1. In classic type gaming, it’s always better for you to make your matches at the upper part of game field, because you don’t know what’s coming down next, and you may have no more moves to make, if you have matches remaining at the bottom, you are sure you have more moves to make!
But in second type, it’s better to make matches at the bottom, because the chance to make a combo is much more, and it can help filling the time bar sooner.
2. As you will lose time much faster if you click on the hint button in the action game, it’s better to forget it!
3. If you quit the game, it will automatically be saved, you don’t need worry, next time you come to play, you can continue your last game.
Each type is saved individually, that means for example if you quit classic and start action and then quit the game, next time you can continue both the classic and action games, if you continue classic, the action will remain the same and you have a chance to continue it any time.
