One Minute, One Nan: Ranking Casino Games by How Easily You Could Explain Them Over a Cuppa

There's a reliable way to work out whether a casino game is actually simple or just pretending to be. We call it the Nan Test. The rules are straightforward: you get one minute, a cup of tea going cold, and your nan asking perfectly reasonable questions like "but why is that man shouting about a seven?" If you can't get the gist across before she's stirred in her second sugar, the game has failed.

It sounds daft, but there's a proper point underneath. Games that are hard to explain are usually games where it's hard to know what you're actually paying for. And if you don't know what you're paying for, your bankroll doesn't stand much of a chance.

The Passes-With-Flying-Colours Pile

Roulette, red or black. "I put a pound on red. If it lands red, I get two pounds back." Done in eight seconds. Nan might even approve of the arithmetic. The moment you start explaining dozens, columns and the green zero, you're on shakier ground, but the core bet is as clean as it gets.

Coin-flip-style bets in baccarat. Ignore the third-card rules entirely — nobody at the table understands those either. "You bet on which hand gets closer to nine." Nan will ask why the cards look like they've been torn, and honestly, fair question.

Blackjack, the friendly version. "Get closer to twenty-one than the dealer without going over." That's it. The splitting, doubling and insurance malarkey is where the minute runs out, and to be honest, plenty of regulars would benefit from skipping it too.

The Middle of the Road

Slots. You'd think these would ace the test. "Press the button, pictures line up, sometimes money comes out." Nan nods. But then she asks the killer question: "How much do you win?" And you're into paytables, ways-to-win versus paylines, volatility, and whether the wild expands. Modern slots look simple and hide a spreadsheet underneath.

Football accumulators. "I pick five teams to win, and they all have to win." Nan immediately spots the flaw — "so one bad result and it's gone?" — which is more insight than most acca insurance adverts manage. Simple to explain, brutal to actually land.

The Ones That Need a Whiteboard

Craps. Genuinely, try it. The shooter rolls, but which numbers are good depends on whether it's the come-out roll or not, and now everyone's betting on the person next to them. There's a reason craps tables sound like a riot — half the table doesn't know why they're cheering.

Slingo. It's slots. It's bingo. It's both. "You spin, numbers appear, you daub them on a grid, but some symbols are jokers, and there's a bonus ladder." Nan's tea is now stone cold and she's moved on to telling you about Margaret's hip operation.

Live game shows. "It's a big wheel, but there are multipliers, and sometimes the wheel lands on a bonus round where a different wheel spins." That's not a game explanation; that's a cry for help.

Why Any of This Matters

Here's the serious bit hiding under the whimsy. The easier a game is to explain, the easier it is to see the trade you're making: this much money in, these odds of getting it back. When a game takes five minutes and a diagram to describe, it's usually because the house edge is tucked away in the complicated bit.

That doesn't mean you shouldn't play Slingo or have a dabble on a game show — if you enjoy them and budget for them, crack on. It just means the games you can explain in a sentence are the ones where you'll always know roughly where you stand. When you're choosing where your twenty quid goes, clarity is worth more than novelty. Nan understood that instinctively. She also kept her money in a teapot, which is its own kind of bankroll strategy.
