You’ve probably seen Key Master machines in malls or arcades, touting prizes like iPads, earbuds, and other pricey electronics. To play, you must navigate a key towards a specific keyhole by stopping the automatic movement by hitting a button. If the key goes in, you win the prize. The problem, according to the lawsuit, is that these machines are programmed to only allow players the ability to win after a certain number of player failures.
