100-1 Roulette
Introduction
As far as I am aware, the 100-1 Roulette game is a unique offering from Draft Kings. It operates similarly to traditional roulette but is played on a wheel featuring 105 distinct spots where the ball can possibly land.
Rules
- The gameplay involves a wheel that consists of numbers ranging from 1 to 100, along with various symbols such as circle, diamond, triangle, star, and square.
- Here are the available betting options along with their respective payouts, where wins are presented on a 'to one' basis.
- Individual number of symbol — 100-1.
- Neighbors (two numbers) — 49-1
- Hat (three numbers) — 32-1
- Corner (four numbers) — 24-1
- First column (all five shapes) — 19-1
- Row or column (ten numbers) — 9 to 1
- The first two columns, which include five shapes and ten numbers, pay out at 11-2.
- Two rows/columns (20 numbers) — 4-1
- Odd/Even/Red/Black (50 numbers) — 1-1
Analysis
The following chart outlines the probability and expected value for all types of bets offered. According to the expected value column, the best bet is on any single number, which has a house edge of 3.81%, whereas the least favorable bet is on the first two columns (incorporating all five shapes and numbers 1 through 10) with a house edge of 7.14%.

| Single number | 100 | 1 | 0.009524 | -0.038095 |
| Two numbers | 49 | 2 | 0.019048 | -0.047619 |
| Three numbers | 32 | 3 | 0.028571 | -0.057143 |
| Four numbers | 24 | 4 | 0.038095 | -0.047619 |
| Five numbers | 19 | 5 | 0.047619 | -0.047619 |
| Ten numbers | 9 | 10 | 0.095238 | -0.047619 |
| Fifteen numbers | 5.5 | 15 | 0.142857 | -0.071429 |
| Twenty numbers | 4 | 20 | 0.190476 | -0.047619 |
| Red/black/odd/even | 1 | 50 | 0.476190 | -0.047619 |
Strategy
To minimize the house edge, it's advisable to place bets directly on individual numbers or shapes. It's worth noting that you can divide your bet into smaller bets on each specific winning outcome.
For instance, if you wish to place a $50 bet on red and win, you will receive $50 in winnings. However, if you place $1 bets on every red number, your total winnings would increase to $51.
