Sports betting explained: a primer before you bet
Spassino is primarily an online casino brand. Whether a sportsbook appears in your account depends on the operator's offer and on the country you sign up from, and we can't promise it will be there. So this section is not a sales page for a bookmaker. It is a plain explanation of how odds, margins and bet types work, written so that you can judge any betting offer — at Spassino or anywhere else — with a calculator rather than a hunch.
Is sports betting legal where you are?
In Slovenia, where this site is focused, betting counts as a game of chance under the Zakon o igrah na srečo (ZIS). Organising games of chance is an exclusive right of the state, exercised through concession holders licensed by the Government; the tax administration FURS supervises the sector, prohibits operating without a concession, and a court can order internet providers to restrict access to such sites. At the time of writing we could not confirm Spassino as a Slovenian concession holder — the list is public on the Ministry of Finance pages, so check it yourself. Outside Slovenia, your own country's rules apply.
A licence badge in an operator's footer tells you which authority issued it, not whether that authority's permission counts in your country. That distinction matters more than any odds comparison. We cover it in more depth on our Spassino review and on the responsible gambling page.
Reading decimal odds
European bookmakers almost always quote decimal odds. The number is your total return per euro staked, stake included. Odds of 3.00 on a €10 stake return €30: €20 profit plus your €10 back. Odds of 1.25 return €12.50, a profit of just €2.50. Dividing 1 by the odds gives the implied probability the price reflects — 3.00 means about 33%, 1.25 means 80%.
| Odds | Stake | Total return | Profit | Implied probability |
|---|---|---|---|---|
| 1.25 | €10 | €12.50 | €2.50 | 80% |
| 1.80 | €10 | €18.00 | €8.00 | ≈ 56% |
| 3.00 | €10 | €30.00 | €20.00 | ≈ 33% |
| 6.00 | €10 | €60.00 | €50.00 | ≈ 17% |
The bookmaker's margin
Add up the implied probabilities of every outcome in a market and you will get more than 100%. The excess is the margin — the bookmaker's built-in edge. A two-way tennis market priced 1.83 / 1.97 gives 54.6% + 50.8% = 105.4%, so the margin is roughly 5%. Main markets on big events tend to carry thinner margins; props, live markets and niche leagues usually carry thicker ones. Over hundreds of bets the margin is what grinds a balance down, which is why comparing prices matters.
The main bet types
- Match result (1X2 or moneyline) — who wins, with a draw option in sports that allow it.
- Handicap — one side starts with a virtual lead or deficit to balance an uneven contest.
- Totals (over/under) — the combined number of goals, points or games.
- Both teams to score — yes or no, regardless of who wins.
- Accumulators — several selections multiplied together; one miss sinks the lot.
- In-play betting — prices that move during the event.
- Cash-out — an early settlement option to look for in the rules; not every market has it.
Worked examples for each are on the bet types page.

If sports betting is available in your account
If the operator offers sports betting in your account, read the sportsbook rules before your first slip: how abandoned events are settled, whether extra time counts, what the maximum payout is, and how cash-out prices are calculated. Check whether sports bonuses carry separate conditions from casino bonuses — see bonus terms. Deposit methods and limits depend on your account, so check the cashier; our overview is on the payments page.
Decide a weekly budget and treat it as spent before the first bet is placed; winnings are a bonus, not part of the plan. Don't raise stakes to win back losses, and don't bet straight after an emotional result. If betting stops being fun, free confidential help is available from Gambling Therapy, and Slovenian residents can register a nationwide self-exclusion (samoprepoved) through eDavki — details on our responsible gambling page.
