Golden Flash Of Prestige
Bonus Only, released on May 17, 2022 by GoldenRock, brings a sophisticated slant to the slots scene. It’s a 3 reels setup with 3 equally modest paylines, all displayed in a stylish golden environment that suggests a wealthy lifestyle. There’s no flamboyant background animation, but I think the sleek design still conveys that polished vibe many players appreciate. The main icons revolve around the biggest casino destinations and a diamond-shaped gem, along with a special dice symbol that helps you unlock the action.
The game pays strictly left to right on each of the 3 horizontal lines, but the base round doesn’t offer line rewards in the traditional sense. You place bets anywhere from 0.09 up to 180 EUR, which covers smaller bankrolls as well as bolder spins. On each spin, you either come close to forming the correct arrangement of bonus logos (Macau, Vegas, Monte Carlo, or the dice symbol) or see diamond symbols filling the reels. The top win potential stands at x1,750 your total wager, so there’s room for a decent haul if you can trigger enough bonus multipliers. Meanwhile, the sound effects and music feel slightly retro, but it fits the old-school mechanical approach. I find that the slot also works smoothly on mobile, so you can spin these reels on various devices without any weird layout issues.
Discover The Three Lines
The theme leans toward high-end casinos and exotic locales, giving a sense of big-money glamor. Visually, everything is streamlined: the reels appear in front of a golden facade, and the spin lever on the side jerks into action each time you press Spin. Unlike typical fruit or bar symbols, Bonus Only highlights major gambling destinations like Macau, Vegas, and Monte Carlo, which are your major triggers for the Bonus Game. The diamond gem basically acts as a filler, not awarding any direct returns.
With just 3 paylines, the mechanics might initially feel limited, but I would say it’s more about waiting to land the correct combination on a specific row. Each row is dedicated to a specific bonus. Line 1 is Vegas, line 2 is Macau, and line 3 is Monte Carlo. If you line up three of the same city icons, you head into that city’s board for bigger potential payouts. Alternatively, if a dice Scatter or dice Wild helps complete the trio, it can grant even more dice throws in the bonus. The basic layout might take a few spins to get used to, but once you see how each line is connected to a certain bonus, you might find it fairly straightforward.
Low Volatility And RTP Insight
Because Bonus Only is low volatility, you’ll probably see smaller wins fairly often once the bonus triggers. However, you might need patience if you’re hunting that bigger multiplier because nothing pays during the base game alone. I recommend a bankroll of around 50 to 100 bets to ensure you can ride out potential dry spells. Even though low-volatility slots typically yield more frequent small gains, the real highlight in this slot is the bonus portion.
From an RTP standpoint, the official figure stands at 96.21%. Personally, that’s near the industry sweet spot, so it shouldn’t drain your balance too quickly in the long run. GoldenRock typically provides a single stable version of its slots, so I have not seen any mention of adjustable/floating RTP for Bonus Only at various sites. I consider that a positive because if a slot had multiple RTP settings, players might end up on a less favorable version without realizing it.
Board Game-Style Bonus Game
When you land three matching city icons on one of the three lines, or a combination of city icons and the dice symbol that completes the set, you launch the Bonus Game. This is the entire focus of Bonus Only, which is why base gameplay offers no direct line wins. A separate board appears, themed around the triggered city: Vegas, Macau, or Monte Carlo. Each board is ringed with multiplier squares and some corner spots that yield no reward. You start with 2 dice rolls (4 if you use a dice symbol in the combo).
• Each time you roll, you move around the board clockwise, collecting multipliers as you progress. • Rolling doubles gives an extra throw. • Some squares grant additional dice rolls or special extras (like the Mystery feature, which can shift your position or give a multiplier boost). • The higher laps you reach, the greater the multipliers become. Monte Carlo typically carries the most lucrative top squares.
At the end of your dice rolls, the best multiplier you’ve passed (or landed on) is applied to your stake, which is how you earn actual payouts. If you manage to trigger multiple lines at the same time, you can play separate boards consecutively, potentially stacking your total winnings. The maximum overall payout is x1,750 your bet, so if you combine multiple boards in one session, you might boost your chances of reaching that bigger figure. Though it’s not as straightforward as normal spinners with line wins, I think it offers a unique, board-game flair that fans of novelty might enjoy.
Benefits And Drawbacks
Pros:
• No base game payouts means the bonus is the central event, and it can feel refreshing
• Three distinct boards let you experience varying multipliers
• 96.21% RTP is close to ideal, in my opinion
• Wild dice icon can grant extra rolls in the board round
• Scatter mechanics also help complete a trio for the bonus
Cons:
• No Free Spins for those who prefer that format
• Diamond filler symbols don’t pay anything, which some might find too empty
• It might take patience to line up the correct bonus set on a particular payline
