QuickCalc rewards fast answers, but a wrong tap has two consequences: it breaks your streak and costs either a life or time. Improving a run therefore starts with identifying the operation before touching an answer. The calculation and scoring examples below are constructed teaching examples, not screenshots of today's Daily course or a recorded player result.
Start QuickCalc in Classic if you want time for each question, or choose a 30-second duel for a short shared course. You can tap an answer or use keys 1–4 for the four displayed choices. A key selects a position, not a fixed number: always read the new choices.
The mode changes the cost of a mistake
| Mode | Starting allowance | Wrong answer |
|---|---|---|
| Classic / Daily | 3 lives; a timer per question | Lose 1 life; streak resets |
| Time Attack | 120 seconds | Lose 3 seconds; streak resets |
| Duel | 30 seconds; no hints or extra time | Lose 3 seconds; streak resets |
Classic and Daily allow 10 seconds on questions 1–5, 8 on 6–10, 6 on 11–15, and 5 from question 16. Wrong answers leave you on the same problem while resetting that question's timer if you still have a life. In timed modes, mistakes do not skip a difficult question either. Repeated guessing can consume the whole clock without advancing.
Worked example: read the multiplication first
Two-step expressions can appear from question 16. Consider this valid example of that question type. The choices are shown in one possible order; they are not permanent keyboard assignments.
12 + 3 × 4 = ?
| 1 | 2 | 3 | 4 |
|---|---|---|---|
| 21 | 24 | 27 | 40 |
- Notice the × before calculating from left to right.
- Calculate the multiplication: 3 × 4 = 12.
- Add the remaining 12: 12 + 12 = 24.
- Find 24 among the choices. Here it is position 2, so either tap it or press 2.
The wrong calculation is (12 + 3) × 4 = 60. That inserts brackets the question does not contain. If your mental answer is absent, recheck the expression instead of choosing the closest visible number. The good check is to point out the multiplication, finish it, and only then match the result to a button. This example produces an exact integer; no rounding is involved.
Operator questions ask for a symbol
From question 11, some questions hide an operator. For 7 ? 3 = 21, select ×. The alternatives do not fit: addition gives 10, subtraction gives 4, and division does not give 21. You are selecting an operation, not selecting the number 21. Outside duels, the operator hint can reduce the choices to two; a separate timer hint adds five seconds once per round. Duels disable both kinds of assistance.
Why protecting a streak changes the score
For a correct answer, the base is 100 × difficulty phase: 100, 200, 300, or 400. Add 50 times the current consecutive-correct count, including the answer you just got right. Classic and Daily also add a bonus based on remaining question time. A correct operator question doubles the resulting total. Time Attack and Duel do not add that remaining-time bonus.
Here is a controlled duel example. You reach question 11 with four consecutive correct answers since your last mistake, then answer an operator question correctly. Your streak becomes five. The award is (300 + 5 × 50) × 2 = 1,100 points. If you first choose a wrong operator, three seconds disappear and the streak resets. Correcting that same question then makes the streak one, for (300 + 1 × 50) × 2 = 700 points. Previous points are not subtracted, but this question awards 400 fewer points and you have less time left.
That comparison is why repeatedly tapping options is costly. It does not prove that waiting indefinitely is best: the timer still runs. Aim for one checked calculation, then one deliberate selection, rather than a particular tapping speed.
Send a fair, understandable friend challenge
Finish a duel and share its result to send the course link. The shared seed fixes the question sequence and answer positions, and both attempts start with 30 seconds without hints or time boosts. Replaying that link lets you practice the same course; starting a fresh challenge makes a new one.
The result in the link is self-reported. This is an asynchronous challenge, not a verified live leaderboard. For a useful comparison, agree whether replays are allowed and compare the same link in the same mode. A friend may reach fewer questions if they spend longer calculating; that does not mean they received a different starting course.
One last calculation
In a duel, question 6 is an ordinary numeric problem and your correct answer brings the streak to three. How many points does it award?
Show the answer
Question 6 is phase two: 200 base points + 3 × 50 streak points = 350. There is no remaining-time bonus in a duel and no doubling because this is not an operator question.
