Pokemon Tower Defense Glitches
Sunny Day Glitch
There is a Glitch on route 1 if Sunny Day is in effect the game will freeze.
Skip The Elite 4 Glitch
If you get to the Elite 4 and think they're too hard, use this glitch. If you can't get past the first of the Elite 4, go to the Trading Center and go to the black screen while fighting the Elite 4 glitch fix page and click on it. Even though you didn't beat them you automatically beat the Elite 4 and you can move on to the Champion! This glitch has not been fixed.
In an earlier version of the game, right after the x2 speed button was added, there was a glitch where Pokémon would evolve two spots higher up the Pokédex instead of one when x2 speed was turned on. For example; a Dratini would evolve into a Dragonite instead of a Dragonair at level 30 and a Magnemite would evolve into a Farfetch'd. Because this is a glitch that has been fixed, higher evolutions that are a lower level are rare and have high trading value.
Evolution Glitch (Hacked Arcade Games only)
On January 30, 2012, There was a glitch where you could get shadow pokemon without spending any Casino Coins. The Shadow Pokemon would not be able to be accepted, thus being useless. This is currently fixed.
Adoption GlitchIn the Adoption Center in the Legendary Shiny Adoption-only Pokémon list if you go to the top bar (that shows the web page address). Change the last 4 and change it to a 5, The Pokémon will turn into X's and be 1 SnD coin. This also works with the other adoptions and the Avatar Store. However, this will just cause your SnD coins to be eaten up with no reward.
The Alive Glitch is the result of repeatedly clicking a Pokémon when it is about to faint. When it faints, it will be unmovable. However, it can still attack.
Ability GlitchThe ability glitch occurs with Blaze, Overgrow and Torrent. To perform the glitch, just leave the Pokemon with the ability out. Use a Potion or let Celebi (in Celadon Gym) heal it. The Pokémon will still have its glow. This is not a glitch as it says it activates at less than 1/3. It doesn't say it will deactivate at more than 1/3.
When the speed button was added with the levels that bosses could attack, the was a glitch that makes the boss Pokémons invisible.
To perform the glitch, go to level Cinnabar Island, put all your party at the top waves until wave 30 where no more Pokémon are catchable. Place all of your Pokémon at the bottom and defeat all of the Kabutops, Omastar, and Aerodactyl. When they are all defeated, you can see the Invisible Bosses.
This is actually common. Once, let's say Toxic was not introduced in v6.0 and was added in v6.1 as a TM, once that Pokemon you taught Toxic is used in v6.0, the enemies will freeze including your Pokemon but if your Pokemon already has a target, it will continue until the target's done.
In addition, if your pokemon has no moves (from hacking), everything will freeze.
Final Gambit Glitch
Win with No Candy
Sometimes if all the candy was taken, the level would continue until you win. This glitch was fixed.
Perish Song Survivor Glitch
If you have Jynx or Lapras that knows Perish Song, if you pull them out right after they do Perish Song, they will survive and you can use them again.
On the Pokemon Center, in the Daily Gift , if you've finished even the latest level or complete the requirements, there is a chance that it will say "You are not eligible for this code" and when you go back, it will say "You already bought a Gift today. Come back tomorrow for another Gift."
Game Corner Glitch
On the Game Corner , if you have at least 300,000 Casino Coins , if you purchase a "Non-Evolved Shadow Pokemon," there are chances it will consume your 300,000 coins and it will say that you don't have enough coins.
Unable To Dispatch Glitch
Sometimes you'll be unable to place a Pokémon on the field. When you click it, nothing happens, or it blinks for a second and then goes back to being unselectable. It's usually the second Pokémon on your team.
Invulnerability Glitch/Health Multiplier Bug
In the two final stages before you reach the Unknown Dungeon, there would be times that the last two of the Elite Four and Ash would not be able to do damage to you at all. This also affects the first two of the Elite Four, however; you can still be frozen on the first, poisoned and confused on the second. Other enemy attacks do not do any damage at all.
Edit: This is said to be the Health Multiplier Bug. Every time the health resets between battles, your health is multiplied by a certain amount, which makes it look like you're not taking damage at all.
Black Screen Glitch
In the final three levels, when you finish the level, a black screen might appear and freeze the game. Luckily, Sam has added a link to fix this glitch in the Pokémon Center .
Wave Stop Glitch
In the Unknown Dungeon , the waves may stop appearing at a random time. This only occurs in blue version for some reason. This has been fixed.
Pokémon Trading Center GlitchWhen searching for trades, you may have the problem when scrolling down. You may find that the Pokémon Center will fade and morph the trades together. If you go to another window or tab and back, the background will go black. This happens to FireFox more commonly than any other browsers.
Move Swap Glitch
Problems with the games programming caused Pokemon's movesets to swap when a player saved his game, resulting in pokemon with moves that they shouldn't know.
Caterpie/Weedle Devolution Glitch
In V1.22, whenever a Caterpie or Weedle evolved in a level, after it ended they would devolve back into their starting form while keeping any moves they had learned. This glitch was patched by Sam quickly, so not many of these exist.
Time Stop Glitch
If you have a pokemon without any moves and put it in field, it will "stop time" such that the opponents Pokemon stop moving. If you time it correctly, your pokemon will keep attacking, but the opponent's pokemon will be unable to attack. This doesn't work in PTD2, as once you transfer the pokemon, they will relearn the moves.
Skip Power Plant, Seafoam Island, Victory Road, and The Elite Four
Go to the Pokemon Center and go to the Elite Four black screen fix, then click it and it will say that it has been fixed and the Champion level has been unlocked. (Note: you do not need The Elite Four level unlocked. That is the glitch. You skip the Legends areas and the Elite Four. Then you have beaten the game and then you have all the time to go back and find the shinies-or shadows- to get the legends' other forms.) Hope I helped! BTW. This is DarkraiShouldBeInThisGame, and, it shloud be in this game.
Pokemon Tower Defense Generations
Doing Nothing Glitch
If you're doing nothing on Cherrygrove City , it'll come up as if you beat Cherrygrove City.
Incomplete Bidoof Glitch
As the 2013 annual April Fools prank, Sam decided to change every pokemon sprite into Bidoof sprites. However, Eevees were not affected. The Eevee sprite may have just been overlooked when Sam was editing the sprites.
The Grunt that guards the entrance to the ruins of alph has a Crobat . If you let the Crobat knock out the sixth pokemon in your party he will not attack any more pokemon anymore. This is useful for training low level Pokemon. This is also known as the Wing Method, and has been patched.
Shadow Mewthree Glitch
Infinite Coins in Voltorb Flip
When you manage to flip a x2 or x3, keep clicking on the card to continuously gain coins. Quit afterwards. This has been fixed.
