Bonus Features Explained in Diamonds Up by Red Tiger
Let me explain how the bonuses enhance the gameplay in this one:
The Diamond Wilds appear on reels 2, 3, and 4, substituting for regular symbols to help form wins. More importantly, they're your ticket up the Symbol Upgrade Ladder.
Every 30 spins, a cycle forms, tracked by a counter above the reels. Land three Diamond Wilds and you move up one step on the ladder, which upgrades your lowest-paying symbols to the next tier up. Keep climbing, and those cherries eventually become sevens. Once the cycle of 30 spins ends, all of the symbol upgrades are reset, and you begin the process of upgrading them once again.
Land three or more Scatters to trigger the Free Spins as follows:
What's clever here is that your Ladder Progress carries over to the base game. This continuity makes the Free Spins feel like a natural extension rather than a separate mini-game. You can also extend this bonus by landing more Scatters. However, you can't land any Scatters if the last level of the Symbol Upgrade Ladder has been filled.
The Bonus Buy lets you buy the Free Spins with pre-filled upgrade positions. It'll cost you anywhere from 20x to 800x your stake, depending on how far up the ladder you want to start.

Win 20,000x Your bet in the Diamonds Up Video Slot!
It offers a Maximum Win of 20,000x your stake, not bad at all for a high volatility slot. The base RTP sits at 95.69%, which is slightly below average but not terrible. If you use the Buy feature, the RTP nudges up marginally to 95.7%. The high volatility means you'll have dry spells, but when wins land, they can be substantial. The hit frequency is 47.85%, which is very good.

Is Diamonds Up a Good Game?
Diamonds Up slot breathes fresh life into the classic fruit slot format. The 5 reels and 25 paylines provide a familiar framework, but the Symbol Upgrade Ladder is what makes this game worth your time. The 30 spin cycle concept is not new, but it makes sense because you can't have a game where the upgrades are permanent.
The Free Spins round can be interesting because the upgrades that you get in it are carried over to the base game. In short, it will move you up the ladder and help you unlock the big wins that seem elusive. You can also buy it, which is a good option.
In short, this is a simple, enjoyable, and profitable game that you should play.

Yes, you can! Dive into the Diamonds Up demo mode right here at BETO Slots. It's a great way to get familiar with the game's mechanics, features, and overall vibe without spending a penny.
The Diamond Wilds are a key part of the game, appearing on reels 2, 3, and 4. They not only substitute for all regular pay symbols but also help you climb the Symbol Upgrade Ladder. Collect three to upgrade the lowest-paying symbol.
If you're itching to jump straight into the action without waiting around for Scatters, the Bonus Buy option is just what you need. It lets you enter enhanced Free Spin rounds directly by investing multiples of your stake (ranging from 20x to 800x).
The Symbol Upgrade Ladder in this slot is a clever feature that spices up traditional gameplay by letting you enhance lower-paying symbols through cycles. With every set of three Diamond Wilds, you're moving up a step, potentially turning low-value cherries into valuable sevens.
Triggered by landing three or more Scatter symbols, the Free Spins round offers between 9 and 20 spins, depending on how many Scatters you've hit. During these Free Spins, any progress made on the ladder continues seamlessly to your base game cycle.
It is brought to life by none other than Red Tiger Gaming, known for its innovative and exciting slot creations. Their attention to detail shines through in this game with its mix of retro themes and modern features like upgraded symbols and bonus rounds that keep even seasoned players hooked.
