The third race of the 2018 Sand Marble Rally was hosted in Klimduin Brechtdorp. The weather conditions were partially cloudy with a little bit of wind. The sand condition was dubbed 'moderate'. It was the first race to feature a Gimbal (Stabilizer) for the camera.
At the beginning, Ghost Plasma and Red Number 3 went side-by-side for the lead until Comet managed to get in between the pair. Marbly Mcmarbleface and Grasshopper then sped past to take the top two spots. While Ghost Plasma and Comet dropped back and were never a factor again, Red Number 3 quickly recovered as he and Ducktape accelerated towards Marbly Mcmarbleface and Grasshoper. The 2017 runner-up took second behind Marbly Mcmarbleface, but then lost the position to Superball, who had also passed fellow rookies Grasshopper and Ducktape in the split seconds before his move on Red Number 3. Big Pearl then replicated Superball’s action and took third in front of Red Number 3, while Rastafarian completed the top five after also getting past Grasshopper and Ducktape.
The tightly packed top four rapidly distanced themselves from Rastafarian. Superball lost momentum after a touch to the wall and fell back to fourth. Big Pearl tried to take the lead from Marbly McMarbleface but instead bounced off of him and went into a wall, which allowed Red Number 3 to reclaim second. Superball managed to overtake Big Pearl but was re-passed moments later. Off-screen, Rastafarian dropped two positions as Ducktape and Slimer were now contending for fifth. As the race started to come to a close, Red Number 3 launched attempts to take the lead, but was blocked by Marbly Mcmarbleface. The latter won the race 0.13 seconds ahead of the former with Big Pearl and Superball behind. Slimer took fifth from Ducktape in the last possible moment, with Rastafarian drafting them to the line in seventh. Grasshopper took eighth after running in second early on, ahead of Crazy Cat's Eye, Ghost Plasma, Nemo, Comet, Quicksilver, Lollipop, Deep Ocean, Blue Moon, Black Knight and Phoenix. Dragon's Egg in nineteenth was the last marble to finish, more than 2 seconds behind Phoenix. Championship leader Summer Sky was the only marble who failed to complete the course.
