Debugging: Inside the Machine is a free debugging-practice arcade platformer for students preparing for AP Computer Science Principles or AP Computer Science A. You're inside a corrupted machine — find the USB Key, fix the glitches, and escape the firewall before the system collapses. CSP and CSA modes ship in the same app. Tap once to switch. — EASY · MED · HARD — Each difficulty is a different level, with its own glitch tilemap and its own question bank. CSP topics: Selection, Iteration, Functions & Lists. CSA topics: Variables · Strings, Iteration · Loops, Arrays · Recursion. Two bonus levels (K-Pop Demon Hunters, Minecraft) unlock when you've cleared all three difficulties. — CODE LENS — Glitches scatter across each level as collectible bugs. When you're in range, the CODE LENS button pulses on screen. Tap it and a real multiple-choice debugging question appears: read the broken code, pick the actual bug from four explanations, and the glitch repairs. Wrong answer? Stability drops 10 percent. Right answer? Stability recovers 5 percent and the level inches closer to stable. — Real questions, not filler — Every question is hand-written and scoped to AP exam topics. No random AI hallucinations, no off-curriculum trivia. The pseudocode reference card (CSP) and Java Quick Reference (CSA) are one tap away during any question. — Built for phones and tablets — Touch controls only. Bottom-left D-pad to move, big JUMP button on the right, hold for higher jump. Question screens use full-size answer buttons. Designed for landscape iPhone and iPad. — Offline, no account, no tracking — Everything ships in the app. The game makes zero network calls, collects zero analytics, and requires no sign-in. — More from CS++ — A "More from CS++" button connects you to the rest of the CS++ family: the AP CSP and AP CSA full-curriculum apps, the CS++ Java IDE for on-device Java practice, and the free csplusplus.com web resources (curriculum, vocab trainer, practice exams). For: AP CSP and AP CSA students, CS teachers building exam prep sessions, anyone who likes finding bugs.

BigFuture School's advantage is ratings volume (19K vs 4) and chart position (#3 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
