Hundred or Nothing RTP and Wagering

Hundred or Nothing - RTP & Wagering

If you’re looking for a streamlined slot with basic rules and gameplay, you’ve found it. This is played on a traditional three-reel setup with one payline running through the centre. 

Each time you tap the ‘spin’ button, the reels roll and may or may not line up symbols across the payline. That’s all there is to the gameplay. 

Just one cash prize is available: the 100x. Apart from that, there’s nothing else to win (just as the title says). If you don’t land three 7 symbols on the payline, you can either stop playing or spin again.

On every spin, wagers start from £0.10. But adults aged 25+ in the UK can bet no more than £5.00 per spin, while players based elsewhere may wager up to £1,000.

Despite the small prize available, this game’s theoretical RTP is far below the 96% average at 92.55%. You might expect to see an RTP as small as this in a progressive slot game, not in a game with such a tiny maximum win.

On top of this, this slot is highly volatile, it could take a long time to line up the three symbols exactly.

Hundred or Nothing Symbols and Audio & Video Design

Everything about this slot is streamlined, including the visuals. The game is designed to look just like a traditional slot machine, and IGT has created an authentically old-school aesthetic.

The three reels shine like they would on a physical machine in a casino. Above the reels, the logo has an eye-catching retro style, as does the blue background. The paytable (such as it is) is visible at all times, showing the one prize available.

While there’s no music or sound between spins, an electronic tune plays each time you spin the reels. That reinforces the game’s classic realism and bare-bones approach.

As mentioned earlier in our Hundred or Nothing review, the only symbol on the reels is the 7. Three of these must land neatly on the payline to award a win. There are no Wild symbols (as there are no other symbols for them to replace), and there are no Scatters.

Hundred or Nothing Mobile Features

IGT has fully optimised this slot for mobile devices, and it works brilliantly on a smaller screen. The simple structure and basic rules make this ideal for playing on a smartphone. Not only is it easy to interact with on a mobile, but the virtual slot machine fits nicely onto a small screen, too.

Hundred or Nothing Bonus Features

There are no bonus features available in this slot. It focuses entirely on the core gameplay: spin the reels and try to land sevens on the payline. You can’t trigger any free spins, pick-and-click rounds, or respins.

Hundred or Nothing Final Thoughts

Hundred or Nothing has been designed for casual players looking for a basic, laid-back slot experience. It’s not meant for users who seek out the most dynamic new releases packed with features and massive prizes. 

But even if you tend to play more elaborate slots, this could still suit you if you’re in the mood for a quick and easy game. It might make for a refreshing change, especially when you don’t have time for a long gaming session.

Ultimately, Hundred or Nothing is a stripped-back slot with a below-average RTP and tiny max win. If that piques your curiosity, play the free demo to try it for yourself.
