Well hard to say but easier to show. I should try doing youtube videos about tips and tricks.
A few basic things that may help you is to know is to learn to recognize L and T shape paterns to make star gems as they are the best route to go for high scores.
Beginners also need to try to concentrate on speed rather than making the perfect matches all the time as making rapid matches gives you bonus points. Making more matches means more chances for random cascades. A very important thing is to always look for a minimum of 2 matches you can make in advance so you don t get stuck looking for a new match everytime
Last tip i ll give you is to remember you don t have to wait for a cascade to end to make a new move. That s very important since it ll be the only way to get the highly prized blazing speed mode.
Also try to remember that the closer to the middle your matches are made, the more chances you have to get cascades and clear up the board. The worst part of a match is if you have your matches restricted to one of the upper corners and can only do one match at a time.
I can add you to my party and we would do non ranked matches so you can just watch me play. That way you d learn much faster. I m sure you could breach the top 50 easily. You d have an edge on everyone.
