Simply, bet 10 coins until you win, bet 10 again, then 100. Do this repeatedly until you’re rich! You will likely need an initial investment of 20-30k gold to do this, but once you do you will never need to buy Qi coins again! This is an awesome trick and easy method of cheating the Casino. Any more Stardew Valley tricks out there? Let me know! This trick should work on both PC and console!
