Gambling comes in many forms, but two of the most popular are sports betting and slot machines. Both attract millions of players worldwide, but how do they compare in terms of profitability?
This case study will analyse 100 sports bets and 100 slot machine spins using a controlled experiment to determine which option provides the best return on investment (ROI) and which presents the highest risk.
Methodology
To make this a fair comparison, we applied the following parameters:
Sports Betting Parameters
- 100 bets placed, each for £10
- Markets: Match winner (1X2), handicap betting, over/under
- Odds range: Between 10/11 and 6/4
- Sports included: Football (Premier League), Rugby, Cricket, Tennis
- Betting Strategy: Focused on line movements, statistical analysis, and value betting
- Data Source: Odds from multiple UK bookmakers to ensure best pricing
Slot Machine Parameters
- 100 spins on a high-volatility slot
- Bet size: £10 per spin
- Slot RTP (Return to Player): 96%
- Bonus Feature Rounds Activated: Yes, tracked separately
- Game Type: Classic 5-reel video slot with free spins and multipliers
The experiment was conducted in a controlled environment where every bet and spin was recorded. For the slots we used Bovada real money casino games and for sports betting we went with multiple bookmakers, based on who offered the best odds for the given play at that time. A win/loss analysis was done at the end.
Findings: Sports Betting vs. Slot Machines
1. Profitability Analysis
Betting Type | Total Wagered | Total Won | Profit/Loss |
Sports Betting | £1,000 | £1,210 | +£210 |
Slots | £1,000 | £930 | +£70 |
- Sports Betting: Out of 100 bets, 54 were wins. This resulted in a total return of £1,210, meaning a 21% profit on the original bankroll.
- Slot Machines: The theoretical RTP of 96% suggested a return of £960, but due to variance, our final return was £930, resulting in a 7% loss.
2. Win Rate & Expected Value
Category | Win Rate | Average Return per £10 Wager | Expected Value |
Sports Betting | 54% | £11.21 | +12.1% |
Slots | Varies per spin | £9.30 | -7% |
- Sports betting had a positive expected value (+12.1%), meaning that over time, a skilled bettor can be profitable.
- Slot machines had a negative expected value (-7%), consistent with the house edge.
3. Risk and Variance
Sports Betting Risks:
- Requires sports knowledge and research.
- Variance can be high in single bets.
- Odds may not always offer true value due to bookmaker margins.
Slot Machine Risks:
- Pure chance: No strategy affects outcomes.
- High volatility: Long losing streaks are common.
- House edge: RTP is always below 100%, guaranteeing losses over time.
💡Key Insight: Sports betting allows skilled players to reduce risk, while slots remain fully luck-based.
4. Case Study: Real-World Betting vs. Slots Session
To make this study even more relevant, let’s examine two real-world sessions:
Case 1: Sports Betting
- A bettor placed 100 bets of £10 each, carefully choosing value bets.
- Winning bets (54 out of 100) included a 6/4 underdog that won, boosting profit.
- Final bankroll: £1,210 (profit: +£210).
Case 2: Slot Session
- Played Book of Dead (popular slot with 96% RTP).
- Landed free spins twice, winning £120 and £85.
- Had a 50-spin losing streak where no wins exceeded bet size.
- Final bankroll: £930 (loss: -£70).
This shows that sports betting, when done strategically, can outperform slot machines.
5. Which is More Profitable in the Long Run?
Sports Betting Advantages:
✔ Skill matters – bettors can improve over time.
✔ Positive ROI is possible with proper strategies.
✔ Lower house edge (often below 5%).
Slot Machine Advantages:
✔ No knowledge required – anyone can play.
✔ Potential for massive wins (jackpots).
✔ Fast-paced action – higher entertainment value.
Long-Term ROI Comparison
Game Type | Theoretical ROI (Skilled Player) | Theoretical ROI (Casual Player) |
Sports Betting | +5% to +20% | -2% to -10% |
Slot Machines | -2% to -10% | -5% to -20% |
A skilled sports bettor can be profitable over time, while slot players are expected to lose in the long run.
6. Final Verdict: Which One is Better?
