Combo
Clear more than three blocks in one match and you have a combo. Match four at once and it's a 4-combo, five is a 5-combo, and up from there. The bigger it is, the harder it hits, and some items pay out more the further you push it.
In detail
A combo is any match clearing more than three blocks, and the popup reads COMBO x4 upward. The bonus is 10 damage for every block past three, added to the base before the chain multiplier. Some items roll off match size as well, at a rate per block cleared, and only on the first link: Berserker Helm pays 3% on a 3-match, 5% on a 5-combo and 7% on a 7-combo, and chained follow-ups do not roll.
