A fast-paced whack-a-mole game that turns spotting prime numbers into a race against the clock, sharpening recall while pupils compete for the high score.

Whack-A-Prime takes the instantly familiar whack-a-mole format and turns it into sharp, repeated practice at one core skill: recognising primes at speed. Numbers pop up and disappear in seconds, so pupils can’t fall back on slow working-out — they have to know their primes, not calculate them. That instant-recall pressure is exactly what turns rote fact-recognition into genuine fluency.

The competitive layer keeps pupils locked in without any extra prep from you. Three lives mean one wrong tap won’t end the round, but three will — so accuracy matters as much as speed. A streak bonus rewards consecutive correct taps, and clearing a run of ten primes without a mistake levels the player up, with the spawn rate resetting slightly for a well-earned breather before the pace builds again. A saved high score means pupils are chasing their own best — and each other’s — round after round.

Fully customisable for any class or ability: adjust the number range, hole count, round length, and how quickly the game speeds up (from a gentle constant pace right up to an Expert ramp), so the same game stretches from an early primes introduction to a genuine challenge for your most confident mathematicians.

Runs entirely in the browser with no installation required, works fully offline once opened, and is completely GDPR-compliant — no pupil data is ever collected, stored, or uploaded. Ideal for a warm-up, a plenary, a chess club filler, or a five-minute reward slot on the IWB.
