The biggest mistake a lot of Coin Master players make, is rushing through levels as fast as possible. The reason this is a mistake is all due to cards and card sets. When you first start to play, you barely notice the card collection in the bottom left of the screen. The game doesn't allow you to unlock them until around level 4, so new players don't realize how important and rewarding they can be in helping you to progress.
The most strategic way to progress in the game is getting to level 5 and staying there until you complete the first 22 card sets. This means that you start with the Pet collection and stay on level 5 until you get to and complete Sand Land.
There are two ways to get coin master cards the "easy way".
1. Stay on village 5 and complete the first 22 sets as I mentioned above or...
2. Stay on village 5 and complete the first 15 sets or so, and then start moving up 1 village at a time when the game starts to slow down on the amount of new cards it gives you. Try not to move above village 10 until you complete the Sand Land set.
Completing the first 22 sets on level 5
Pros
The biggest advantage of staying still until all 22 sets are complete is chest cost. When you first start the prices are:
Wood Chest - 2 Million
Gold Chest - 6 Million
Magic Chest - 12 Million
As you move up to new villages, the cost of each chest goes up. By staying on a lower level, you can buy chests for much cheaper.
Cons
If you don't have a lot of Coin Master friends who has coins for you to raid, you can find yourself lacking enough funds to even buy the cheapest chests. This means that you can be held back for weeks or months as you try to complete the early sets.
Since your not moving up villages, your cards will be locked, and you won't be able to ask friends to send a specific card. It will sit in your gifts section locked.
Either strategy works and soon you will be getting all the cards you want and need to get thousands of free spins and more.
