For SS, you have to stay ahead of the pumpkins and shoot. For the town shooting gallery, get use to the patterns and notice: you only have to move left and right. Hope that helps you; it was a little tricky at first but I got a hang of it and so can you.
Ya like Danigo92498 said for the shooting gallery in OoT and MM there is a patter to the what comes so you will be able to memorize it. It like 2 colored rupees appear here and here yada yada, so when you see the first one in each group you will know what comes next. After you know it it's an easy way to get rupees and prices. Good Luck!
