What laptop should I get and how could I earn money?

I'm a 13 year old girl and I really would like a laptop that can run games like Sims 3, Sims 3 expansions, Sims 4 and Minecraft. I don't know of any laptops and so I need some nice, smooth-running cheap laptop makes/brands (whatever. ). Also, how would I go about getting money for it. Me and my mum go to local bingo every Wednesday/Sunday night and she lets me have one ticket of each colour (4), so if I win anything I'm going to save up and she's allowing me to do so. But how else would I earn money?
