Tool 04 — CPS Battle
CPS battle: two player click speed test.
A cps battle in split screen: Player 1 (cyan) and Player 2 (magenta) race the same countdown. Keyboard on desktop — F vs J — tap-to-play on touch. Winner takes the round; first to the match point takes the series.
Same timer, pure speed
Both players see the same 3-2-1 start and countdown ring. No reaction advantage, no lag advantage — the faster pair of fingers wins.
Practice vs Computer
The AI clicks at a human-like, slightly erratic pace on three difficulties. Practice rounds don't touch your Personal Best record — only real duels count.
Series tracking
Best-of-1, best-of-3 or best-of-5. Match scores and every round's outcome are saved to your history, with a running win/loss record on your Personal Best page.
Two player click speed test, click duel and click race
This is a two player click speed test first and a battle game second: both players get the same countdown, the same ring, zero reaction advantage — the faster pair of fingers wins the duel. The split screen makes it a battle you can watch live, with a relative progress bar instead of just two numbers. Race a friend over a best-of-3 series and let the match decide who's faster today.
On desktop, the duel runs on shared keyboards with the F and J keys; on phones and tablets, each player taps their own half of the screen. No opponent around? The AI mode throws a human-like, slightly erratic opponent at you across three difficulties. The game is free and needs no account — and only real duels land in your win/loss record, so AI practice can't inflate it.
About
About CPS Battle
CPS Battle is the competitive side of the site: a split-screen duel where two players race the same countdown to see whose clicks add up faster. On a shared keyboard it's F versus J — cyan versus magenta — with a single 3-2-1 start and a live relative-progress bar so both players can see the gap opening or closing in real time. On a touch screen, each side of the display is its own button.
It exists because click speed is a performance, and performance changes under pressure. A duel forces you to click with someone watching, at someone else's pace, and that pressure is exactly what training alone doesn't simulate. Beyond the head-to-head, the AI opponent clicks at a human-like, slightly erratic pace across three difficulties — useful when no one's around to practice against. Every real duel is saved to your Personal Best history with a running win/loss record; AI practice rounds are kept out of your record so practice can't inflate it.
Guide
How to run a Click Battle
- 1
Pick the format
Choose the round duration and whether the match is best-of-1, best-of-3 or best-of-5. Player 1 takes the F key (cyan), Player 2 takes the J key (magenta) — on touch devices each player taps their half of the screen.
- 2
Wait for the same start
Both players see the identical 3-2-1 countdown and countdown ring, so neither side gets a reaction or lag advantage. Clicking early doesn't count — the clock starts for both of you at the same instant.
- 3
Watch the gap, not just the numbers
Live scores and a relative-progress bar show who's ahead and by how much. Rounds come down to pacing — a strong finish can flip a match that looked decided halfway through.

Practice against the computer
Solo? Set an AI opponent on Easy, Medium or Hard and duel it. AI rounds don't touch your Personal Best record — only real duels count toward your win/loss and progress chart.
FAQ
Frequently asked questions
How does a click battle work?
Two players race the same countdown to see whose clicks add up faster. On a shared keyboard it’s F versus J — cyan versus magenta — with a single 3-2-1 start and a live relative-progress bar. On a touch screen, each side of the display is its own button. Both players see the identical start, so there’s no reaction or lag advantage.
Can I play against the computer?
Yes. When no one’s around, set an AI opponent on Easy, Medium or Hard and duel it. The AI clicks at a human-like, slightly erratic pace, so practice rounds feel close to the real thing.
Do practice rounds affect my record?
No. AI practice rounds are kept out of your Personal Best record so practice can’t inflate it — only real duels count toward your win/loss and progress chart.
How do I win a match?
Choose a format from best-of-1, best-of-3 or best-of-5, then race the countdown each round. The player with the most clicks wins the round; the first player to the match point wins the series. Match scores and every round’s outcome are saved to your history.
Can I play on a touch device?
Yes. On touch screens each player taps their half of the display, so two players can duel on a phone or tablet without a keyboard. The same countdown and progress bar apply.
