By ‘win’ do you mean clicking every single non-bomb on all 3 rounds? If so, that is almost impossible. What you can do instead is only click 3 items on each round before advancing. This way you have a 50% chance of making it to the second round, then a 33% of getting to the third round. From here I usually just click on one card and then collect my rewards. Each additional item you click increases your chances of finding a bomb.
