Level 127 uses free-move chambers. If you cleared level 126, you should be familiar with them.
127 is one of the levels that can be completed in zero moves – that is, by using all free moves. There are 3 sets of 3x3’s, each with 6 stone blocks that must be exploded twice to complete the level. Each set also has 3 free-move chambers. Use the chambers to form flame gems, which can be moved freely in a zig-zag fashion along the diagonal from lower left to upper right and visa-versa. Position two flame gems, one in center of the 3x3 and one right next to it and match them for an explosion. Do this twice for each set of 3x3 and all 6 stone blocks will be gone. Then repeat for the other two sets of 3x3’s and the level will be completed.
Hope this helps.
