A fairly straight-forward Achievement to unlock. Playing the Crazy 8 Slots, all you need to do is hit a win of 10,000 or more chips.
This can be fairly time consuming, or incredibly quick, depending on how much you're willing to throw on each spin. I'd played with lower bets per spins, but never hit any luck.
Abandoning the pragmatic approach, but deciding to take the approach of higher stakes = higher rewards, within 10 spins of betting 30 across 88 lines, I'd unlocked this Achievement.
