Remember the puzzle app game Subara City" It's a great point scoring puzzle app game.  Who Can Get Z from Ruijun Li is very similar. 

What's different"
In Subara City The objective is build up your houses into hotels and skyscrapers. Then merge the skyscrapers.
In Who Can Get Z, the objective is simply to get Z.

Both games are quite good and both will take a long time to play.
