The key for level 13-7 of DragonScales 3 is to form a way to access the pink scale on the left side at the bottom. Our approach starts by removing the rocks surrounding the central arrow, identified in Figure 1. Remember: to remove rocks just form combinations in adjacent cells.
After removing the rocks, activate the arrow (Figure 2.)
Now focus on the 2 adjacent arrows, on the top row (Figure 3). Activate one of them.
The next step is to activate the bomb to break the block (Figures 4 and 5).
Finally, activate the arrow to lower the column and get access to the pink scale (Figure 6.)
All that remains is capturing the cross pink scales and getting 80 scales of any color.
There are two tricky scales in Level 9-8 (see Image 1.) For both scales the key is to setup the required scales beforehand in order to form the match/combination exactly when the arrows are activated. To remove scale Tricky 1, first we have to place golden scales in the near tiles. When the two arrows are activated we should have already placed the golden scales we need, and the combination is done after the last of the two bottom-left arrows is activated.
For instance, in Image 2, we have already managed to place two regular golden scales near to the goal golden scale we want to remove (Tricky 1.) Images 3 to 8 only show a few of our plays to activate the arrows. But the important thing is that the 2 golden scales are already in the right place.
Regarding the scale labeled in Image 1 as Tricky 2: we have to follow a similar procedure. See Image 9. Just manage to place golden scales in the proper tiles, and then keep playing to activate the remaining arrow. See Images 9 to 11.
It’s fairly simple once you’ve figured the order in which scales should be removed. You’ll also need a bit of good luck with the scales you’ll get to play! 🙂
