Video: If you're well-stocked with LEGO, you can build yourself a working version of Whac-a-Mole that even keeps score. It might even be better than the original, because if you break it, you can easily put it back together.
Adding to the ever-growing list of amazing things you can build with LEGO's programmable Mindstorms EV3 toys, ManicMiners, designed and built by Mike Dobson, has players trying to whack eight little helmeted characters 50 times as they randomly pop out of LEGO tyres.
The game was built using eight LEGO Mindstorms motors, six colour sensors, a touch sensor and a pair of control units that display and track the score. You'll need a mastery of LEGO to figure out how to build one for yourself, since Dobson hasn't released building instructions as of yet. But think of all that trial and error as you perfect your own version as a way of building up some frustration to unleash on the unsuspecting final build.
