ROULETTE

THE ROULETTE TABLE

A roulette table is split into two zones: the number grid and the outside bets.

The number grid runs from 1 to 36, arranged in three columns and twelve rows. Each number sits in either red or black. At the top of the grid, alone in green, sits the zero — the house's quiet advantage on every spin.

Surrounding the grid is where the broader bets live. Long rectangular boxes let you back entire categories at once: red or black, odd or even, the low half of numbers (1–18) or the high half (19–36). Below the grid, three boxes cover the dozens — 1 to 12, 13 to 24, 25 to 36. Along the side, three more cover the columns.

What you can bet on:

• A single number — place your chip directly on any number, 0 through 36. Pays 35 to 1 if it hits.
• A color — red or black. Simple, almost like a coin flip. Pays 1 to 1.
• Parity — odd or even. Same odds, same payout. Zero belongs to neither.
• A dozen — back a third of the board at once. Pays 2 to 1.
• A column — same coverage as a dozen, different numbers. Also pays 2 to 1.
• Split, street, corner — you can also straddle the lines between numbers to cover two, three, or four numbers with one chip.

The dealer spins the wheel one way, releases the ball the other, and everything resolves in seconds. One number wins. Every bet on that number or its category pays out. Everything else is swept from the table.

That's roulette. The rules take two minutes to learn. The strategy debates have lasted centuries.

CORE MODEL

For any roulette bet:

WHEEL TYPES

COLOR BET EXAMPLE

Payout: 1:1. On a single-zero wheel:

On a double-zero wheel:

WHY BET TYPE DOES NOT FIX EV

Changing from color to dozen/column/straight-up changes variance, not the standard house edge.

Note: American roulette has one common exception, the five-number basket bet (0-00-1-2-3), which has a higher edge than other bets.

RAKEBACK ADJUSTMENT

If rakeback returns fraction r of house edge:

With 50% rakeback on qualifying Duel roulette play:

VOLATILITY / STD

Use win probability and net outcomes:

Single-zero examples:

Bet type can change risk dramatically even when house edge is the same.

WARNING

Strategies are methods of shaping your risk and payout profile, not ways to beat the house.

They can be used to:

• Smooth variance and generate more frequent, smaller wins.
• Increase variance to chase larger, less frequent payouts.

This means each wager has a negative expected value, or neutral when playing zero-edge, and changing bet sizes or betting patterns won't change that.

MARTINGALE STRATEGY

Increase bet size after losses (typically doubling) to recover all previous losses plus a fixed profit. This works extremely well until it doesn't and all of your bankroll is gone.

Bet size sequence: b, 2b, 4b, 8b, ...

Stop when a win occurs, then reset to base bet.

Martingale — Distribution Effect

• Very high win frequency.
• Many small profits.
• Rare but extreme losses (one big loss can drain your bankroll).

PAROLI (INVERSE MARTINGALE)

Bet sequence after wins: b, 2b, 4b, ...

Reset to base bet after a loss.

Paroli — Distribution Effect

• Lower win frequency.
• Many small losses.
• Occasional large wins.

MY STRATEGY

We all know casino odds are against you, but that does not mean you cannot win in the short run. The goal should be to maximize the likelihood of finishing ahead during your session.

For roulette, I recommend aggressive high-volatility bets, such as betting a single number instead of a color.

We can see the simulations here: Show simulation Duel Color vs Duel Specific Number, both with 50% rakeback, 1,000 rounds, and 100 simulations.

You can see how the color distribution concentrates in the middle, while straight numbers allow higher wins and bigger upside tails. If you are willing to risk bigger losses, it's the only way to win big and not let variance slowly eat you up
