Riddle School is a {{Newgrounds}} flash game series created by [=JonBro=] following a boy named Phil Eggtree trying to escape numerous grades of school, and later on, a number of environments.

Upon release, the first game was met with positive reception, and requests for more games followed, with Jonbro obliging and creating Riddle School 2 & 3. After requests for a fourth got to be too much, Riddle School 4 was released as a joke. The day after, Riddle School 5 was released, which explained the fourth game's shortness and was supposed to have concluded the series.

Even though Jonbro had no plans to make more, he eventually gave in to fan requests and made Riddle Transfer, which was supposed to be the start of a SequelSeries. Unfortunately, Jonbro suffered creative burnout after that and cancelled all the games after Riddle Transfer 1.

!!Tropes featured include:
* AirVentPassageway: Very early on in [=RS5=], Phil sips through an air vent to escape his cell.
* AliensSpeakingEnglish: [[spoiler:Viz and Diz.]]
* AllJustADream: [[spoiler:[=RS5=] reveals [=RS2=] through [=RS4=] to have been this.]]
* ArtifactTitle: Past [=RS4=], the series has very little to do with school.
* BlindWithoutEm: Mr. Soggy in [=RS3=]. [[spoiler:You have to knock his glasses off with the rubber band hidden in the vent.]]
* BigBad: Viz.
** In Riddle Transfer, Zone 5.1 and its leader, Shaw DeLot.
* ChekhovsGunman: [[spoiler:Diz in ''Riddle School 4''.]]
* EndGameResultsScreen: Every game past ''3'' shows your completion time after the credits.
* EnterSolutionHere: In Riddle Transfer, you have to enter the codes on Phil and his friends' keypads to set them free. The codes are:
** Phil: [[spoiler:78255. You can see it by clicking on your TV screen.]]
** Phred: [[spoiler:51702. Phred's clue is a piece of paper with the word "Snoz". The letters are actually numbers, bunched up together.]]
** Zack: [[spoiler:12345. The clue he gives you sounds complicated, but it's actually a set of consecutive numbers. It was written on the side of his door.]]
** Smiley: [[spoiler:51333. The agent who locked her up was mumbling it to himself out loud.]]
* FinalExamBoss: [[spoiler:The dream chair]] in [=RS5=] is this in a sense, revisiting the beginnings of the previous three games with different goals: namely, instead of escaping each room you have to [[spoiler:kill your friends]].
* FourTemperamentEnsemble: Phil is choleric, Smiley is sanguine, Zack is melancholic, and Phred is phlegmatic.
* FreezeRay: [[spoiler:This is Viz's ultimate plan: to freeze the planets by harnessing Zack's coldness. Fortunately, it backfires on him thanks to Phil's intervention.]]
* TheGuardsMustBeCrazy: Apparently par for the course where Zone 5.1 (Transfer) is concerned. Not only do they make very little effort to conceal the codes to open the prison cells from the prisoners (see EnterSolutionHere above), but every guard in the facility apparently gets the day off at the same time.
** To be fair, having the prisoner know the code to his or her cell door is slightly less of an issue when they can't see or reach the dialpad.
** The staff in the schools Phil has gone to aren't much different. In [=RS2=], [[spoiler:Phil enters the principal's office, takes the key to the front door, and bolts... all ''directly in front of the principal'', who ''just stands there the whole time'']]. In [=RS3=], [[spoiler:the principal is too busy playing video games to notice as Phil swipes the key.]]
* HighSchool: The setting of [=RS3=].
* HoistByHisOwnPetard: [[spoiler:Viz's defeat]] in a nutshell.
* JuniorHigh: The setting of [=RS2=].
* LeaningOnTheFourthWall: In [=RS5=], shortly before the final series of puzzles in the game (and by extension the entire original series), [[spoiler:Viz says "Prepare yourself... for the Grand Finale."]]
** Similarly, during the introductory cutscene to Riddle Transfer, Phil makes a comment about a "new beginning".
* MythologyGag: The combination to Richy's locker in [=RS3=] is "BLOBBLES". [[spoiler:It's actually 53788078. Read it upside-down.]] Blobbles is the name of the protagonist of some early Flash animations [=JonBro=] made.
* NiceJobBreakingItHero: If Phil hadn't [[spoiler:escaped school early on the day he had way back in [=RS1=]]], the entire series's overarching plot would've been nullified.
* PaintingTheMedium: [[spoiler:The aliens]] have colored speech bubbles that match their skin color.
* ThePollyanna: Smiley to a T.
* SelfDeprecation: Several jokes in the series involve the impossibility of Riddle School 4 being released, even within ''Riddle School 4 itself''.
* ShoutOut: Too many to list, to other popular users, games, and animations on {{Newgrounds}}.
* SpaceWhaleAesop: [[spoiler:Stay in school.]]
* StockNessMonster: One of the five animal residents of Zone 5.1 (Transfer) is [[AddedAlliterativeAppeal Messie, the Mock Mess Monster]].
* StuffedIntoALocker: Richy in [=RS3=]. It's not at all clear how he actually got in there in the first place; maybe he did it to himself by accident.
* TertiarySexualCharacteristics: Smiley has a ''mouth'' as her characteristic. As a style choice, [=JonBro=] made all the children bald and gave all the adults hair. Since Smiley didn't have the usual TSC of hair, he tried giving her a mouth instead. It didn't work: The special features section in ''Riddle School 5'' lists "Smiley is a guy" as the biggest misconception about the series.
** Come Riddle Transfer, Smiley did indeed get hair.
* WellIntentionedExtremist: [[spoiler:Viz. Technically, he ''was'' trying to eradicate evil. He was just a little misguided about where he could find it.]]
* [[WhamEpisode Wham Game]]: Riddle School 4, [[spoiler: when Phil Eggtree 'died'. Made originally as an April Fool's joke to convince others there will be no more Riddle School games, but years later made a few more, with [=RS5=] tying in the significance of the other four games, including #4]]
