10 Games Like Whack-a-Mole — Free Reflex Games Online

Whack-a-Mole (Mogura Taiji in Japanese, 1976) was invented by Aaron Fechter at his company Creative Engineering. It became a Universal Studios arcade staple. The format: timed tap-the-thing reflex game. Same DNA powers a surprising range of browser games. Here are 10 free browser games that scratch the same itch.

Why is Whack-a-Mole considered a brain training game?
Three cognitive functions are exercised: reaction time (the most-trainable cognitive metric — improvement plateaus at ~150-200ms for most people); visual scanning (tracking 9 possible positions simultaneously); decision making (skip the bomb? grab the golden mole?).
It’s the same skill set tested in human-benchmark websites — reflex tests, sequence memory, visual memory. Our brain-test games above explicitly measure these.
Why the term ‘whack-a-mole’?
Outside gaming, ‘whack-a-mole’ is now a metaphor for any unending fix-one-problem-another-appears situation. IT security uses it for malware (block one vulnerability, another emerges). Policy debates use it (close one loophole, another opens). The phrase entered Webster’s Dictionary in 2010, 34 years after the arcade game.
