Sports betting basics
Sports betting works differently from casino games. Instead of a fixed RTP set by a studio, the price of every bet is the odds a bookmaker offers, and those odds include a margin that favours the bookmaker. Understanding how odds and margins work is the most useful knowledge a bettor can have. This section explains the basics and then looks at individual sports and bet types. We do not know whether a particular operator, Urho included, offers a sportsbook, which sports it covers or what its odds are, so always check the operator's own site.
Decimal odds
Most European bookmakers show decimal odds. The number tells you the total return per unit staked, including your stake. Example: a €10 bet at odds of 2.50 returns €25 if it wins, which is €15 profit plus the €10 stake. Odds of 1.20 on a strong favourite would return €12 on the same stake. The lower the odds, the more likely the bookmaker thinks the outcome is.
Implied probability
You can turn decimal odds into an implied probability by dividing 1 by the odds. Odds of 2.50 imply 40%, and odds of 1.20 imply about 83%. This is useful because it lets you compare the bookmaker's view with your own. A bet is only worth considering if you have a good reason to think the real chance is higher than the implied one, and even then, results vary widely in the short term.
The bookmaker's margin
If you add up the implied probabilities of all outcomes in a market, the total is usually more than 100%. The excess is the margin. Example: in a tennis match priced at 1.90 for each player, each side implies about 52.6%, totalling about 105%. That extra 5% is how the bookmaker earns money over time. Margins differ between markets and bookmakers, and they tend to be higher on niche events and complicated bets.
Common markets
- Match result: which side wins, or a draw where draws are possible.
- Handicaps: one side starts with a virtual lead or deficit to balance the odds.
- Totals: whether the number of goals, points or games is over or under a line.
- Specials and props: individual events within a match, often with higher margins.
Live betting
Live, or in-play, betting lets you bet while an event is under way, with odds that change constantly. It is fast and can feel exciting, which is exactly why it carries extra risk: decisions are made quickly, and there is little time to think. Data feeds can also lag behind what you see on a stream. If you bet live, set a smaller budget for it and avoid chasing losses within the same match. Cash-out options, where offered, let you settle a bet early, but the cash-out price normally includes a margin too.
Staking and limits
Treat betting as paid entertainment, not as income. Fix a budget for a week or a month, keep each stake small relative to that budget and never increase stakes to win back losses. Accumulators and long-shot bets are tempting because of their big potential returns, but they lose most of the time.
