10+ blocks on Good Combo 
20+ blocks is a Great Combo
40+ blocks is an Super Combo
60+ blocks is a Excellent Combo
80+ blocks is a Mega Combo
100+  blocks is a Elite Combo
120+ blocks is a Roy Sowyers Combo
Hard mode is twice the blocks, medium is times 3 and easy it times 4 (40,80,160,240,320,400,480).

 and incredibly long combos are possible... on the harder levels, the board gets filled up much faster, gameplay is much slower and the experience isn't nearly as rewarding (for me, at least).

so how do you calculate them? It seems to be depended of the difficulty-level. Because on Easy (Ultra) I got a "great combo" for 120 blocks. Just before on Expert (Ultra) I got a great one for 13(?) blocks.

Each block you clear before bonus meter hits zero does two things:
1) Adds bonus to score
2) Adds 25 to bonus.
When bonus meter hits 0, bonus is reset to 100
