🎲 Neighbour + Dozen Strategy Simulator
This simulator tests a flat betting roulette strategy that combines a
dozen bet with wheel neighbours around the last number that landed.
The goal is to cover the area of the wheel that just hit while also keeping a larger safety bet on the dozen.
How the Strategy Works
1️⃣ When a number lands (for example 22), the simulator immediately prepares the next bet based on that number.
2️⃣ A flat bet is placed on the dozen that number belongs to.
Example:
22 → 2nd Dozen → bet 1.70 chips.
3️⃣ At the same time, the simulator places 0.10 chips on the 3 wheel neighbours on each side of the last number.
This creates a 7-number wheel section bet:
- The last number itself
- 3 numbers before it on the wheel
- 3 numbers after it on the wheel
Each neighbour receives 0.10 chips, meaning:
0.10 × 7 numbers = 0.70 chips total neighbour coverage.
The total bet per spin therefore becomes:
1.70 (dozen) + 0.70 (neighbours) = 2.40 chips per spin
Win Conditions
- If the next spin lands in the same dozen → the dozen bet wins (2:1 payout).
- If the number lands on one of the 7 wheel neighbours → the straight bet wins (35:1 payout).
Because the last number itself is included in the neighbour section, repeating numbers can produce large payouts.
Loss Handling
This system uses a flat betting approach.
There is no progression.
After every spin (win or loss), the next bet simply uses:
- The dozen of the most recent number
- The 3 wheel neighbours on each side of that number

Purpose of the Simulator
This tool allows you to run thousands of simulated spins to study how the strategy performs over time.
It helps visualize bankroll swings, volatility, and the effect of combining
wheel section betting with dozen coverage.
Like all roulette strategies, the house edge still exists, but simulations help analyse variance and session behaviour.
