Load-shedding mid-spin: what happens to a slot round when the connection drops

Anyone who has played on a phone in South Africa knows the moment: the screen freezes, the router lights go dark, and you do not know whether the spin counted. The question is reasonable, and the answer is more orderly than the panic suggests. This article explains what is generally true, what one regulator's published standard says about interrupted gambling, and a step-by-step routine for the minutes afterwards. It also says plainly what could not be verified.

How long a power cut can actually last

Load-shedding is the planned rotation of power cuts. When SABC News reported on Eskom's stage 4 schedules in June 2021, it explained that most load-shedding happens in 2-hour blocks, that blocks are 4 hours long in Eskom-supplied Johannesburg areas, and that each period has an additional 30 minutes added to allow for switching of networks. The arithmetic is worth doing, because it tells you what a recovery plan must cover: a customer on 2-hour blocks can be without power for up to 2 h + 30 min = 2.5 hours (150 minutes), and one on 4-hour blocks for up to 4.5 hours. Current stages and times come from Eskom and your municipality, not from this article. The point here is that a cut is rarely a blink. If you are in the middle of a bonus when it starts, you should assume you will be away for a long time, not seconds.

What happens on the server

An online slot is a client-server system. Your device shows the reels, but the casino's platform accepts the bet, records the round and updates the balance. That is why a dead battery or a dropped signal is not the same as a spin that never happened. What the platform does with an unfinished round depends on the operator and the game, and the operator's terms are the document that counts. The sources opened for this article do not include a studio rule from NetEnt, Playtech or Microgaming describing interrupted rounds, so none is quoted here.

What can be quoted is a regulator's benchmark. The UK Gambling Commission's remote technical standard RTS 10, titled “Interrupted gambling”, is a British rule that applies to operators licensed in Great Britain, not a South African rule. It is useful because it spells out what a fair policy covers. Its aim is that customers are treated fairly if play is interrupted and are told in advance how they will be treated. Its guidance for gaming includes these points:

• If the interruption happens after the gamble is registered and the customer can no longer affect the outcome, the result should stand.
• For a single-stage game interrupted before an outcome is generated, any deducted stake should be returned.
• For a multi-stage (stateful) game, the operator should take reasonable steps to restore the game to its last known state so the customer can finish it.
• Progressive jackpot values should be restored to their pre-failure state.

A basic spin on a slot is, in effect, the first case: the outcome is generated when you press the button, and nothing you do afterwards changes it, so a cut-off after that point should not change the result. A bonus with choices or a sequence of free spins is a multi-stage game, where restoration to the last known state is the standard the UK regulator describes.

Free spins and bonus rounds in progress

RTS 10 also says (requirement 10B) that systems must be able to recover from failures and keep enough information to restore an event, including items such as tokens collected and predetermined information such as prize layouts. For a player, the practical meaning is that a well-run platform should know how many free spins you had left and what you had won so far. Whether a particular casino resumes the bonus automatically when you log back in, or completes it for you in the background and credits the result, is a matter for its terms. No studio or operator wording on this was opened for this article, so it is not described here.

A routine for the first ten minutes

1. Do not retry the same bet at once. Wait until the connection is stable, then reopen the game. The game may return you to the unfinished round or show its result; that depends on the operator.
2. Check the balance and the game history before anything else. Look for a round or transaction history in the account menu. Note the round or transaction number if one is shown.
3. Write down the basics while you remember them: the game name, the time you were cut off, your stake and what the screen showed last. If the game reloads with a different state from the one you remember, take a screenshot straight away.
4. Read the casino's terms on interrupted games. RTS 10 expects the operator to make its interruption policy available to customers, so look for it in the terms or the help section.
5. Contact support in writing if the balance does not match the history, or a bonus appears to be missing. Quote the time, game name and round number, attach the screenshot and ask for a written answer.

The South African position

The legal background matters for who you complain to. The National Gambling Board stated in a media release on 27 February 2026 that interactive gambling remains unlawful in South Africa unless authorised by national legislation, and it quoted section 11 of the National Gambling Act 7 of 2004, which says a person must not engage in or make available an interactive game except as authorised in terms of the Act or any other national law. In practice that means online casino slots reachable from South Africa are run by operators licensed in other jurisdictions, and the rules that govern a disputed round are the operator's terms and the licensing regulator's rules, not a South African board's. This article has not verified any South African regulation specific to interrupted online rounds, and it does not claim one exists. See the FAQ on whether online casinos are legal in South Africa.

Gambling is for adults aged 18 and over. If an interrupted session ends with you chasing a loss, stop and talk to someone. The South African Responsible Gambling Foundation runs a toll-free line on 0800 006 008, and you can SMS “HELP” to 076 675 0710.
