Frequently Asked Questions

A top bet occurs when the estimated probability of an outcome is higher than what the bookmaker's odds imply. For example, if our model estimates a 60% chance of a team winning, but the bookmaker's odds imply only a 45% chance — that's a top bet. It is a statistical estimate, not a guarantee: the bet can still lose.

In the short run, individual bets carry a lot of variance — even a 75% favourite can lose on any given day. A bet's value is a statistical estimate based on probability theory, not a promise about the result. Even over many bets there is no guarantee of profit — so only stake amounts you can afford to lose, and use responsible gambling tools.

Expected Value (EV) is the average return you would statistically expect if a bet were placed many times under identical conditions. Positive EV (+EV) means that, by our calculation, the odds are higher than the fair price. It is an estimate — real results can differ significantly and are not guaranteed.

Closing Line Value (CLV) measures how much the odds shifted between when you placed your bet and when the match kicked off. If you bet at 2.10 and the market closed at 1.85, you took a better price than the closing market. CLV says something about the price you got — not about whether the bet wins, and it does not guarantee profit.

Our system continuously monitors odds across 40+ licensed bookmakers and compares them against our proprietary probability models. These models are trained on historical match data, team and player statistics, injury reports, weather conditions, and live market movement patterns. When the market odds are meaningfully higher than our model's estimated fair probability, the bet is flagged as a value opportunity and published to the platform in real time.

Top bets are typically surfaced within seconds of an odds movement at a major bookmaker. The window to act can be narrow — sometimes just a few minutes before the market corrects — so we recommend checking the platform frequently, especially in the 2–4 hours before matches begin. Pinnacle odds closing are particularly useful to watch as a benchmark.

We show bets where the bookmaker's odds are above the estimated fair price. The value percentage shows how big that gap is — a higher percentage means a bigger gap, not a more certain result.

Yes. Even a bet with a 70% estimated probability will lose roughly 3 times out of 10, and losing streaks are normal. No bet and no strategy guarantees profit — in the short or the long run. Only stake amounts you can afford to lose.

The platform currently covers football (soccer), basketball and American football across dozens of leagues and competitions worldwide.

We only show bets at bookmakers licensed in Bulgaria by the National Revenue Agency (NRA) — currently bet365, Betano and Inbet. Their licence details and a link to the NRA's official list are on the Supported Bookmakers page. Only bet with licensed operators.

The percentage is our model's calculated probability that the outcome occurs. A 67% confidence means our model believes the event happens in approximately 2 out of every 3 comparable scenarios. To verify the value, compare this against the implied probability of the bookmaker's odds — if our probability is meaningfully higher, the edge is real.

Both plans include top bets across all covered sports, low- and high-risk views, the best-odds bookmaker, the value percentage and estimated probability for each bet, and match statistics. Basic has a daily bet limit and a value cap; Unlimited removes both and adds priority support. Current prices and limits are on the Subscription Plans page.

TopZalog.com is an information service: we analyse bookmakers' odds, but we do not organise gambling, accept bets or hold users' money. In Bulgaria, bets may only be placed with NRA-licensed operators and only by people aged 18 or over. For specific legal questions, please consult a lawyer.

If you decide to bet, set a budget in advance that you can afford to lose, and stick to it. A flat stake (always the same small amount) is the simplest way to limit risk. Don't chase losses or raise your stakes after a losing run. More in the Betting Strategies guide.

If betting is causing you financial stress, negatively affecting your relationships, feels compulsive rather than strategic, or you find yourself chasing losses — please seek support immediately. We are committed to responsible gambling and provide resources through our Responsible Gambling page. You can also contact organisations like GamCare or BeGambleAware at any time, and you can self-exclude from any bookmaker through their platform.
