Cool Buck is an online video slot that has been reinvented and upgraded from an earlier classic 3-reel version that became rather popular among slot enthusiasts. Veteran slot fans will be familiar with the Cool Buck 3-reel slot game, and the good news is that a 5-reel version just hit the shelves. Inspired by the Yankee dollar, this video slot even has a mascot named Cool Buck, bringing all his coolness along with him to provide some truly lucrative winning opportunities.

Developed by Microgaming, Cool Buck is driven by five ultra-cool reels with three rows and features an impressive nine fixed pay lines.

Cool Buck 5-Reels - Theme and Background

The background is completely green with a faded, washed out dollar note spread across the backdrop, adding to the look and feel of the game. The background has been kept rather traditional and simplistic with all the focus placed on the reel set. The reels themselves are placed in the center of the screen with thick green lines surrounding the reel set and separating each reel from one other. The symbols are portrayed in front of a dark green backdrop while the control panel received the same color scheme. The betting options are displayed in white, making it extremely easy to see what your bet amount is and how much you won from the previous spin. The sound effects are crisp and upbeat, making it an absolute pleasure to play the game.

As can be imagined from Microgaming, the focus isn’t so much on the graphics and design concept as it is on the mathematical equations behind their slots. They care more about RTP and hit frequency than they do about anything else. The only thing is, Cool Buck doesn’t really wow us with its payouts. What it does have, which definitely works to its advantage, is a great free spin system.

Cool Buck 5-Reels - Gameplay

The game not only provides a thrilling money-making theme with superb graphics and amazingly-detailed animations but also offers a chance to walk away with a decent sum of cash once the bonus features come into play. Like we’ve said before, the principle attractive feature of Cool Buck is hands-down the free spins feature. Let’s look into it.

Wild Symbol

The Cool Buck game logo will represent the wild symbol and can appear as a stacked wild symbol on reels three and four during the base game and will appear stacked on all reels during the free spin feature. It will substitute for all regular symbols to create winning opportunities except for the scatter symbol.

Free Spins

The rolled-up dollar note, known as the Cool Buck mascot, will act as the scatter symbol and displaying at least three Cool Buck scatter symbols anywhere in view will activate the free spin feature. You also stand a chance to trigger the free spin feature by simply collecting a total of 30 pink stars that are randomly displayed on lower valued symbols. Your total pink star amount will be displayed in the top right-hand corner of the screen. Once the free spin feature is activated, you will receive 30 free spins along with a 2x multiplier.

Unfortunately, the free spin feature can’t be re-triggered. However, the fact that you can trigger the free spins feature in two different ways makes it much more likely for the player to trigger it.

Additional Features

Cool Buck is also equipped with a range of additional features including an auto play feature that will allow you to select up to 50 spins while you sit back and count your dollars and a speaker icon that will give you the ability to increase the game volume or disable the sound effects completely.
