Holy Grail System

The Holy Grail system was born among friends during long nights at Las Vegas casinos. We named it that way because many times it saved us at the roulette table. It is especially useful when combined with other systems and when you have enough capital. If the system fails, it’s best to walk away from the game—it's probably not your night.

Rules

Observe the numbers coming out on the roulette wheel.

Write down the last 18 different numbers that have appeared. If a number repeats, count it only once.

Once you have 18 unique numbers, bet 1 chip on each (total: 18 chips per spin).

If you don’t win on the spin, repeat with the same 18 numbers.

When you win and make a profit, end the game. Do not continue risking those winnings.

Practical Example

Let’s say the following numbers have come up:

6, 16, 7, 34, 31, 23, 25, 18, 24, 25, 3, 13, 35, 10, 0, 10, 2, 23, 4, 25, 34, 35, 19, 32

From those, select the first 18 unique numbers:

2, 3, 4, 6, 7, 10, 13, 16, 18, 19, 23, 24, 25, 31, 32, 34, 35, 0

Now you place 1 chip on each.

• 1st spin: number 30 hits → no win → loss of 18 chips
• 2nd spin: number 4 hits → win → you recover the bet (net profit: 0 chips)
• 3rd spin: number 3 hits → another win → total profit: 18 chips → end the game

Final Tips

• This system is low risk and offers quick results.
• It is not necessary to increase bets, although in a losing streak, a small increase could help recover.
• Exit the game when you’ve made a profit. If you want to keep playing, consider starting with a new bankroll.
• The Holy Grail system often generates profits within the first 1 or 2 spins, making it ideal for short sessions.
