Maybe we could put together a complete table of all combo levels on all difficulty levels...
Anyway, AFAIR,
130 blocks on Easy is a Great Combo,
199 blocks is a Super Combo,
241 blocks is an Excellent Combo,
352 blocks is a Mega Combo,
410 blocks is an Elite Combo
(these are not the minimum values, though).
;)
BTW, IMO playing on easy is much more fun than anything else, because there's a huge lot of stuff going on all the time

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).
