Quick answer

Sports betting means risking money on the result of a sports event. A bookmaker offers a price (the odds). If your prediction is right, you get back your stake multiplied by the odds; if it is wrong, you lose your stake. Bookmakers set their prices so that, on average, they make a profit.

The basic idea

Sports betting is an agreement between you and a bookmaker (a company that accepts bets). You choose an outcome, for example "Dynamos will beat CAPS United", and you put money on it. That money is your stake.

The bookmaker shows a number next to every outcome. That number is the odds. It tells you how much you get back if you are right. In Zimbabwe, bookmakers show odds as decimals, such as 1.50, 2.50 or 4.00.

  • If your prediction is correct, the bet wins and the bookmaker pays you your stake multiplied by the odds.
  • If your prediction is wrong, the bet loses and the bookmaker keeps your stake.

A simple worked example

Suppose a bookmaker offers these example prices for a Castle Lager Premiership match:

OutcomeExample odds
Dynamos win2.50
Draw3.10
CAPS United win2.90

You place $2 on Dynamos to win at odds of 2.50.

  • If Dynamos win, your gross payout is $2 × 2.50 = $5.00. That $5.00 includes your original $2, so your profit before any deductions is $3.00.
  • If the match is a draw or CAPS United win, you lose the $2.

What happens step by step

  1. You open an account with a bookmaker, usually with your phone number, and later verify your identity. See how to register with a bookmaker.
  2. You deposit money, often with mobile money such as EcoCash, InnBucks or O'mari.
  3. You choose selections and they appear on your bet slip (also called a betting slip).
  4. You enter a stake and confirm the bet. The odds are fixed at that moment for most bets.
  5. The event finishes and the bet is settled. The bookmaker marks it as won, lost or void, and pays any winnings into your betting balance.
  6. You can withdraw your balance back to your mobile wallet or bank, subject to the bookmaker's rules.

Single bets and accumulators

A single is one prediction on one bet slip. An accumulator (also called a multibet or "acca") combines several predictions on one slip. All of them must win for the accumulator to pay, but the odds are multiplied together, so the possible payout is bigger. That is why accumulators are popular in Zimbabwe, and also why most of them lose. Our accumulator guide explains the maths.

Where the bookmaker makes its money

Bookmakers are businesses, not charities. They set prices that add up to more than 100% probability across all outcomes. That extra amount is their margin, and it means that over thousands of bets the bookmaker keeps a share of all the money staked. Read how bookmakers make money for a worked example.

This is the most important fact in sports betting: the odds are set against you. Some punters win in the short term, but over time most people lose more than they win.

Common misunderstandings

  • "Big odds mean big chances." No. High odds such as 8.00 mean the bookmaker thinks the outcome is unlikely.
  • "I have studied the teams, so I will win." Knowledge helps you understand a match, but football is unpredictable and the bookmaker's margin still applies.
  • "Betting can replace a job." It cannot. Treat any money you stake as money spent on entertainment.
  • "The payout is all profit." The payout includes your stake (see the example above).

Betting in Zimbabwe

Gambling in Zimbabwe is regulated by the Lotteries and Gaming Board. You must be 18 or older to bet. Most online bookmakers operating here use US dollars and accept mobile money. Before joining any site, learn how to check whether a betting site is licensed and read is online betting legal in Zimbabwe?

Summary

  • You stake money on an outcome at fixed odds.
  • If you win, payout = stake × decimal odds; profit = payout − stake.
  • If you lose, you lose your stake.
  • Bookmakers build a margin into their prices, so betting costs money on average.
  • Only bet money you can afford to lose. Our bankroll management guide explains how to set limits.
