want to beat the Devil and Hellbat, you’ll need to upgrade someof your cannons to power level 3.

 

Level 29 – Tap Defense for iPhone

Time to upgrade some of your water towers to power level 3

Level 30 – Tap Defense for iPhone

Upgrade a couple of more cannon towers to power level 3 to beat the Locusts on level 30.

 

Level 31 – Tap Defense for iPhone

Upgrade the rest of your cannon towers and water towers. Also, add two more water towers above the path near the cannons to beatch the Succubi. On level 31

 

Level 32 – Tap Defense for iPhone

You’ll need all of your cannon towers upgraded to stop the Cerberus on level 32
. 

Level 33 – Tap Defense for iPhone

Add two more cannon towers and upgrade them as well as the remaining water towers to power level 3 to beat the Demons on level 33.
 

Level 34 – Tap Defense for iPhone

Sell four arrow towers around  your cannon and water towers and replace them with upgraded cannon and water towers to beat level 34.
 

Level 35 – Tap Defense for iPhone

Stick with what you’ve got and you can stop the Devils on level 35.
 

Level 36 – Tap Defense for iPhone

Upgrade two of your cannon towers to level 4 power level and you will have no problem with the Devil and Gremlins on level 36.
 

Level 37 – Tap Defense for iPhone

No need to upgrade, you can take out the Locusts on level 37 with what you’ve got.

 

Level 38 – Tap Defense for iPhone

Just another map.. Do nothing and cruise through level 38.
 

Level 39 – Tap Defense for iPhone

If you want to obliterate the baddies, sell all the arrow towers behind the water towers and replace them with cannon towers. Don’t upgrade them yet! Save that gold for after level interest on level 39.

 

Level 40 – Tap Defense for iPhone

Upgrade those new cannon towers and add a couple more to beat level 40.

 

Level 41 – Tap Defense for iPhone

You should have what you need to kill the Firecats and Devil in level 41.

 

Level 42 – Tap Defense for iPhone

You already have what you need to wipe out the Hellbats and Devil on level 42.
 

Level 43 – Tap Defense for iPhone

Last level! The evil Politicians (aren’t they all???) are trying to escape from hell. Use a halo to research Storm towers then use the two you get at the start of the level to upgrade your interest one last time. Set up two to three storm towers near the start of the path and you’ve got this level BEAT! Pause the game before the last Politician is killed and sell off half of your towers or more to collect interest on them at the end of the level.

VICTORY IS MINE!
