Here I list medals I cannot unlock for some reason.

I wondered if I should keep this list private but I figured it could benefit to look at for others.

If you have a medal in mind you can notify me but having it on this list is not guaranteed mostly because all of a sudden I may not have access to internet for some days/years.

Medal games that play in another tab that uses http

Newgrounds blocks every connection with other sites that uses http instead of https (s stands for secure and means the connection is encrypted). This means also Newgrounds own games that run in a separate tab. These medals would work if Newgrounds change this in the future. There are some cases where games also work on mobile devices and get the medals in that way.

Medals that don't award when reaching the requirement and that no one has earned for some time

A Fitting Title For A Game About An Astral Child, A creature In A Pot And A Weird Hole Somewhere Near Bali (True Progress and True Accomplishment. Tested several times in all ways I could. Once I got permanently flickering lines on my monitor while playing this that still stay. The game might be cursed.)

Boom Blast (YKnot and AD??? I do not know how to get them but not for watching an ad and I have tested pressing the buttons I could find.)

CAZE (All)

Crystals (All)

Deserted: Island Mystery (Escape!)

DOTMAN (All but the first.)

Drillionaire (Mixed material, Reduse, Reuse and Recycle.)

Edward The Rude (SuperUltraHyperRude. I suspect API time-out. Would probably work otherwise.)

Electric Rubber (Overnight Success. Really hard to decide to put it here or where the requirement is not met.)

Everyday Platformer (All)

Fridge Runner (The three medals for playing 10, 50 and 100 times.)

Fury of Frostbite (The medals do not always send. Most notably the points and the story medals. We need someone to properly test them because it seems like they are problematic for everyone. By the way I just got Frostbite's Envy While writing this and having the game unfocused. It could be a good idea to be patient.)

Ghostbusters B.I.P. #3 (Ready to believe you)

Hotlion LesracMiami (Game freezes when reaching a medal reqirement.)

Intense Room Escape (Escape!)

i saw her too, with laser (All)

It Came From Outer Space (The Player Knows Best, I'd Like To Thank The Academy... and possibly Showered in Gold because I am not sure you can reach $50000000 without an oscar.)

Kingslayer (Kingslayer)

Lollipoop (Clumsy Boy and Zealot)

Master the Guitar (Fretboard Expert)

PACO-PACO (Cake is a Lie. This may not be borked. Just hard to reach. I put it here because it is unknown how to get it. It is not for jumping over the portal five times in the same run.)

pixel invaders (100000 pts easy. Highscores over 100000 could still be submitted.)

[PREVIEW] Asteroid Bomber (First Hit!)

SNEKMEK (All)

snek REDUX (All)

Super Coin Clicker (All)

Super Pong Bros 65 (All)

Surf : : Aces (All A-grades in 20 surfaces.)

TDR RPG: The Quest for Xirang (Swinging at Nothingness)

tempO (50k Score and Marble Madness. Have not reached 100k Score and Marble Insanity.)

The Impossible Pixel Challenge (pixelchaser, pixelscientist and Deus ex.)

Tower of Towers (F*ckin' invincible. I used a cheat shown on the speedrun web page that skips the last dungeon. It could be so the medal works if you actually do it legitimately! Someone might need to test this who really likes this game.)

Trivial Trivia: The Newgrounds Collection (All NG Events and Jams medals. Scores cannot submit.)

Walk box 3 (Completed. Highscores submit and medal awards in-game.)

WAR IN BLED (EATEN BY BLED MONSTER)

Wouter's Robot (All but the first.)

ZS Dead Detective - Walls can bleed (All)

Medals which requirement cannot be reached and that no one has earned for some time (includes games that cannot load)

Crashzilla (Jackpot. The most crystals you can win in a spin is 250, but the medal requires 500.)

Crazy Alien Snake (25 tanks. I tested this alot a while ago but I cannot remember exactly. I am pretty sure you cannot destroy 25 tanks because when you have taken enough power-ups there won't be any tanks around anymore.)

Dandy Cave Explorer (Treasure Hunter and Maniac Run. A special case. It falls to the first category since it runs in a separate tab, but you can play the game on mobile. It is just that the game freezes when you are awarded the first medal and you cannot progress further than that.)

Hungry Little Bear (Cannot load)

Indie Jones (Voyeur. The video cannot load.)

Minigod (100 and 1000 humans medals. We lack a strategy for these medals. If someone earns them they should be taken away from this list. I only list them here because the author has no idea if they are possible to reach.)

Phase Shift: Lab Escape (The medals for completing three respective five loops in endless mode. This is just very hard so if you play well enough it might be possible. It takes some time so API disconnection could be another issue, but we get there if someone manages to do it.)

Pokikex (100. Getting this far should not be possible.)

SHOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO (Maxed Out. Something has happened with the game that makes it run slower. The last medal won't award. Probably by API disconnection.)

Shop Empire 3 (All but contractor and nice team. Something has happened that prevents you from getting any income. It seems like some users have found a way around this though.)

Sokoboom 2 (The game can only load in Ruffle, but it does not work properly in Ruffle.)

The WTF Game Experience (WTF Level)

Trap: Volume One (Seems like the game cannot load, but it just takes ages. You can start the game but nothing happens.)

Trivial Trivia: Impossible (100%. A bug in the game jumps two questions in a row and counts one as incorrect.)

Zombokill 2 (The game cannot load. For some reason you get True Fan, True Biker and Invincible Warrior when you try to start the game.)

Medals that others have earned recently but do not work for me

These are not really borked but probably require some specific OS/browser or are wrongly described so the requirement is something else.

AstroJump (Deep Space. Tecnically working but it is too hard for me.)

Big Smoke's Train Chase (Defeat the vagos medals.)

Bounce Back (Boomerang Master, Speedy and Super Speedy. The game crashes when I complete a level and I have to refresh. I can continue on the next level but not on speedrun mode and for some reason I lose my boomerangs. I probably just need another browser.)

Box Stack (All but the first and last, because I have not reached 500 points. It seems like many have problems with the medals for this game.)

Christmas ADVENTure 2018 (The game cannot load. I think it is for super fast gaming computers exclusively.)

Clicker (Take the 100. I even get the pop-up.)

Final Commando (Boss Master and Medal Medal. I have defeated the boss multiple times but it won't award me the medal even in-game.)

*Flight* (Very problematic game. I can play it just fine but like some other users the medals do not work. Sometimes they work in-game and sometimes not.)

FRIDAY NIGHT FUNKIN' (SPOOKY TIME and Just like the game. I tried more than once. I got the first medal on a computer I have no access to any longer.)

Half Dead (All medals are technically working I guess but the game has stopped to save for me. I can still load saves. The game is too long to play in one session.)

Intruder CT 2X (perfectionist. This medal works. I can just not get it because there is no way to reset your save.)

ITAZURA MADNESS (Medals stopped to send for me although they work in-game. I could try to reset progress but have not felt like starting over.)

JustAnotherSnakeClone (The screen shaker medals. It is hard to judge on them. If you get so long that you shove in power-ups into your mouth the game crashes. I have not been able to get the medals by staying short and maxing speed.)

Lollipoop (Adventurer. I think I have tested everything. There is probably a browser you need to use.)

Mechsican Standoff (Meet your Maker. Another problematic medal. *SPOILER****SPOILER* You are supposed to be able to fight the developers if you click on credits and then on the mellow minds logo. Earlier I was able to do this but now the battle won't start.)

Merry Christmas Tom Fulp (Gift Giver Pro. The game crashes in Opera but works in Edge and on Phone. On phone I got API disconnected too soon but on Edge the highscore did pass 10000.)

Perilous Journey (Bronze 10. I get the medal pop-up. Other medals and highscores are problematic.)

Pico's Nightmare (Winning without deaths. I did it multiple times.)

PinPunisher (Medals seem to unlock for some and not for others. I earned a few medals many years ago so I cannot tell if they would work for me now.)

SCGMD4 (A bug stopped awarding the chievos in-game. I tried with ANALYSIS PARALYSIS and PREMATURE ARTICULATION in a new save on my new computer but it was the same. Even if it would work I would only be able to get LET THE RIVERS RUN RED! ANALYSIS PARALYSIS and PREMATURE ARTICULATION and LET THE RIVERS RUN RED! takes too long for me to try again with. The other medals require you to play before 6 in the morning and I get my internet at 6, or basically perfecting the hardest song which is too hard for me. Yes I overkilled every boss on pro for nothing.)

Sky Kitty (Seems like both medals and highscores are problematic and only submit sometimes.)

Stinky Toilet (Big Green Shit)

Tankmas ADVENTure 2024 (Not really borked, but is made for machines much more powerful than anything I have. I could load and play it until late December when there simply was too much content put in.)

Testafan (Deadpool and Scorpion. The highscores and medals for the secret mini stopped to work for me all of a sudden. Since it stopped to work so suddenly I assume it works for others.)

The Curvature Project: Expanded Show (True Deity Spell Caster)

TOM FULP CLICKER (Average Tier!)

Other problematic medals

These are medals I know how to get but the requirements are different from what is told or you need a specific browser or such. This is the section I know potentially could be the largest, but I know I cannot find all games I have played and forgotten that could fit here.

Abducted by Aliens 2 (You have to click on new instead of play at the beginning for Sleep!)

Abducted by Aliens 3 (You have to click on new instead of play at the beginning for Escape!)

Awesome Ranger (RANGER and SUPERHERO cannot be earned together.)

Falling Platformers (Boss. Click on your character while you play. Falling 5000 meters earns you nothing.)

Hidden Valley Ninja (Weapon Master. You cannot craft Shadow's Edge as the last weapon. It must be a collectible.)

It Came From Outer Space (Firstly, you need to allow unsecure content with a browser that could allow it. I think all chronium based browsers block this. Firefox could allow it. Secondly, you need to go to credits, press backspace and delete to reset save file and reload the page for each play. Some medals do not work at all.)

Jet Pack Jesus (You can play on phone, but you need a keyboard to it in order to get all medals.)

Kitty Pot Cracker Worlds (You need to allow unsecure content with a browser that could do this.)

MechaRay (You can play on phone.)

Memory Station β (The game turns gray when you complete a level. To get this to work you need to allow unsecure content with a browser that could do this. I think all chronium based browsers block this. Firefox could allow it.)

Nothing To Hide (Same as above.)

Platform Boredom (Same as above two. Otherwise the game freezes for a while when you reach 9000 points for the first medal.)

Qoosh (You need to play it with the Opera browser. It actually works to launch in Newgrounds Player if it is launched from that browser.)

Railroad Shunting 2 (E-Zone. You don't need to complete the whole zone.)

Runnin' Dude (You have to die at least once for You beated the game! or you will get Didn't die.)

Sonic Adventure X Ep.2 (The Leonardo fight is sadly unplayable. You have to cheat. I don't think this cheat should be accepted but in this case it is nessessary. Play in Newgrounds Player and open settings for flash player. Secondary click on a drop-down menu and click on forward a bunch of times. Yes you can cheat the scores in the whole game which I did.)

Super Bunny World (You need to unblock unsecure content in your browser. You could do this with Firefox.)

TDR RPG: The Quest for Xirang (Same as above.)

Ultimate Walnut Tapper (The medal pop-ups work, but not the medals. If you want the medals, you probably need to play it in the Firefox browser and refresh the game when you have reached all requirements. The game starts over, but somehow the medals insta-earn so there must be a save for them that the game finds.)

Wasted Youth, Part 1 (You need to unblock unsecure content in your browser. You could do this with Firefox.)

Other notes:

API disconnecting: After a while you cannot earn medals/submit highscores on Newgrounds. It is usually after around 90 minutes but it waries between games and how fast they run on your computer. Unity games are usually short lived and disconnects after ~20 minutes while flash games almost always work for hours and should not disconnect until six hours or so.

Gamezhero games and similar with that preloader cannot load in Newgrounds Player.

Newgrounds Player has a save issue: For some games it can load saves but not save.

It is possible to use old flash in the browser on Newgrounds. You need the flash player and a browser that supports it. You can enable original flash for games in Newgrounds settings by disabling both Ruffle and Newgrounds Player.

Some tricks or cheats/ways around mentioned for specific games could be tested for other games, such as enabling blocked content in the browser or using hidden forward and backward buttons in the flash settings.
