贪吃蛇

Classic Snake gets a quiz layer that turns aimless arrow-key collecting into structured review. Steer your growing snake toward apples. Every 5 apples triggers a question pulled from your uploaded material. A correct answer earns +2 bonus points and keeps the snake moving smoothly. A wrong one costs momentum and puts your run at risk on the next near-miss.

The thing that makes Snake work as a study tool is the second chance. If your snake crashes, into a wall or into itself, the game offers one last question. Get it right and you continue from where you fell. Get it wrong and the run ends. So even a crash becomes a chance to learn. The game asks you a question right when you most want to keep playing, and your knowledge decides whether you do.

Golden apples show up rarely and are worth 5x points. They also trigger a harder question, which sharpens the score-versus-difficulty tradeoff. Chasing one is genuinely riskier, both because the snake usually has to detour and because the question that follows asks more of you. Those risk-reward calls are what keep Snake interesting once the novelty wears off.

Snake is the most universal of the action games on StudyQuest. Almost everyone has played a version of it, the controls are immediate, and the early difficulty is gentle. That makes it a good way in for students who've never tried a study game. Attempts run 5-12 minutes, which is about how long most students will give a study tool before deciding whether to come back.
