Bonus Only Review

Golden Rock Studios are still among the newer kids on the block, so it’s no wonder that they want to prove themselves with releases like Bonus Only. What’s on offer here is a fresh concept that we have seen before, but that hasn’t made its way to a lot of games on the whole. You see, there really are no pay symbols and the base game, if we can even call it that way, is only about you hoping to trigger the gameplay features. This action takes place on 3 reels and 3 rows.

The production values are high in Bonus Only and the game looks like an old-school slot machine that you have to mechanically operate to spin. It’s all golden, too, which adds a bit of glamor to the mix. There’s also a lot to be said for the visuals that are in play during the gameplay features. They are splendid, so the bottom line is that Bonus Only really is easy to look at!

Mathematically, Bonus Only has a low volatility level and it’s perhaps more subdued than you’d expect.

The jackpot is 1,750x your bet, and you can play for stakes between £0.09 per spin and £180 per spin. That’s will please both low rollers and high rollers, so everyone can jump in and give Only Bonus a shot. Finally, the slot’s theoretical RTP is 96.21%, which is a notch above average.

Bonus Only Slot Features

Since there are no pay symbols in Bonus Only, you might be wondering how exactly the game works. Well, it works just like normal online slots, the only difference is that there are no regular payouts. Instead, you have to trigger the gameplay features by finding the right special symbols.

There are four special symbols in total - Vegas symbols, Macau symbols, Monte Carlo symbols, and Dice Wilds. To trigger one of the gameplay features, you have to find 3 matching location symbols. Dice Wilds can substitute for any of them and even add extra dice rolls to trigger, though they can appear only on reel 3.

Once you trigger one of the three location gameplay features, you’ll go to a special board game that will have you rolling dice while collecting bet multipliers. You’ll always start with at least 2 dice rolls, but you can win additional rolls by rolling doubles. You can also land on . spaces to get to pick a card for a special reward.

It’s worth noting that there are differences between the three locations, even in the potential multipliers. While Vegas multipliers go only to 40x, Macau multipliers go to up to 80x and Monte Carlo multipliers go to up to 400x. Once you finish a bonus round, you’ll collect the total bet multiplier and go back to the base game.

The hit frequency for these bonus rounds is 1:15.

Review Summary

Bonus Only might be a niche online slot, but it’s rather intriguing in that it focuses completely on its gameplay features. There’s a bit of a variety in those and that’s great to see, though much of the game is spent just getting losing spins with no triggers. That makes for a grindy experience that only bursts into life every now and then.
