Discover the most popular roulette strategies and the most effective betting systems to manage your bankroll and maximize your chances of winning.

SYSTEM 300

300 System

The 300 System gets its name from the total amount bet in each round: 300 chips. It’s a strategy that combines broad coverage with a more aggressive portion of the bet placed on individual numbers.

How it Works

  • Bet 100 chips on the first dozen (numbers 1 to 12).
  • Bet 100 chips on the second dozen (numbers 13 to 24).
  • Bet 10 chips on each of 10 selected numbers from the third dozen (25 to 36).

Possible Outcomes

  • If a number from the first or second dozen hits:
    You recover exactly the 300 chips wagered. You neither win nor lose, and you can continue.
  • If one of the 10 selected numbers from the third dozen hits:
    You win 360 chips (35 to 1 plus your bet). Since you lose 200 on the dozens and 90 on the other 9 numbers, your net profit is 70 chips.
  • If one of the 2 unbet numbers from the third dozen or the zero hits:
    You lose the 300 chips wagered.

Approximate Probabilities

  • First or second dozen (24 numbers): 24/37 ≈ 64.86%
  • One of the 10 selected numbers in the third dozen: 10/37 ≈ 27.03%
  • Uncovered numbers (2 from the third dozen + 0): 3/37 ≈ 8.11%

Recommendations

This system can offer positive results if applied with moderation. It is recommended as a strategy to take advantage of a good streak and walk away after a quick win—especially if you hit one of the 10 individual numbers. A similar approach is used in Shaun’s System, aiming for fast profits without prolonged exposure.
