If you came to PC gaming from a controller, or you just switched keyboards, WASD feels wrong for a while. Your ring finger hunts for A, you overshoot corners, and the only place to practise is inside a match where every mistake costs a round.
I run KeyboardTester.click, a collection of free browser hardware tests. Last summer I added a small Pac-Man-style movement game to it. Over the past four weeks it has been the most-clicked page on the whole site from US Google searches, so I rebuilt it into five games, gave it honest key statistics, and wrote this post to explain what it does, how each game scores, and what its numbers can and cannot tell you.

What it is
One page, five games, one control scheme. You move with W A S D or the arrow keys. The trainer reads physical key positions (KeyboardEvent.code, not the printed letter), so on an AZERTY keyboard the same physical keys, Z Q S D, work without changing anything. Every game has four difficulty levels (Beginner, Intermediate, Expert, Advanced) and three speeds (Slow, Normal, Fast). P pauses, Esc returns to the menu, and there is a fullscreen button in the corner of the arena. On a phone or tablet you get an on-screen directional pad.
Nothing is uploaded. Personal bests and recent runs live in your browser's local storage, so there is no account and no public leaderboard.
The five games and how they score
1. Maze Chase (Classic or Dodge only)
The original game. Eat dots, avoid the ghosts, grab a power pellet to make ghosts edible for six seconds, and clear the level.
- 10 points per dot, 50 per power pellet, 200 per blue ghost eaten, 100 for clearing a level.
- Optional pickups: cherries 100, bananas 150, mangoes 250, balloons 300. A pickup disappears after ten active seconds, so skip it when the escape route is poor.
- Dodge only removes the dot objective and keeps the pursuit. It is the mode I use when I only want to practise routing and second exits.
- Two directions together move diagonally.
Your rank in Maze Chase comes from survival time, not score: Beginner, Amateur, Skilled, Expert, Master, with the steps at 15, 30, 60 and 120 seconds. A higher score does not automatically mean a higher rank.
2. Snake
Turn the moving snake with WASD or the arrows. Each food adds 100 points and one segment; a wall or your own tail ends the run. An immediate 180-degree reversal is not allowed, so you turn through another direction instead. Snake is the game that punishes mashing: tapping faster does nothing for you, planning the turn before the edge does.
3. Coin Sprint
A 60-second route challenge inside a fixed maze. 25 points per coin, and every five coins advances the level counter. Paused time does not use the limit. The goal is points inside the window, not survival, so it trains short clean routes and releasing a key before you overshoot.
4. Meteor Dodge
Free four-direction movement while meteors fall. Surviving adds 10 points per second, an optional star adds 100, and a collision ends the run. Your best is survival time. Watch the space around the player instead of chasing every star, and leave yourself an escape lane.
5. Direction Memory
Watch an arrow sequence, then repeat it with separate presses. Round one is one direction, round two is two, and each round adds another. A correct round earns 100 multiplied by the round number; a wrong direction or a ten-second input timeout ends the attempt. Group the sequence into small phrases instead of rushing the first press. Holding a key is not the same as pressing it again, which is exactly the habit this game exposes.
The key stats panel
When a run ends the trainer shows Key stats from this run. Here is what each line means and how I read it.
| Stat | What it measures | How to read it |
|---|---|---|
| Avg presses/sec, Peak presses/sec | Key-down events per second, average and peak | More is not better. Snake and Coin Sprint reward fewer, cleaner presses. |
| Avg key hold | How long a direction stays held | Long holds in Direction Memory mean you are holding instead of tapping. |
| OS key repeat rate | The auto-repeat frequency your operating system delivered while a key was held | This is an OS setting, not a keyboard property, and it is not a polling rate. |
| Two-key overlap | How often two directions were down together | Diagonals in Maze Chase and Meteor Dodge; usually accidental in Snake. |
| Direction changes | Number of direction changes in the run | Only compare within the same game, difficulty and speed. |
| Per-key usage | Presses per key for W, A, S, D and any arrows you used | A direction you avoid shows up as a low or zero count. |
A missed move does not by itself mean the keyboard is at fault. If one key feels unreliable, press it on the interactive keyboard tester and watch whether it registers. If a particular combination fails, try it in the keyboard ghosting test, which checks whether several keys register together.
A five-minute rotation
This is the routine I actually use, about one minute per game:
- Maze Chase: look for a second exit before entering a corridor.
- Snake: plan corners before you reach the edge.
- Coin Sprint: trace the shortest route to the next coin, release before you overshoot.
- Meteor Dodge: keep an escape lane and make small corrections.
- Direction Memory: enter clean sequences with separate presses.
Restart short attempts inside the minute, pause between games, and stop if your hands feel uncomfortable. Pick one thing to notice, such as fewer missed turns, rather than chasing every statistic. Keep the same difficulty and speed for repeat attempts so a faster setting does not disguise a change in your routing.
What it does not measure
I would rather say this plainly than let the numbers imply it:
- It does not measure electrical switch latency or key travel.
- It does not establish or guarantee a hardware polling rate. The OS key repeat rate is a different thing.
- It does not prove that a better Meteor Dodge time transfers to CS2, Valorant or Apex. It trains the hand movement in isolation, which is the point, but the transfer claim is yours to test.
If you want those separate numbers, the site has them as separate tools: a keyboard CPS test for raw presses per second, a keyboard polling rate test for browser-observed event frequency, a reaction time test for response to a signal, and an APM test for actions per minute. Each answers a different question, and none of them is a Snake score.
How it is built (for the curious)
- Vanilla JavaScript on a
<canvas>, no framework, no build step. Each game is a small module created through one factory with the chosen difficulty and speed. - Input uses
KeyboardEvent.code, so W/A/S/D and the arrows map to physical positions and AZERTY users get Z/Q/S/D for free. - Input is armed only after you click the game once. Until then the arrow keys scroll the page like normal, so the tool never hijacks scrolling on a page you are just reading.
- Personal bests are keyed by game, difficulty and speed (plus Classic/Dodge for Maze Chase) in
localStorage. Recent runs are grouped by game. - The fullscreen button is capability-gated: if the Fullscreen API is missing (iOS Safari), the button does not render. Esc inside fullscreen exits fullscreen and pauses instead of ending the run.
- The same partial renders in ten languages, so the localized editions share one engine and one set of rules.
Quick FAQ
Can I use arrow keys or an AZERTY keyboard? Yes. Arrow keys are supported, and WASD reads physical key positions, which corresponds to ZQSD on AZERTY.
What determines my personal best? Maze Chase and Meteor Dodge compare survival time; Snake, Coin Sprint and Direction Memory compare score. Bests are separated by game, difficulty and speed.
Are my results saved online? No. Bests and recent runs are saved in your browser's local storage. Another browser, a private window or cleared storage shows different records.
Can I play on a phone? Yes, with the on-screen directional pad. P pauses keyboard play, and paused time does not advance the game's active clock.
