Bonus Features / Jackpots Bonus Only

Bonus Rounds: In this online slot, you’ll have three main bonus rounds of Vegas, Monte Carlo, and Macau. You can’t just land three same symbols anywhere on the reels for triggering their features in the three bonus rounds. There’s a specific pattern that you’ll need to follow. If you land three of the same symbols in top-horizontal, middle-horizontal, and bottom-horizontal rows, you’ll trigger the bonus rounds.

You’ll be taken to a new game board once you manage to activate the bonus round. On the new game board, you’ll get to play with two 6-sided dice. As the dice are rolled, you’ll use their values to move on the board in a clockwise manner. You’ll get the opportunity to go for an additional dice roll if both the dice show the same value when rolled.

Of course, there are certain differences between the three main bonus rounds. Each of these bonus rounds comes with four different laps that have varying multipliers. While the multipliers of Vegas can reach only up to 40x, the Macau multipliers can go up to 80x.

In the Monte Carlo bonus round, the multipliers can reach up to 400x. When you’re done with a Bonus round, you’ll get the overall bet multiplier. You’ll have a hit frequency of 1:15 for all these bonus rounds.

Red Dice Symbol: If the Red Dice symbol lands on the third position of any reel, you’ll get 4 dice rolls for that particular bonus round. The Red Dice symbol acts as a Wild in this online slot and helps make up the three symbols required for the bonus round.

Re-spin: You’ll be given an automatic respin if you land two same symbols on any of the two reels. The existing Bonus symbols will be locked in place and only the losing reel would spin.

For the player to travel across the board, they will need to roll the dice. The reward will be a multiplier, no win, an additional roll, or the ability to go either backward or forwards across the board, and it will be determined by where they land. A bonus roll will be given to the player if they roll a double.

You can click on the three horizontal lines on the bottom right to check out the game rules. Use the plus and minus arrows that appear on either side of the current bet to adjust your bet amount. You bet between 0.09 and 180.00 in the game. Above the spin button, you’ll find the autospin function.

At the lower right of the screen just beside the menu icon is the ‘lightning’ icon. You can use it to adjust the game speed. If you land on any of the 8 mystery positions on the board, you’ll get to choose a card. It will reward you with a multiplier of up to x10, a dice roll, or a move forwards or backwards.


The first game of its type, Bonus Only, is distinguished by the absence of base game rewards in favor of concentrating all of the return to the player potential inside the game’s three bonus rounds. Because of this, software developers can provide players with an excellent hit rate of 1 in 15 spins to activate a bonus feature. We are particularly thrilled about Bonus Only as a slot since it caters to a broad-reaching clientele ranging from low rollers to high rollers.
Bonus Only has a special format, but offers no payline wins. It has an RTP of 96.21% and a maximum win potential of 1,750x. You’ll be spending much of your time in the game losing spins with no triggers. It would make some players feel as if they’re going through a grind.

Fortunately, the graphics are good and the music adds some excitement to the gameplay. The star attraction of this game are, of course, the Bonus rounds. Through Bonus Only, Golden Rock Studios has tried to present something different.
