Betting Strategy: What Holds Up and What Does Not
Value betting, arbitrage, low-odds systems and staking plans, explained with the maths and the limits of each.
No betting strategy guarantees a profit, because every price a bookmaker offers already includes its margin. What a sound betting strategy can do is stop you overpaying for bets, keep your stakes in proportion to your bankroll and help you spot the rare prices that are better than they should be. This guide covers the approaches South African punters ask about most and is honest about where each one breaks down.
The margin: the number every betting strategy has to beat
Convert decimal odds into implied probability by dividing 1 by the odds. On a soccer match priced 2.10 home, 3.30 draw and 3.60 away, the implied chances add up to roughly 47.6% + 30.3% + 27.8% = 105.7%. The extra 5.7% is the bookmaker's built-in edge. Any plan that ignores it is simply betting with a small handicap on every slip. Our betting odds calculator works out implied probability and returns for you.
Value betting in practice
Value betting means backing an outcome only when you believe its true chance is higher than the price implies. If you rate a team at 55% to win and the odds are 2.10 (47.6% implied), that is a value bet; at 1.70 (58.8%) it is not, even if the team is the favourite.
The hard part is the estimate. A "value bet of the day" posted on a tips channel or a value bet finder app is only as good as the model behind it, and most do not publish their record. A simple value bet calculator only does the division above: the judgement is still yours. Keep a spreadsheet of your own estimates, the price you took and the result. After a few hundred bets it will tell you more about your edge than any prediction site.
Arbitrage betting and its catches
Sports betting arbitrage, or "surebetting", uses different prices at different bookmakers so that every outcome is covered and the combined stake returns a small profit whatever happens. It works on paper when the implied probabilities across the best prices add up to less than 100%.
| Step | Example (two-way market) |
|---|---|
| Best price on player A | 2.15 at one bookmaker (46.5%) |
| Best price on player B | 2.05 at another (48.8%) |
| Total implied | 95.3%, so a gap of about 4.7% |
| Stakes on R1,000 total | about R488 on A and R512 on B |
| Return either way | about R1,049 |
In reality the gaps are small and close within minutes, live arbitrage betting moves even faster, and one price changing before your second bet is placed leaves you with an ordinary one-sided bet. Bookmakers can also void bets placed at obvious pricing errors under their terms. A free arbitrage bet finder or an arbitrage betting app can show you the gaps, but cannot stop those risks. Treat "free arbitrage bets today" lists with suspicion.
The 2 odds and 1.10 odds strategies
The 2 odds betting strategy aims to combine selections into a bet at around evens and repeat it daily. The 1.10 odds strategy backs heavy favourites at very short prices, often rolling the winnings over. Both feel safe because they win often. The maths says otherwise: at 1.10 you need to win more than 9 bets in 10 just to break even after the margin, and one upset can wipe out a long run of small wins. Rolling winnings over makes that worse, because the final bet carries everything.
Football betting strategy: where real edges come from
The best football betting strategy is usually narrow rather than clever. Punters who follow one league closely, such as the Betway Premiership, can sometimes judge team news, fixture congestion and travel better than a bookmaker pricing hundreds of matches. Specialise, compare prices across several licensed bookmakers before every bet and avoid long accumulators, where the margin multiplies with each leg. See our guide on how to bet for the basics of markets, and the best betting odds page for comparing prices.
Staking plans and mathematical betting strategies
- Flat staking: the same small share of your bankroll on every bet, for example 1-2%. Dull, and the most reliable way to survive losing runs.
- Kelly-style staking: stake in proportion to your estimated edge. Mathematically efficient if your estimates are right; punishing if they are not, which is why many use a fraction of it.
- Martingale: doubling after every loss. A losing run quickly demands stakes far beyond your budget or the bookmaker's maximum bet. Avoid it.
Greyhound and keno strategies
Greyhound betting strategy follows the same logic as horse racing: form, trap draw and price comparison. Keno is different. It is a pure number draw, so keno strategies cannot change the odds of a ticket; choosing more or fewer numbers only changes the shape of the payout table. The same applies to lottery-style games and slots: no system improves a random draw.
Keeping strategy in proportion
Gambling is for adults 18 and over, and it is not a way to earn an income or recover losses. Set a monthly budget, use the deposit limits licensed bookmakers provide and stop when it is spent. If betting has stopped being fun, the responsible gambling page lists free help, including the National Responsible Gambling Programme line on 0800 006 008.
Questions and answers
Is there a betting strategy that always wins?
No. Every price includes the bookmaker's margin, and results are uncertain. A strategy can reduce how much you overpay and control your stakes, but it cannot guarantee a profit.
Is arbitrage betting legal in South Africa?
Placing bets with licensed bookmakers is legal, and no law bans covering every outcome. Bookmakers can, however, limit accounts and void bets placed at clear pricing errors under their own terms.
What is a value bet?
A bet where you believe the true chance of the outcome is higher than the probability implied by the odds. It depends entirely on how accurate your own estimate is.
Does the 1.10 odds strategy work?
It wins often but pays very little, so you need to win more than nine bets in ten just to break even. One upset can cancel a long run of small wins.
