Da Vinci Diamonds slot

Da Vinci Diamonds slot: quick facts

IGT is a Las Vegas company and counts Da Vinci Diamonds among its best-known slots, alongside Cleopatra and Wolf Run. As the name suggests, it pairs Leonardo da Vinci with gemstones, on a standard 5x3 grid with 20 lines. Its one big mechanical idea is tumbling reels.

How the features work in Da Vinci Diamonds

Tumbling reels

When a spin produces a win, the winning symbols disappear and new symbols fall into the empty spaces. If the new arrangement forms another winning line, that pays as well, and the symbols involved disappear again. The sequence continues until no new win forms. All of it counts as a single paid spin, so one stake can produce a chain of wins. Our cascading reels guide covers the same idea under its different names.

Six free spins

Three bonus symbols trigger 6 free spins. Tumbling reels stay active throughout, so each free spin can also chain several wins. Landing more bonus symbols during the feature adds extra spins, which can stretch the round past its starting six. The help screen gives the exact number of extra spins and where bonus symbols can land.

We don't quote how often tumbles chain or how often the free spins arrive. Those figures aren't in our checked data, and estimates from third-party listings aren't reliable.

Da Vinci Diamonds RTP: the cost of 94.93%

This is the number that matters most. At 94.93%, the house edge is 5.07%, noticeably higher than the 3.5% to 4% you see on many modern slots. Over the same stakes, that difference shows up in pounds:

Put another way, the average cost of playing Da Vinci Diamonds is about 45% higher than a 96.5% game (5.07 divided by 3.5). That doesn't make it a bad choice if you enjoy it, but you should know the price. Our page on whether a higher RTP slot is better weighs RTP against enjoyment.

Da Vinci Diamonds cost per hour at UK speeds

Slot spins in the UK must take at least 2.5 seconds, so the theoretical ceiling is 1,440 spins an hour. Tumble sequences add time, so real play is usually slower. Here is the average hourly cost at three paces:

Those are averages over a long run, and any real hour can be very different. The cost per hour page compares slots with table games on the same basis.

Da Vinci Diamonds on a £20 budget

• 10p a spin: 200 spins before wins come back; about £1.01 average cost on £20 staked.
• 50p a spin: 40 spins; same £1.01 average cost on £20, but a short session.
• £1 a spin: 20 spins; one tumble chain or the free spins can decide the night.

A volatility rating isn't in our checked data, so plan for results that can swing. Setting a loss limit before you start is a simple way to make £20 mean £20.

Da Vinci Diamonds max win: 5,000x

The cap is a limit on one spin, including its tumbles or feature, not something to aim for. It would need a long tumble chain or a strong free-spins round, and it is a rare outcome. Our explainer on max win caps covers what happens when a win hits the limit.

How to play Da Vinci Diamonds online

1. Open the game at a UKGC-licensed casino and check that the help screen shows 94.93%.
2. Set your stake; all 20 lines play on every spin.
3. Spin. Each spin takes at least 2.5 seconds and there is no autoplay at UK casinos.
4. After a win, watch the tumbles: winning symbols vanish and new ones fall in, possibly paying again.
5. Land three bonus symbols for 6 free spins, with tumbling reels still active.
6. Look for more bonus symbols during the feature to add spins, then review your net position.

Da Vinci Diamonds online in the UK

The game follows all of Great Britain's online slot rules: a £5 per-spin cap for players aged 25 and over, a £2 cap for players aged 18 to 24, a minimum 2.5 seconds per spin, and no autoplay, turbo or slam-stop. The slot stake limits and autoplay ban pages explain these.

The Commission's rules on game descriptions and the likelihood of winning (RTS 3) (opens in a new tab) require casinos to make game rules and return information available, which is why you can check the RTP before playing. Our RTP information rules page explains more. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players.

Da Vinci Diamonds verdict, myths and mistakes

• Myth: tumbles mean the game pays more overall. The RTP already includes every tumble, so the long-run return is 94.93% whether wins come in chains or singly.
• Myth: an old slot pays better because it has been around longer. Age has no effect; see are new slots better than old slots.
• Mistake: ignoring the RTP gap. Over £500 staked, the extra average cost against a 96.5% game is about £7.85.
