Diamond Boost by AGS is a classic type of slot that sticks to a simple but rewarding formula. The game pulls inspiration from old fruit machines, with three reels, bright sevens and bars, and a big focus on multipliers and jackpot prizes. Despite its retro layout, it has a few tricks tucked inside, including the Boost bonus mechanic that can increase paytable values as you go. If you enjoy slot games that keep things straight to the point, clean, and all about the spins, Diamond Boost might have what you’re looking for.
The look and feel of this slot are all about that arcade-style nostalgia. The reels sit against a deep purple background with bright lights and subtle sparkles, giving the whole setup a flashy yet old-school feel. Symbols are sharp and bold, featuring red, black, and white sevens alongside stacked BAR icons and classic multiplier badges. Every spin feels smooth, and there are a few modern touches like glowing outlines and crisp animations that keep it from feeling too dated.
Diamond Boost features familiar symbols that you would expect in a classic slot, but it adds a few extras that give it more depth.
Here’s a summary of the key symbols and their values, based on a max credit stake.

Wilds in the game can appear as either Diamond Boost logos or 2x Jackpot symbols. They substitute for standard symbols and also interact with bonus mechanics.
This is the main feature of the game and the one that gives it its name. It’s triggered when one or more Diamond Boost symbols land anywhere on the reels. Once active, it begins a hold-and-spin style bonus where the paytable values get progressively higher.
The red 2x Jackpot symbol acts as a multiplier wild. It substitutes for sevens and BAR symbols, and when part of a win, it doubles the prize. If two of these wilds are part of the same win, the multiplier goes up to 4 times the normal payout.
There are three tiers of jackpot payouts that can be won directly through line wins:
Only one jackpot prize can be awarded per spin, and it always goes to the highest possible outcome.
This slot uses a 3-reel, 3-row setup and allows players to select between 1, 3, 5, or 9 paylines. All wins are paid from left to right and must land on active paylines. You can adjust the bet per line independently, giving some control over the total stake. Line wins are multiplied by the bet per line.
There are no cascading reels or fancy grid systems here. This is a traditional spin structure, where clear symbols and straightforward wins keep everything easy to follow.
Diamond Boost stays close to its roots, and that’s actually what makes it work. It doesn’t throw in features just for the sake of it, and the Boost mechanic gives the base game a reason to hold your attention. The jackpots and wild multipliers can spice things up now and then, while the paytable scaling during the bonus offers a rewarding twist.
Players who enjoy online slots that do one thing well rather than trying to do everything will likely appreciate what this one has to offer.
