Divide By Sheep Free - Ads as Punishment?

In a world where the Grim Reaper is at large and you have to cut sheep in half with lasers all the while exercising your best maths skills, it's easy to think things can't get much better.

Well they can! The puzzle game Divide By Sheep, which is available on Android, iOS and Steam is now available on the first one for free... sort of. For when you don't want to splash out the £2.30 to buy it, tinyBuild, the developers have made a free version of the game that is monetised by adverts. BUT there is a pleasant little catch. Adverts are only shown when you make a mistake, or fail in the game. So if your Maths skills aren't up to scratch then you'll be watching all the ads. It's quite a novel way of doing things, perhaps the horror of advertising will cause players to focus more and hone their Maths prowess quickly.

Regardless, if you'd like to try (for free) your hand at saving the world by destroying sheep then you can grab it here.
