Whack-a-Mole

The original Whack-a-Mole machine was invented in Japan in 1975 by Aaron Fechter for Bob's Space Racers. It started as a carnival midway game and grew into one of the most recognized reflex tests in arcade history. The concept is simple: moles pop up from holes, and you hit them before they retreat. Research on reaction time and aging shows that fast-paced visual motor tasks can help maintain processing speed in adults over 60 (see the Salthouse 1996 study below). Our version adds golden moles, bombs, and a combo system on top of the classic formula. Click moles, avoid bombs, and chase a high score directly in your browser.

1. Press Start to begin a 60-second round. Moles pop up from a 3 by 3 grid of holes.
2. Click or tap a mole the moment it appears. Each normal mole gives 10 points.
3. Watch for golden moles. They appear rarely, stay up for a shorter time, and give 50 points.
4. Avoid bombs. Hitting a bomb costs 20 points. Let them retract on their own.
5. Hit moles in quick succession to build a combo. Each consecutive hit within 2 seconds adds 5 bonus points per combo level.
6. The game speeds up as time passes. Moles appear faster and stay up for shorter periods.

• The game lasts 60 seconds.
• A 3 by 3 grid gives 9 holes where moles can appear.
• Normal moles give 10 points. Golden moles give 50 points. Bombs subtract 20 points.
• Moles stay visible for 0.8 to 2 seconds depending on how far into the round you are.
• Clicking an empty hole costs nothing. There is no penalty for misses.
• Combo bonus applies only to normal and golden moles. Hitting a bomb resets your combo.
• Your final score saves to localStorage as your personal best.

• Keep your cursor centered over the grid. Shorter travel distance means faster reaction time. Aim for the middle hole and adjust outward.
• Prioritize golden moles over normal ones. They are worth 5 times more and disappear faster, so treat them as urgent targets.
• Train yourself to recognize the bomb shape before clicking. The black body and lit fuse are distinct from the brown and gold moles. A half-second pause can save 20 points.
• Build combos early. Hitting moles within 2 seconds of each other stacks a 5-point bonus per combo level. A 5-hit combo adds 20 bonus points on top of the base score.
• Use keyboard keys 1 through 9 as an alternative to clicking. Each key maps to a hole position. This removes cursor travel time entirely once you learn the layout.

• Memory Match: A different reflex and recall challenge where you flip cards to find matching pairs under time pressure.
• Simon: Tests sequence memory rather than raw reaction speed, but trains the same quick-response instincts.
• Tap to Fly: Another timing-based arcade game where each tap controls altitude and split-second decisions determine survival.

• Rounds are short. A full game takes 60 seconds, which fits any break.
• The difficulty curve is automatic. The game speeds up on its own, so you never feel stuck on an easy setting.
• Combos add a layer of strategy beyond pure reflex. Choosing which mole to hit first matters.
• The mix of normal, golden, and bomb targets keeps every round unpredictable.
