How to play
Type the number in the middle on your numpad and press Enter to move to the next line. The faded lines below are what comes next, so reading ahead keeps your hand moving.
- Under Content, choose numbers only, expressions with + − × ÷, or a mix of both. The Mode is either a fixed number of items (10, 20, 30, 40 or 50; 10 by default) or a timed test (30 seconds or 1 minute; 1 minute by default) that scores how much you type in that time. Any content works with the timed test.
- Higher difficulty means longer numbers and more decimals. Hard brings 7–8 digit numbers and four-term expressions. To set the number length yourself, pick 1–3, 4, 5–6 or 7–8 under Digits. In expressions, every term uses that length.
- Thousands separators are shown only to make numbers easier to read; you do not type them. × is the * key and ÷ is /.
- Under Options, turning decimals off gives whole numbers only. Switching the unit to dollars shows amounts like $1,234.56, and with decimals on you always type two cent digits. Skip the $ and commas: type only digits and the point. In expressions, the number after × or ÷ is a quantity, so it has no dollar sign.
- Different options keep separate best scores.
- Pick a sound (mechanical clicky, mechanical quiet, typewriter or soft pop) or turn it off. Key presses, finished lines and mistakes each sound different.
- Correct characters turn blue; wrong ones turn red with the expected character shown small above. Fix them with Backspace.
- Combo and score: finishing a line with no typos and pressing Enter adds 1 to your combo. From a 3 combo the gauge on the right fills, and at 10 you enter fever, which doubles your points. One mistake resets the combo to 0, even if you fix it before submitting.
- Every correct line adds whole points: key points (digit 1, point 2, operator 3) multiplied by speed, accuracy, combo and difficulty. The details are under How scoring works below. Best records are saved by score.
On a laptop without a numpad, the top-row digits and regular symbol keys work too. On a phone, tap the on-screen keypad. Want to warm up with real calculations? Try the online calculator.
Why learn the numpad
The numpad lets one right hand reach every digit, operator and Enter. It is faster and more accurate than hunting for the top-row digits with both hands, but until your fingers learn the positions it can feel slower.
- Accounting and bookkeeping. If you enter amounts into ledgers all day, typing speed decides when you go home, and a single wrong digit can make a big difference.
- Data entry. Stock counts, order numbers and invoice numbers: number-heavy data is where the difference shows immediately.
- Cashiers and retail. POS terminals and calculators use the same layout. Entering amounts without looking speeds up checkout.
- Certification exams. Save time on number entry in practical accounting and office software exams.
- Spreadsheets. Typing a number and pressing Enter to move down a cell is the same flow as this practice.
Finger placement
Rest your right index, middle and ring fingers on 4 5 6. The small bump on 5 lets you find the position without looking.
- Index: 7, 4, 1
- Middle: 8, 5, 2, /
- Ring: 9, 6, 3, decimal point, *
- Little finger: −, +, Enter
- Thumb: 0
At first, aim for 95% accuracy or better rather than speed. Once you stop looking at the keys, speed follows.
How results are calculated
KPM (keys per minute) is the number of correct keys per minute: correct digits and symbols plus the Enter you press to submit, divided by the time taken. Accuracy is the share of keys pressed correctly the first time, so a key you got wrong and then fixed still counts as a typo.
How scoring works
For every correct line, all of the values below are multiplied, rounded, and added as a whole number. A correct line is worth at least 1 point however short or slow it is; a line submitted with a mistake is worth 0. Scores never have decimals.
- Key points: digit 1, point (.) 2, operator (+ − × ÷) 3. The $ and commas shown on screen and the Enter you press to submit are worth nothing.
- Speed multiplier: typing the line at 150 KPM gives 1×; it scales with speed up to 2× at 300 KPM or more, and down to 0.5× at 75 KPM or less. Speed is measured from the moment you submitted the previous line to this line's Enter (characters + Enter). Reading the next line counts as real typing time; only the first line is timed from your first key.
- Accuracy: 1× with no typos, 0.5× if you made a mistake and fixed it. That also breaks your combo.
- Combo multiplier (based on the combo after submitting this line): 1× for 1–2 combo; from 3 combo it grows 5% per step, 1.05× at 3 … 1.35× at 9; 10 combo or more (fever) is 2×. Fever's 2× replaces the 5% bonus.
- Difficulty: Easy 1×, Normal 1.2×, Hard 1.5×. Dollar units multiply by another 1.1×.
For example, typing 1234 on Normal at 150 KPM with no typos gives 4 × 1 × 1 × 1 × 1.2 = 4.8, so 5 points. Best records are compared by score within the same options. Scores saved before the scoring rules changed are not compared with new ones, but your best KPM carries over.
People who use the numpad at work typically type around 150–200 KPM. If you are just starting, 60–100 is a normal place to begin.
FAQ
Pressing the numpad does nothing.
Click anywhere on the page once and try again. The numpad works even with NumLock off, but on some laptops you need to hold the Fn key for the numpad to work.
Where are my records saved?
Practice records are saved only in the browser you are using (localStorage). Only if you press ‘Submit to ranking’ on the results screen and create a nickname are that round's score and per-item log sent to the server and added to the ranking.
Do I need to log in to join the ranking?
No. Just pick a nickname. Save the recovery code you get on your first submission and you can continue with the same nickname on other devices. The ranking is weekly, compares the same settings only, and resets every Monday at 00:00 Korea time (KST). See today's and this week's standings on the ranking page.
Why don't I type the commas?
You don't type them in a calculator or Excel either. The commas on screen just make large numbers easier to read.
How do combo and fever work?
Each line without a typo builds your combo, and from 10 combo you are in fever, which doubles your points. Fever ends the moment you submit a line with a typo. The results screen shows your max combo, how many times you hit fever, and how long you stayed in it.
How is the score calculated?
For every correct line, key points (digit 1, point 2, operator 3) are multiplied by the speed multiplier (1× at 150 KPM, 0.5–2×), accuracy (half if fixed), combo multiplier (5% per combo from 3, 2× in fever), difficulty (Normal 1.2×, Hard 1.5×) and 1.1× for dollars, then rounded. A correct line is worth at least 1 point, and scores are always whole numbers.
Can I practice without decimals, or with dollar amounts?
Yes. In the options next to the keypad, turn decimals off for whole numbers only, or switch the unit to dollars for amounts like $120.50. If you often enter foreign payments or invoice totals, practice with dollars and decimals on. Each combination of options keeps its own best score.
Can I do the timed test with numbers only, or for 30 seconds?
Yes. Content (numbers, expressions, mixed) and mode (item count of 10–50, or a timed test of 30 seconds or 1 minute) are chosen separately. 30-second and 1-minute results and rankings are kept separately. Difficulty, digits, decimals and unit apply to every combination, and each combination keeps its own best score.
Is it free?
Yes, free and with no sign-up. Ads may be shown to cover running costs.
