Gem Tower Defense Strategy
Play Here: Gem TD
With the ability to build anywhere on the map except on one of the six waypoints there are virtually an unlimited number of strategy options.
In this screenshot I tried a simple maze that covers the 2nd and 4th waypoints. In this system the creeps travel through your entire maze 4 times. You could make the maze much larger but with this system I never run into trouble against the ground units so I don’t bother.
Key Towers:
Dark Emerald Tower:
This tower is absolutely vital to any strategy. Other towers with slow effects (ice/poison) become ineffective at higher levels as creeps get a higher and higher min speed. This tower fully upgraded stops monsters for 2 seconds in about 1/6 shots. I suggest building 4-5 Dark Emeralds.
Silver Knight Tower:
I strongly suggest building a centralized silver tower as your first. These aren’t very deadly late in the game but they are key in getting you to that stage.
Blood Stone Tower:
These are very deadly mid level towers if you do not upgrade them. After you get 4-5 Dark Emeralds set up I would upgrade these the Blood Stones with the Emeralds. This makes for an effective late round combo.
Hidden Towers:
Great Opal:
I’m pretty sure you can build ‘great’ gems for each color but the Opal has been the only one I’ve managed so far and probably the most valuable. The has a huge aura that gives all towers in it’s range +50% attack speed!
Note:
I would like to see a new tower defense game that gives you the option to turn off missiles. It seems that this causes quite a bit of lag in almost every TD.

Will this be on Xbox Live or PSN?

It is a web based tower defense game developed in Flash. I don’t think there are any plans on expanding this to a console but you will have to ask the developers.

Egyptian Gold is vital too, in survival, EVERY EVERY EVERY round is weak to it after 40(?), it does criticals, -8 armor to targets, good damage, good range, and the ingredients are easy enough to get (P. Am., Flawless Am., Flawed Dia.).

Egyptian gold is vital. It seems that your armor modifier towers are able to stack. That is a big deal when you have a high tower density. You still need damage boosters and ice/stopper towers but don’t overlook armor modifiers.

I can’t seem to stop the flyers after lvl 40..
any tips?
January 26th, 2008 at 7:42 pm
@Dierckx - buy lives…that seems to be the best way to get past those damn flyers.

I just made a malachite tower not entirely sure on the combo. btw what does the cooldown period mean?
January 30th, 2008 at 12:58 pm
The malachite tower is really weak at around level 25.
February 1st, 2008 at 7:04 am
how do u get “great” towers?
February 3rd, 2008 at 8:38 pm
Cooldown is the space of time between shots. And a great tower is what you get when you combine two perfect gems of the same type when you’re placing gems.
February 5th, 2008 at 1:30 pm
how do you get a graet tower
February 5th, 2008 at 11:19 pm
Seriously, Gmaners? Did you seriously just ask that RIGHT AFTER it was answered? C’mon! RTFA!
February 8th, 2008 at 10:09 pm
will there be a second map at all
February 12th, 2008 at 4:07 am
Just some information for people who might not know, gem TD is not exactly a new game. It was originally a user created map for warcraft 3 and then copied here cos it was so popular. Not sure if the original creator made a flash version or if someone else copied it, but highly doubt it will appear in a console as a game.
February 12th, 2008 at 9:11 pm
there is also a tower that i found called star ruby but i forgot the combination!
February 12th, 2008 at 9:12 pm
if you know the combination plz tell me!!!
February 12th, 2008 at 9:44 pm
isnt star ruby part of blood stone???
February 18th, 2008 at 6:28 pm
eek its something like chipped ruby flawed ruby and the chipped purple idk i havent played that long yet
February 19th, 2008 at 1:48 pm
i got the great emerald and its 250-250 dmg with deals 50 dmg poison every second and slows movement by 50% for 30 seconds
February 23rd, 2008 at 10:13 pm
their is a suposed “uber crystal” too but you need 4 perfect gems of the same type in one placing(which is a one in a very very VERY lot) you can see it in you tube but i will find out the hard facts when i can because i have no idea how to do probibility.
February 23rd, 2008 at 10:17 pm
and you can find out all the ’special’ towers recipies at www.gemtowerdefense.com (the original site)
February 27th, 2008 at 7:54 pm
the greatest combo i can think of is the unranium tower and a perfect emerald/blue, they combine to reduce the speed of the creep to 0.05, it basically keeps them stopped
March 19th, 2008 at 1:21 pm
Um…. this is not a web game, nor is it developed in flash… its a custom map for the warcraft III frozen throne expansion game.
March 20th, 2008 at 12:36 am
Gem TD is a web based game as well as a WC3 game.
April 20th, 2008 at 2:00 pm
I dont know the combo but a mystic black opal was the key to my success, it gives 40% damage to surrounding towers!
May 1st, 2008 at 6:30 pm

May 10th, 2008 at 4:43 am

May 19th, 2008 at 3:12 pm
I got a great amethist, which managed to stop any flyers even getting to the second checkpoint. Really is a good tower.

May 29th, 2008 at 7:54 pm
Yes, You can make great towers of all the main gems, you do so by combineing two perfect gems.
June 5th, 2008 at 10:54 am
how do you get the chance to “buy lives?”
June 7th, 2008 at 12:47 am
try using red crystal along with your other armor reductions and you should find air quite easyer
June 7th, 2008 at 2:23 pm
i got a great amethyst u have to put 2 perfect ones together
June 13th, 2008 at 3:12 am
I just calculated the probability of being able to create an uber stone when placing, assuming 10% of your gems are perfects. Assuming I didn’t screw up it’s 0.046%. Good luck!
June 17th, 2008 at 7:55 pm
All the combinations are on their website. http://www.gemtowerdefense.com/ scroll down to view
June 19th, 2008 at 12:25 am

June 24th, 2008 at 11:26 am
Lol really nice.. I’ve tried great opal and great sapphire
August 5th, 2008 at 2:21 am
i have had 5 great,s in one game XD OHH IN MY SANDBOX!
September 25th, 2008 at 4:30 pm
lol when i play extreme i actually do not need any tower but the anti red crystal, build a malachite and then build a spirla around it, at lv 20 you can grade it to lv 3 and when you are not totally unlucky you will win the game easily…no way to lose^^
one bloodstone with a high level will beat everything too…spiral is the way to win 
im a gem td nerd and got min 10 top 50 entrys…at surv. gold is the best way
