Whack moles as they pop up from their holes. Test your speed and reflexes in this classic arcade game.
Whack a Mole is a 30-second reflex game played on a 3×3 grid of nine holes. An 800 ms interval spawns a mole into a hole picked with Math.random(), and each mole stays visible for a randomised 600 to 1,100 ms before dropping back down. Catching the mole is +1; on roughly 30% of spawns a bomb also appears in a different hole, and hitting that subtracts 5, with the score floored at zero. The clock, the grid and both scores are plain React state — the game makes no network requests and writes nothing to storage, so nothing about your play leaves the browser.
Open Whack-a-Mole on AltFTool — it loads instantly in your browser.
Press Start Game — the 30-second clock starts immediately and moles begin popping up on the 3×3 grid.
Click or tap the mole the moment it appears. Each hit is +1, and you have between 0.6 and 1.1 seconds before it drops back down.
Leave the red bomb alone — hitting it costs 5 points. When the clock reaches 0 your score and session best are shown, with Play Again to restart.
A one-second interval counts down from 30 and ends the round at zero, so every game is exactly the same length and scores are directly comparable run to run.
A bomb appears on about 30% of spawns and costs 5 points, so tapping every hole indiscriminately scores worse than aiming. The score is clamped at zero, so it never goes negative.
Each mole's visible window is re-rolled between 600 and 1,100 ms, so you cannot memorise a cadence — the target hole is drawn fresh from all nine each spawn.
The whole game is one client-side React component: no download, no signup, no server call, and no local storage. Your score exists only in the open page.
Press Start Game, then click or tap each mole the instant it pops out of one of the nine holes. A mole appears every 0.8 seconds and stays up for 0.6 to 1.1 seconds before dropping back down. Each mole you catch is +1. A bomb appears alongside the mole on about 30% of spawns — hit that and you lose 5 points.
30 seconds. A one-second interval counts the clock down from 30, and the round ends the moment it hits zero: the grid clears, your total appears under "moles whacked", and Play Again restarts a fresh 30 seconds.
Catching most of what appears is the realistic target, and the ceiling comes straight from the timing — a mole spawns every 800 ms in a 30-second round, so there are only about 37 chances to score. Once you are catching most moles, accuracy matters more than speed, because every bomb hit costs 5 of the points you already have.
No. Clicking an empty hole, or letting a mole drop back down on its own, costs nothing. The only penalty is hitting the bomb, which subtracts 5. The score is floored at zero, so it can never go negative — but a few bomb hits can wipe out points you already earned.
No — the best score is held in the page's memory for the current session only. It updates in the "Best" card whenever you beat it, but refreshing the page or closing the tab clears it. Nothing is written to local storage and no score is sent to a server.
It is free with no download, no account and no signup. The grid, timer, scoring and randomisation all run as a single client-side React component in your browser, and the page makes no network requests while you play.
Yes. Each of the nine holes is a standard HTML button in a responsive 3×3 grid, so a tap behaves exactly like a click and the cells stay square on small screens. Because they are real buttons, they also respond to keyboard focus and Enter.
Hitting the bomb subtracts 5 points from your score. It is drawn as a red bomb icon and appears on roughly 30% of spawns, always in a different hole from the mole — if the random draw picks the mole's hole, the bomb is shifted to the next one. Ignoring a bomb is free; there is no penalty for leaving it alone.
