We give you Golden Rock Studios' freshly minted 

 - a slot with only bonus rounds!

The old school layout comes with 3 reels and 3 lines paying left to right, with no symbol payouts on the reels. Each win line can trigger its own feature by getting 3 or more bonus symbols on a win line: Vegas, Macao and Monte Carlo. Three matching bonus symbols on a win line will award you with 2 rolls on the given bonus. Meanwhile Golden Dice symbol on reel 3 with 2 matching bonus symbols rewards you with 4 rolls.

The lucrative re-spin feature is all there: score 2 matching bonus symbols on a win line on the first 2 reels, and get an extra chance to trigger with a re-spin on the 3rd reel.

Bonus Only doesn't have base game payouts, which means bonus rounds are triggered frequently. Each bonus consists of a board with 40 sections themed up with the most famous gambling destinations. Bonus payouts are smallest for the Sin City Vegas and largest for the sophisticated Monte Carlo. Simply roll the dice to move around the board - the spot where they land will determine the prize, such as multiplier or extra roll, no win, or move back or forwards around the board.

If you're lucky enough to complete the round on the board all the payouts will be increased by the highest amount on the board! The bonus stops once you're of rolls. Wait no more and try your luck - with Bonus Only you can win up to 1,750x your bet!
