How do you get reward points in Mafia Wars?

• You get a free rp for each two levels you gain.
• You can buy mafia wars reward points.
• You can occasionally get free rp from:

1. Free slot spins daily (and bonus wheel)
2. Gold treasure chests (free key through daily take)
3. Mystery (&red) bags
4. email bonuses
5. Official zynga wall links
6. Secret drops

Exploits are rarely publicized and are completely against zynga terms. Even if you find an exploit (that doesnt give you a virus, via suspicious links), zynga may ban you.
