You can unlock this as soon as you finish the Flight School, which takes place at the airplane graveyard in the desert, and is part of the main storyline.

You'll get a call from Woozie, the blind Triad you helped out in San Fierro, who's taken up residence in the Four Dragons Casino at the south end of the strip in Las Venturas.

As soon as this happens, you'll have access to your first casino, and thus access to your first opportunity to unlock various gambling related achievements.

First, let's max your gambling skill to 100% to make getting the related achievements easier:

• Save outside the Four Dragons Casino and head inside
• Find the Video Poker machine on the left near the Wheel of Fortune which takes $10k bets
• Increase the wager to five times the stake value ($50k)
• Play the poker game repeatedly until you get the notification you've reached "Whale" level, which allows you to loan up to $1m from the casino
• Go back outside and save your game, to retain your maximum gambling skill

Now we can get on with the rest of the achievement!

How to unlock:

Head to the Wheel of Fortune, located within its own walled in area inside the casino. If the wheel on the left has a croupier by it, you can play! Now, place a few thousand dollars each on the $10 and above betting squares and spin the wheel. If it lands on one of the same values as the betting squares you placed your thousand on, then your achievement will unlock. Even if it shows a negative loss on the screen, you'll still unlock it, because the number on the screen shows you your total win/loss across all the squares you bet on. If you lose, either reload your save or simply try again if you have the cash to spare.
