Simple rules.
Serious questions.

The run

Every run is twelve multiple-choice questions split into four levels of three. Each question has four options and exactly one correct answer. Questions get harder as you climb, and there is no timer, so take your time.

Pick an answer, then press Lock in answer. Once it is locked in it cannot be changed. You will see whether you were right and a short explanation, then move on.

Choose your stakes

• Checkpoint Mode: clearing a level saves your place. If you get a question wrong after clearing level 1, you can retry once from your latest checkpoint. The level you failed is replaced with fresh questions, so the retry is a real second chance, not a memory test.
• Legend Mode: one wrong answer ends the run. No retries, just bragging rights.

Ask a friend

Twice per run you can share the current question and its four options with a friend over WhatsApp, text or any app on your phone. The answer is never included. A share only counts if you actually send it.

Your result

At the end you will see how many questions and levels you cleared. Your best clean run (one without a checkpoint retry) is saved on your device so you can try to beat it.
