A new game element is introduced on level 68 – double chains. To break them, you need to make two matches with the chained piece. The best strategy here is to make matches in the lower part of the field. This way the pieces in the upper part will fall down, making additional automatic matches. Bombs and other power-ups are also super effective on this level. Making combo explosions and charging the Lightning power-up as fast as you can is a great strategy as well.
