Clumsy Treefingers: Organicraft
Most puzzle games are about as much use to me as a cheesegrater rasping back and forth across my brain. It helps if they have a theme that appeals to me and Organicraft gets that part right. There's a plant on the right of the screen and a sapling on the left. There are two options for growth patterns at the top of the screen and at each branch you click on one. It should be so easy but, like a terrible interior designer, I am oblivious to patterns. Look at the screenshot - that's not a joke, that's my sincere attempt to solve the game's third level. Spotted at Indiegames, it's free, browser-based and you'll probably complete it in ten minutes. I probably never will.
