"Last-hits" are one of the core skills in MOBA-style games like League of Legends and DotA; a player who can consistently deliver the final blow on an enemy minion will generate more income than his less-accurate counterpart. When you're at home, it's easy enough to train by firing up your MOBA of choice. On the move, however? Well, Android owners can stay sharp with this simple, yet clever app.
Developed by Leigh Jackson of Melbourne-based Flyleap Studios, the aptly-named Last-Hit Simulator is all about "getting good CS in mid lane". Which I realise has a vulgar ring to it, but I have it on good authority that "CS" stands for "creep score" -- the number of creatures you've killed -- rather than something unsavoury.
As you can see in the video, the idea is to time your attacks so that you're responsible for the coup de grâce. If you strike too early or too late, the game will pop up a message informing you of the fact. It even has a leaderboard so you can go head-to-head with other farmers. It's also completely free.
The game is modelled off of DotA, so it may be less relevant to those engrossed in other, similar titles. Nonetheless, it's a clever idea and much in the same vein as that MMO healing simulator on iOS, it's absurdly meta enough to be strangely compelling.
