While it ' s true that they probably would make more profit with the old method , the new method makes them a more healthy company because now they ' re self sustained . <| sep |> Didn ' t say it was illogical . Most things work left to right , and you are right in that they show you the first two . But , they don ' t unlock left to right , it unlocks 1 then 234 can come in any order . Regardless of how the game unlocks the first two and presents the system , from a UI design standpoint it ' s bad . You want to be getting the most information across in a simple way . OPs image does that , without creating noise , or additional text . It ' s a simple design that gives the user a clear understanding of how the system works , even if they have never used it before , which their current UI design does not . A good UI is one that doesn ' t need previous knowledge to understand how it works .
