Roll Some Heads

Difficulty: Easy-Medium

Roll Some Heads is an achievement unlockable on PC, iPhone, iPad, Android, Nook, and PS Vita versions of Plants vs. Zombies. It is worth ten points on Game Center. The player will know that they have achieved this achievement when a gold coin drops from a zombie after being killed.

Strategies
The easiest way to get this is to wait for a wave of zombies and then roll a Wall-nut at the lead zombie or preferably by leaving a few zombies from before the wave alive long enough to bounce a Wall-nut off of them, too.

The player will have an increased chance of achieving this in Wall-nut Bowling 2 because there are more zombies there. If they do it during a huge wave and in front of the Backup Dancer that's in front of a Dancing Zombie, three zombies will be instantly hit.

Note: Neither Explode-o-nuts or Giant Wall-nuts will count for this achievement, as using these will not give the player any coins or count as a combo.

Trivia

 * This achievement's name refers to the phrase "Roll Some Pins" in bowling.
 * The PS Vita version has two icons: the one of a Wall-nut, and another that is the Versus vs Versus icon.
 * This achievement and Attention Deficit have the same icon.
