Five Ways to Build a Quiz in Sleedu Arena (and One Way to Bring Your Own Game)

I built Sleedu Arena because I wanted my chemistry students to practice the way they play: fast, competitive, and with a leaderboard on the projector. But none of that matters if writing the questions takes longer than the game itself. So the quiz maker gives you several ways in, from typing a few questions between classes to importing a whole unit’s worth in one click, and if you already have HTML games, there’s a way to bring those in too.

Before you start: what a question needs

Every question in Arena has the same parts:

• Type (multiple choice, select all, number, typed answer, put in order, or match)
• Question text
• Answers, in a format that depends on the type
• Explanation (optional, but worth it; students see it right after they answer)
• Image (optional)

Every game also gets a timer per question, a speed bonus for fast correct answers, and a Gradebook points value, which defaults to 100 so the score reads like a percentage in your gradebook.

Method 1: Type them in

Open the Games tab. The quiz maker is at the top.

1. Give the quiz a title, a subject, a unit, and pick the seconds per question. Twenty seconds suits recall questions; give calculation questions 45 to 90.
2. For each row, choose the Type and fill in the question.
3. The Answers box is one line, and the hint inside it shows the format. For multiple choice, list the choices separated by | with the correct answer first: Na | S | So | Sd
4. Click Add question for more rows, then Create game.

Arena builds the game, saves every question to your question bank, and shows the new game in your list. Check the periods that should see it, and it’s live.

Method 2: Let Arena’s AI draft them

Inside the quiz maker, open Generate questions with AI.

1. Paste your notes, a textbook passage, a worksheet, or simply a topic (“Naming ionic compounds, 10th grade”).
2. Choose how many questions, the grade level, the difficulty, and whether you want multiple choice only or a mix (adds select-all, number, and typed-answer questions).
3. Click Generate questions.

The drafts land in the table. Read them before you create the game. Delete the weak ones, tighten wording, and add an image where a diagram would help. Arena never sends student information to the AI, only what you paste, so don’t paste student names or work. Lite accounts get 10 generations a month; Premium gets 150.

Method 3: Use an AI you already have

If you’d rather draft in Claude, Gemini, or ChatGPT, use the Arena question prompt. It defines all six question types and asks the AI for explanations that teach: why the right answer is right, why the tempting wrong one is wrong, and a memory hook. The output pastes straight into Arena.

You are writing quiz questions for Sleedu Arena. Follow this format exactly.

TOPIC: [topic]
GRADE / COURSE: [grade and course]
NUMBER OF QUESTIONS: [12]
QUESTION TYPES TO USE: [mix of all types / or list specific ones: mc, multi, numeric, text, order, match]
DIFFICULTY: [easy / medium / hard]
MATERIAL (optional): [paste notes, a reading, or a worksheet here, or delete this line]

OUTPUT RULES
- Output ONLY the questions, one per line. No numbering, no headers, no blank lines, no commentary, no code fences.
- Every line has four parts separated by || in this order:
  type || question || answers || explanation
- Never use | or || inside a question, an answer, or an explanation.
- Questions under 25 words. Answers under 12 words. Plain, student-friendly language.
- Wrong answers must be plausible and similar in length to the correct answer.
- No "all of the above" or "none of the above." No trick questions.
- Base questions on the MATERIAL when it is given; otherwise use accurate, grade-appropriate content.

EXPLANATION RULES (students read this right after answering, so make it teach)
- 2-3 sentences, 25-45 words. Never just restate the answer.
- Sentence 1: WHY the correct answer is right, naming the rule, concept, or reasoning step behind it.
- Sentence 2: why the most tempting wrong answer is wrong, or the common mistake that leads to it.
- Optional sentence 3: a memory hook, real-world connection, or how to check the answer.
- Example: "Electrons carry a -1 charge and sit outside the nucleus. Neutrons are often confused with electrons because both are 'not protons,' but neutrons have no charge at all. Remember: electron ends in -on like negative ion."

THE SIX TYPES AND THEIR ANSWERS FORMAT

1. mc  (multiple choice, one correct)
   answers = choices separated by |, the CORRECT answer FIRST, then 2-3 wrong ones.
   mc || Which element has the symbol Na? || sodium | sulfur | silicon | selenium || Na comes from natrium, the Latin name for sodium. Sulfur is tempting because it starts with S, but its symbol is just S. Symbols from Latin names never match the English word.

2. multi  (select all that apply, partial credit)
   answers = choices separated by |, with * before EVERY correct one. Use 2-3 correct out of 4-5. Add "(select all)" to the question.
   multi || Which of these are noble gases? (select all) || *Helium | *Neon | *Argon | Nitrogen | Chlorine || Noble gases fill group 18 and have full outer shells, so they rarely react. Nitrogen is a gas but sits in group 15 and forms many compounds. Check the group number, not whether it is a gas.

3. numeric  (student types a number)
   answers = the number, optionally followed by a tolerance using ±. The question MUST state the unit.
   numeric || What is the molar mass of H2O in g/mol? || 18.02 ± 0.05 || Add the atomic masses: 2(1.008) for hydrogen plus 16.00 for oxygen gives 18.02. A common slip is counting hydrogen once, which gives 17.0. Always multiply by the subscript.

4. text  (student types a word; use a word bank in the question)
   Put a word bank of 4-6 options INSIDE the question, including at least two plausible wrong options.
   answers = every accepted spelling or form, separated by |.
   text || Word bank: proton, neutron, electron, photon. Which particle has a negative charge? || electron || Electrons carry a -1 charge and sit outside the nucleus. Neutrons are the usual mix-up, but they have no charge at all. Photons are light, not matter.

5. order  (put in order, partial credit)
   answers = 3-5 items in the CORRECT order, separated by |. Only one order may be defensible.
   order || Arrange from smallest to largest atomic radius || He | Ne | Ar | Kr || Each step down group 18 adds an electron shell, so the atom gets bigger. Students often reverse this by thinking more protons pull electrons closer, but that effect works across a period, not down a group.

6. match  (match pairs, partial credit)
   answers = 3-4 pairs written as left = right, separated by |. No = sign inside the items. Keep right-hand items short.
   match || Match the element to its symbol || Hydrogen = H | Oxygen = O | Iron = Fe | Gold = Au || Fe and Au come from the Latin ferrum and aurum, which is why they do not match the English names. Elements known since ancient times usually have Latin symbols. When a symbol looks unrelated, think Latin.

Now write the questions.

Method 4: Upload a spreadsheet or file

If you keep questions in Google Sheets or Excel, or you saved an AI reply as a text file, click Upload a file. Arena accepts .txt, .csv, .tsv, and .xlsx. Two spreadsheet layouts work:

Multiple choice only, one question per row:

Any type, one question per row:

The Answers cell uses the same | format as the quiz maker. A header row is skipped automatically. The file is read in your browser, so nothing is uploaded until you click Create game.

Method 5: Reuse what you and others already have

Every question you create is saved to your question bank, tagged with the subject and quiz title. Open Add from my questions, search or filter by tag, tick the ones you want, and they join the quiz.

Premium teachers can also share questions. Shared questions from other teachers lists them most-used first, so the ones that have worked in other classrooms rise to the top. Each use gives the author credit on their Plan tab.

Duplicate on any existing quiz opens a copy you can rename and edit, the fastest way to make a retake version.

Method 6: Bring your own HTML game

Arena isn’t limited to quizzes. If you have an HTML game already, made by hand or by an AI, it can report scores to Arena’s gradebook and leaderboard with a couple of small additions. You don’t need to edit code yourself; an AI can do it from a set of instructions.

Starting from scratch? The Copy AI prompt button on the Games tab gives you a prompt that produces an Arena-ready game in one go, for styles the quiz maker doesn’t do, like drag-and-drop matching, sorting games, or image hotspots.

The six question types, and when to use each

• Multiple choiceThe workhorse. One correct answer, up to three wrong ones. For true/false: True | False
• Select all that applyFor “which of these” questions. Star each correct answer: *He | *Ne | Na | Cl. Partial credit: right picks minus wrong picks.
• NumberCalculations. Give the answer with a tolerance: 18.02 ± 0.05. Say the unit in the question, because students type only the number.
• Type the answerSymbols, vocabulary, formulas. List every accepted form: sodium | natrium. Put a word bank in the question with a couple of distractors to keep it fair without giving it away.
• Put in orderSequences and rankings: H | He | Li. Partial credit for each item in the right place.
• Match pairsElement to symbol, term to definition: H = Hydrogen | O = Oxygen | Fe = Iron. Partial credit per pair.

Habits that make questions work in a game

• Short stems. Under 25 words. Students are reading against a timer.
• Wrong answers that could be right. “Sd” and “So” are better distractors for sodium than “Blue” and “Seven.”
• Match the timer to the work. Twenty seconds for recall, 60 or more for anything with a calculation.
• Write the explanation. It shows immediately after the answer, right when the student cares. Two sentences that explain the why beat one that restates the answer.
• Add an image when the question is really about the image. A structure, a graph, a lab setup.
• Preview before you open it. You’ll catch the typo in question 4 before your students do.
• Check the question results afterward. In the Gradebook, click a game’s title to see which questions the class missed. That’s tomorrow’s warm-up.
