Getting Through Riddle School 4
Riddle School 4 is the fourth entry in Tom Fulp's flash puzzle series on Newgrounds. It's a point-and-click adventure where you solve a series of increasingly absurd riddles and puzzles to progress through a school setting. The game runs in a browser, no download required, though some people prefer to grab the files and run them locally via a flash emulator since the original plugin is dead. I ran into a specific issue early on that most walkthroughs skip over. In the classroom scene, there's a puzzle involving a projector, a slide, and a mirror. The game doesn't tell you that you need to click and drag the slide onto the projector first before the mirror becomes interactive. I spent about twenty minutes staring at the mirror thinking it was broken. Once you interact with the projector and load the slide, the mirror suddenly responds. That's one of the core mechanics of this game - the order of operations matters and the game rarely signals what order to do things in.
Riddle School 4 Walkthrough Key Puzzles
The game is divided into sections that take place in different areas of the school. You move between rooms by clicking through doorways. Each room contains multiple puzzles that must be solved in sequence or sometimes simultaneously. In the first major area, the science classroom, you need to collect several items to proceed. There's a chalkboard with a math problem that looks like gibberish until you notice the numbers correspond to dates on a calendar in the same room. Write down the dates, figure out the pattern, and input it into the lockbox. A common mistake is trying to solve the math problem as actual arithmetic. It's not a calculation puzzle. It's a substitution cipher disguised as math. The locker combination puzzle appears later. You'll see graffiti on a few lockers with symbols. Those symbols map to a chart you can find hidden in the gym. Don't skip the gym section even if you're in a hurry. The chart is the only legitimate way to decode the lockers. There is no shortcut. I tried memorizing the symbol patterns and got them wrong twice before just copying the chart properly.
One counter-intuitive thing about this game is that inventory items often need to be combined before you even realize they should be combined. You'll pick up two seemingly unrelated objects and use them on completely different puzzles before the game registers that they go together. If you have items in your inventory that feel useless, keep them. Combine everything in the inventory menu before moving to the next room. This alone probably saves two hours of backtracking for most players. The final boss puzzle is... unconventional. It doesn't play by the same logic as the rest of the game. You need to pay attention to the background details in the final room specifically - there are color-coded panels that correspond to music notes shown earlier in the game. Click them in the order of the notes, not the order they appear on screen. The visual layout is deliberately misleading. I've seen several walkthroughs get this wrong because the author played the note sequence in display order instead of musical order. Performance-wise, the game can be sluggish on modern browsers even through emulators like Ruffle. If puzzles feel unresponsive, close other tabs and give the emulator more resources. It's not a coding issue, just the overhead of running old flash through a JS translator. The game itself is fine. Your browser just needs to not be doing anything else.

For the full detailed walkthrough covering every single puzzle with exact coordinates and sequences, you can search for the complete Riddle School 4 Walkthrough on Newgrounds or the Flash Archive. Most of the quick guides online skip the edge cases I mentioned above, so don't be surprised if you hit a wall that their walkthrough says shouldn't exist.
