Wrongulator is a calculator that’s never right!
When you’re up to manage some mischief at the expense of devastating damage to someone, there’s no thinking twice. So the Wrongulator is one such device that appears to be a perfectly normal calculator, with a solar charger above, but ends up being something that can topple sales charts and mess with your soul, more than you head. It’s so evil that it manages to produce a wrong answer every time you go for some quick calculation. This evil charm may backfire brutally though, like all pranks.
It could also make some lose their minds, or worse, get people fired. So make sure you aren’t going for the vital damage.
