On the level 220, we recommend that you focus on making power-ups – the more powerful, the better. This will allow you to quickly unearth gold nuggets and clear golden tiles. The most challenging part is detonating these power-ups in the right places.
We recommend you to not rush into detonating bombs and firecrackers after they appear. Instead, try to locate them closer to each other. This will clear out more space in less turns and will get you more bonus points for the Lightning power-up. It is also very useful to get two Lightnings and match them with each other.
