- "Being the ball inside a pinball machine must be like being on giant assault course, and that's what faces the robots in our Pinball Warrior Tournament. Oh yeah, and the course assaults back."
- — Craig Charles
The Pinball Warrior Tournament was a side event held in every heat of Robot Wars: The Fourth Wars, based on the Pinball Trial from the Second Wars. Competitors were required to score as many points as possible within the time limit, by hitting targets and clearing obstacles scattered around the arena. The robot with the highest score by the end of the tournament would be declared the winner.
The Pinball Warrior arena featured the following obstacles and targets, each with a certain amount of points depending on their difficulty:
- Two stacks of six barrels (5 points per barrel)
- Silver sphere (25 points if pushed into the pit)
- See-saw ramp (20 points if driven completely over)
- Multi-ball release (10 points for releasing, 5 points for each ball pushed into the pit)
- Swinging car doors (25 points)
- 50- and 75-point targets, patrolled by Sergeant Bash (50 points), Matilda (50 points) and Dead Metal (75 points)
Additionally, Sir Killalot was given free reign of the arena, posing another obstacle for the competitors (although this was not always the case, with Sir Killalot and Dead Metal's roles being reversed during several competitors' runs; Stinger, S.M.I.D.S.Y., Razer, Banshee, Diotoir, Firestorm 2 and Inverterbrat). The pit used in the Pinball Warrior Tournament was located opposite the Floor Flipper, and was much shallower than the one used in the main series, allowing robots to drive out of it if they fell in.

|9||101||Heat A||101 raced towards the barrels and knocked a few over, before trying to take on Sergeant Bash. It couldn't, and so it tried to go over the ramp. It didn't go over the ramp completely, so it didn't score any points. It tried to take on Killalot, before pressing the multi-ball release. It then attempted to get through the car door, but kept into the side of it rather than through it. 101 then managed to hit Dead Metal's target just before its run finished, and so earned 125 points.||125|

- Toy versions of the obstacles used in the Pinball Warrior tournament were packaged with the Pullbacks based on the House Robots; the barrels with Dead Metal, the car door with Matilda, the multiball release with Shunt, the targets with Sergeant Bash, and the ramp and sphere with Sir Killalot.
- The modified car tyres which the points targets were made from were converted into the Pit release button seen in Series 5, Extreme 1 and Dutch Series 1. This can be seen in a few battles, where the '50' can be seen lit up behind the new symbol for the Pit release button.
