This walkthrough is for the classic mode on the classic map although a similar strategy would probably work on classic mode for any of the three maps.

This is not a no-leak solution, I ended up with 9 lives but was still able to beat the game.

So this is like a simple strategy and also the main complaint I have about the game. You can try a bunch of different types of tower placements but all those will fail. The easiest way to beat this game(this strategy is not no-leak) is to just use three towers: the basic tower, and anti-air tower, and the freeze tower. You don’t need any of the other towers. A row of fully upgraded basics deals enough damage to take out all 50 waves in classic mode.

Note the map layout below:

So you see where I’ve outlined the map in red? That where you’ll build all your towers, just straight down that row. First build three arrow towers spaced out. Then as money comes from creeps, build up to 8 arrow towers but leave room in the middle section for 2 freeze towers and 1 anti-air tower. After you’ve built 8 arrow towers, build a freeze tower, an air tower, then another freeze tower in the spaces that are left. After this part, it gets really easy, just upgrade all your towers uniformly when you get money. Upgrade the arrow towers first, then the Anti-air tower, and then the slow towers. Keep them all within 1 level of each other. This will give you enough damage to take down all 50 levels of creeps. I’m not kidding, its really that easy. At the end, you’ll have enough money to buy and fully upgrade sniper towers and flame towers with the left-over money but for beating the game you don’t need any of those special towers. At the end of the game all your arrow towers, you air tower and your freeze towers should be maxed out. The creeps that may get away include 1 boss creep(2nd or 3rd one) and the swarm multiplying creeps, its really hard to kill all of those, although you might be able to do it if you build 1 or 2 more arrow towers on the inside curve following the straight away. Thats all there is to this strategy. Have fun!

1. Check out the Sofa, click the top of the Sofa and take the blue tetris-like piece that is there

2. Look under the Sofa and take the Projector slide there. There is also a green straight piece under the leg of the sofa, get that too.

3. Go to the room right of the Sofa. There is a piece frozen in the glass so take the glass. Click on the blue man on the table, one of his arms is another piece, take that piece.

4. Check the drawers. Take the matches from one drawer and another blue piece from another. Now click the frozen piece in the glass. Click the matches and hold the match up to the frozen piece. Wait for it to melt, then grab the frozen piece.

5. Check under the drawer-desk and pick up the pin there.

6. There is a picture of squares to the left of the desk, click on the green square in the picture. You can obtain an “L” piece from the green square(you might have to click it a few times).

7. You need to solve the puzzle on the computer. The answers starting from the top row are: (3,5), mid row(2,7,9), Bottom(4). Then take the slide that comes out when you finish the puzzle

8. Go to the right, you’ll notice a box in the left corner, check it out and there is another blue piece behind a second box when you zoom in, take it.

9. In front of the door, there is a rug. Click on it and take the 3rd projector piece.

10. In the room to the right, there is a green ‘1′ on the clock, take it. Check the drawers and take the projector from the top drawer. Don’t check the other drawers for now.

11. Click the back of the drawer. Take the knife from behind the drawer.

12. There is a balloon on the floor in the lower right corner, use the pin to pop it and pick up the green piece there. Also grab the blue piece from the wall before zooming back out.

13. No you have a lot of pieces. If you remember, there was a green arrow and a blue arrow above the sofa. Go back to the arrows. Put the pieces you collected on the pictures according to their respective color(just drag all of them on, it isn’t a matching game).

14. When you finish, the green puzzle forms a 3 and the blue puzzle forms a 5 on the inside.

15. Go to the left. There are a bunch of squares above the take. Count 3 squares right and 5 squares up and take the knife to get the yellow piece.

16. Now go back to the place with the boxes and use the knife on one of the boxes to grab another projector.

17. Now you have 2 projectors. There are also two shelves, one is above to the left of the door while the other is above the table with the laptop, put them there. Put a slide in each projector(there is another project opposite on the other side of the door, put each of the 3 slides in a projector).

18. Now since you have the slides in place, go to the blue and green puzzle again and you will notice a code on the white sheet next to them. This is the code for the safe.

19. Go to the safe and enter the code in by clicking on the numbers in that order and take the yellow piece in there.

20. Now you have two yellow pieces and you will notice that the mechanism that controls the door is missing two yellow pieces. Put your two yellow pieces in the correct positions on the door and open it to get out!
