Bonus Only Slot

Bonus Only Slot Online

One of the most interesting things about the Bonus Only slot is the fact that it combines the concept of slots with a board game to create a really exciting experience. Although not very often, we’ve seen the concept of board games incorporated in other video slots before, such as Big Time Gaming’s Monopoly Megaways slot and the Snakes and Ladders Megadice slot by Pragmatic Play. As for the Bonus Only slot, it comes with unique gameplay where the main focus is on the bonus round.

About Bonus Only Slot

Being on the iGaming scene for only a few years now, Golden Rock Studios would still be considered a relatively young company. However, despite all of that, the developers have managed to leave a great impression on both players and operators by creating excellent, high-quality video slots. The studio seems to just be starting, so now let’s see what this latest release has in store for you.

The layout of the Bonus Only slot is among the simpler ones, as it consists of 3 rows, 3 reels, and only 3 possible paylines. Landing 3 matching symbols across each of the rows will result in a win.

Players can also select from a great betting range, which offers options for both high rollers and those who prefer smaller stakes. The lowest bet is set at £0.09, while the highest is capped at £180 per spin.

Design, Symbols and Graphics

In the base game, you get to spin the reels on a slot machine, which retains that original vintage feeling. The slot machine is blue and gold, decorated with interesting patterns and there is also a golden lever on the side too. Pressing the spin button is accompanied by immersive animations of the lever being pulled and there is also a great soundtrack to accompany this as well.

As for the bonus round, the layout changes to a board game, while the backdrop presents a depiction of a city, based on which symbol triggered it. Tall buildings and bright lights are part of the experience, which can be quite an exciting one. What’s more, the game also comes with sharp graphics that can make the whole experience more immersive.

In terms of symbols, the paytable is not very populated. First, the pink diamond is a non-winning symbol. It is followed by Vegas, Macau, and Monte Carlo symbols, where each one can only land on the first, second and third row, respectively. 

Finally, the dice symbol acts as the wild, which can substitute any of the rewarding symbols and trigger the bonus round. 

RTP, Variance and Payouts for Bonus Only Slot

This is a low volatility game, which means that rewards can land a lot more frequently, but they may not be very high in value. The maximum possible payout that can potentially be achieved in this game can reach up to 1,750x the stake.

The Bonus Only RTP is capped at 96.21%, which is a good above-average value.

Gameplay and Features on Bonus Only Slot

As we already mentioned, the title of the game perfectly describes it as well. Namely, prizes cannot be won in the base game and the only thing that you can do is trigger the bonus round.

Bonus Round Feature

Landing 3 matching bonus symbols across a single row will activate this feature. The feature begins with 2 dice rolls unless you trigger it with a wild symbol, in which case you will receive 4 dice rolls. Each position on the board has a multiplier value and landing on it will add that value to the win multiplier above.

There are also special question mark positions which allow you to choose a card that can reveal a multiplier, an extra dice roll, or how many positions to move forwards or backwards. What’s more, managing to land the same number of both dice will award you an additional roll.

After managing to make a full lap around the board, the highest multiplier will be added to all positions. The multipliers in the Vegas, Macau, and Monte Carlo bonus rounds can potentially reach up to x40, x80, and x400, respectively.

On the other hand, it seems that the animations in the Bonus Only slot are a bit laggy, but the sharp graphics and colourful visuals can more than make up for it. You can check out the Bonus Only demo at some of the casinos we offer here on SlotsWise.
