For robotics and STEM organizers scoring hundreds of runs against the clock
Tournamyx scored the IIUM Robotic Competition — an international championship where 406 school teams competed in sumo, robot soccer, and time-rush events — with attempt-based scoring, custom tie-breaks, and one live leaderboard every team refreshed between runs.

We built Tournamyx for robotics & stem competitions in exactly this situation.
Field guide — robotics & stem competitions
Most tournament software assumes a match: two sides, one result, a win column. Robotics competitions break that assumption on the first event of the day. A time-rush category has no opponent at all — a robot runs the course, the clock stops, and the team is ranked against every other team’s best run. Points-based challenges accumulate across attempts. Only the combat and soccer categories look like matches.
A single competition usually contains all three at once, which is why organizers end up with one spreadsheet per category and a manual merge at the end of the day. The merge is where the mistakes happen, because it is done fastest, latest, and by the most tired person in the building.
Tournamyx scores attempt-based categories natively alongside bracket categories, with custom metrics per event, so a timed run and a knockout series can live in the same competition and the same overall standings without a reconciliation step.
Three category types in one competition
| Category | Scoring model | Ranked by | Structure |
|---|---|---|---|
| Robot sumo | Head to head | Wins | Bracket |
| Robot soccer | Goals per match | Points, then goal diff | Groups |
| Time rush | Timed attempts | Best run | Leaderboard |
| Line follow | Points per attempt | Best or total | Leaderboard |
Two teams finish the course in 12.4 seconds. What happens next is either written down somewhere everyone can see, or it is decided by three judges under time pressure with a queue of parents watching — and whichever team loses that decision will believe it was arbitrary, because from where they stand it was.
Tie-breaks are the single most common source of dispute at STEM competitions, and they are entirely preventable. Encode them with the event — second-best run, fewest attempts used, earliest qualifying time — so the ranking resolves the same way every time and the rule is visible before anyone competes rather than after someone loses.
The same applies to attempt limits and scoring windows. Once they live in the system instead of in the head of whoever wrote the rulebook, the judges’ table stops being a negotiation desk.
In July 2025 Tournamyx ran the IIUM Robotic Competition: 406 school teams from Malaysia and abroad, three categories, 755 matches scheduled and scored live. At that scale the bottleneck stops being the arena and becomes paper — scoresheets walking from the floor to the judges’ table, and a leaderboard that is always twenty minutes behind reality.
The things that mattered were unglamorous: multiple scorers entering results at the same time from different arenas without overwriting each other, standings recomputing as each run finished, and one public leaderboard the teams could check themselves so they stopped queuing to ask. Whether you are running four school teams or four hundred, that is the same shape of problem. The tournament bracket generator covers the head-to-head half if that is all you need.
Questions
Attempt-based scoring ranks each robot on its own runs rather than on beating an opponent. Tournamyx supports configurable attempts per participant, scoring by points, time or a custom metric, and priority-ordered tie-break rules — with presets for points-based, time-based, soccer and sumo categories.
Yes. Each category runs as its own tournament with its own scoring model, and all of them publish under one event on a single public link. Tournamyx ran the IIUM Robotic Competition this way in July 2025: 3 categories, 406 teams and 755 matches across 8 fields.
Tournamyx applies priority-ordered tie-break rules that you set before the event rather than at the judging table. Attempt-based categories can rank on a custom metric such as fastest time or highest single score, and standings recalculate on every saved result.
Tournamyx ran 406 teams and 755 matches across 8 fields and 3 categories at the IIUM Robotic Competition in July 2025, all on one public link. Plan limits are 8 participants per tournament on Free, 64 on Plus and 256 on Pro, and there is no limit on how many tournaments an event contains.
The comparison
Every tournament hits the same five moments. The difference is whether you handle them from a spreadsheet or from one link.
| The moment | The usual way | With Tournamyx |
|---|---|---|
| The schedule | An Excel sheet that lives on one laptop | One link, always current, on every phone |
| Score updates | 47 unread WhatsApp messages on match day | Standings update themselves as scores go in |
| A team drops out | Redraw the bracket by hand, again | Drag, drop — the bracket adjusts on its own |
| “What time is our match?” | Answered forty times, individually | Answered by the link, once |
| After the final | Typos on the printed bracket sponsors saw | A clean recap sponsors actually post |
If the middle column reads like your last event, Tournamyx was built for you.
What it handles
It has to hold up at the moment something goes wrong. Five places where most tournaments fall apart — none of them will be yours.
01/Scheduling
Enter your teams, groups, and courts. Tournamyx lays the whole schedule out across them, round by round — the job that used to eat your Saturday night.
02/Preview
Walk through every fixture, field assignment, and standing before you publish. Spot the imbalance or the awkward matchup while nobody’s watching.
03/Changes
Thirty minutes before kickoff, someone always cancels. Drag the team out, drop a replacement in — the bracket and the public link adjust on their own.
04/Scoring
The scorer picks the match, types the result, hits save. Standings recalculate, the bracket advances, and the public link shows it — before the teams have left the court.
05/Collaboration
Invite co-scorekeepers with the right permissions and divide the venue between you. Every score lands in the same live standings — no “who has the latest sheet?”
Case study — IIUMRC, Jul 2025
In July 2025, Tournamyx ran the IIUM Robotic Competition — the annual international robotics tournament at IIUM Gombak, where school teams from Malaysia and abroad battle in sumo, robot soccer, and time-rush events. 406 teams across three categories, 755 matches scheduled and scored live, every standing on one public link. If it can run an international robotics championship, it can run your Sunday futsal night.
