Review of Cool Buck

If you are looking to make a cool buck, then perhaps this is the slot for you. This top online slot by Microgaming is available on mobile and on desktop which is absolutely brilliant. I think it’s really great how so many more slots are becoming mobile. Makes it so much easier for us to have a favourite game that we can play on the go, or in the comfort of our own home.

Green being the main colour within this video slot, it’s clear to see that it is based on American dollars. I think that the theme of this game is pretty clear, the symbols consist of stacks of money, rolled up notes and of course the classic symbols such as the King, Queen and Joker. Microgaming does have quite a few slot games that have similar symbols, but of course the theme and background is always different.

Right off the bat I do actually like the look of the game

I like the that at the top of the grid you can collect stars which give you Free Spins if you collect enough. We can talk more about the features below!

How To Play

Cool Buck features 5 reels, and 9 paylines which is pretty standard when it comes to the classic slots. You may jump to the assumption that since it is a rather classic looking video slot that it doesn’t really have any special features, you are wrong. It features plenty of excitement such as Free Spins, Super stacked wilds, scatters and multipliers.

Another objective implemented by Microgaming into Cool Buck slot, is the in-game achievements you can win, along with free games too! Each time you win on a spin with the symbols A, K, Q, J, 10 or 9, you will receive a ‘Free Spin’ star at the top of the screen on the right. When you get 30 of these, Free Spins will be triggered.

Free Spins

You are able to trigger free spins 2 ways. You can either spin and land on 3 or more Scatter symbols, or you can win 30 or more stars in order to trigger the Free Spins feature. You can win these by landing on certain symbols mentioned above. Each star you win adds a free spin to your bank. During Free Spins, your wins are doubled.

Super Stacked Reels

The super stacked reels on Cool Buck can occur on reels 3 and 4 in the base game. During the Free Spins game, super stacked reels appear on all reels. Also note that the Cool Buck symbol is a substitute for all symbols except the Scatter.


After having played this Microgaming casino slot for some time, It is definitely worth giving a few spins on. You seem to get hooked on it because of the star collecting in order to get Free Spins. This was a great element to incorporate because it gives us motivation to win. Give it a try on any of our top rated casinos and you can decide for youself about Cool Buck.
