The third season of the American reality competition series Ultimate Beastmaster premiered exclusively via Netflix's web streaming service on August 31, 2018. The show consists of 9 Beastmaster episodes which were released simultaneously on Netflix worldwide.
 Each country has their own set of two hosts/commentators for the competition. They are as follows:
 Not only do each pair of hosts provide color commentary for each of the nine localized versions, but the foreign commentators also make appearances in each localized version, with their commentary presented by subtitles. If a contestant completes a course, all hosts' reactions are shown on screen. Furthermore, since all host booths are placed, this year, in a circular row on the Ultimate Beastmaster set, commentators from one localization can easily walk over into the booth of another localized version.
 The obstacle course for the competition is known as The Beast, and it is divided into 3 Levels. Level 4 has been added to the Beast for the Finals. Competitors with the highest scores after each level move on while those with the lowest scores are eliminated, with ties decided in favor of the competitor with the lowest time. Unlike the first season (where scores reset on Level 4) and the previous season (where scores accrue on all four levels), all scores reset at the start of the level. The obstacles are suspended over a body of red-tinted water referred to as Beast Blood (except for Level 3 which has blue-tinted water and is referred to as the Fuel of the Pyramid) and housed in a giant steel frame that takes the form of a large animal. A competitor is considered to have failed a Level if all four limbs are submerged into the Beast Blood/Fuel of the Pyramid. Failure ends the attempt at the current Level but confers no penalties.
 This season, in addition to the normal Point Thrusters, a new Mega Thruster has been added, which counts down from 50 at varying speeds, giving the competitors a certain number of points, depending on how fast they hit the Thruster. In addition, a final Point Thruster worth 25 points has been added to the end of every level.
 This season also features a tournament-style bracket, in which two athletes advance from each episode to a semifinal round then to a final round, earning themselves $10,000, where they fight for the title of Ultimate Beastmaster and $50,000. In the semifinals, the top 6 competitors compete, with the top 3 winning $10,000 and moving on to the finals. Competitors must run the entire course (Levels 1-3) in one go and get the farthest the fastest. If they fail once, they are given an extra life they can use to try again from one of five checkpoints throughout the course, but at the cost of the points accrued after crossing the checkpoint. Should the competitor choose not to use it, however, the extra life is then forfeited and cannot be used later.
 In Level 1 all nine competitors compete with the top six scorers moving on. 
 At the end of Hyper Jump, there are two different paths taken, often with interchangeable obstacles, depending on the episode.
 Path 1
 Path 2
 Each individual portion of an obstacle is worth 5 points.
 In Level 2 the top six competitors compete, with the top four scorers moving on. Similar to Season 1, some obstacles interchange with each other.
 Each individual portion of an obstacle is worth 5 points.
 In Level 3, also known as the Energy Pyramid, the top 4 scorers compete, with the top 2 advancing to the Semifinals (3 moving on to Level 4 for the Finals).
 Individual portions of obstacles are worth 5 points.
 In Level 4 the top 3 finalists compete on an 80 ft climbing wall, with the top 1 winning $50,000 and being crowned the Ultimate Beastmaster. Unlike the previous seasons, this level is exclusive to the Finals, and competitors each compete one-at-a-time. Points can only be attained through three Mega Thrusters placed throughout, each worth 250 points more than the previous Thruster.
 At the end of Ricochet, competitors must make a choice between two paths.
 At the end of Mother Board, competitors must make a choice between another two paths.
 Competitors are given unlimited time to accrue the highest possible score, with ties decided in favor of the competitor who finished the fastest. There is no failure condition for Level 4, and competitors may attempt to regain their footing if they lose grip on the wall.
