This is a cool problem! Can I increase the chances to pick a certain (random) number in a given range? Let's say I have 10 numbers from 1 to 10 and I wish number "3" to have 1,6x the chances to be picked. Till now I did this by creating 10 instances of every number in the range. If I wanted number "3" to have 60% more "luck" I created 16 instances of it instead of 10. Then I put all the instances inside an array and random pick inside the huge bowl. But Jeez this is freaking GAS EXPENSIVE! I can't afford to create 19 objects if I wish one ticket to be 1,9x luckier! I ended up with 0,15 ETH gas expenses at only 26 gwei. This can't be the way. Any cooler ideas, maybe based on pure Maths instead of phisical creation of stuff?
