For decades, the distinctive “Snicko” graphic has been synonymous with cricket. Whenever batters edged the ball and the naked eye failed to detect it, the technology stepped in to settle debates.
Now, football has embraced a similar concept.
The 2026 FIFA World Cup has introduced fans to a cricket-inspired officiating tool that is changing how crucial decisions are made. During the tournament, Snicko-style ball-contact technology has already played a decisive role in two high-profile incidents—first in Sweden’s group-stage victory over Tunisia and later in Portugal’s dramatic knockout win over Croatia.
Far from being a gimmick, the technology has become one of VAR’s most powerful weapons in determining whether a player made the slightest touch on the ball before an offside or handball incident.
What is Snicko in football?
Unlike cricket, where Snicko relies primarily on ultra-sensitive microphones and waveform analysis to detect faint edges, football’s version combines an intelligent match ball with advanced motion sensors.
The Adidas World Cup match ball contains an inertial measurement unit (IMU)—a tiny sensor capable of recording hundreds of data points every second. The chip communicates instantly with the Video Assistant Referee (VAR) system, registering the exact moment the ball is touched.
Whenever television viewers see the familiar spike on the screen, it indicates the precise instant contact was made, even if the touch is too slight to be seen on standard replays.
Sweden vs Tunisia: The moment football discovered Snicko
The first major talking point arrived during Sweden’s opening Group F clash against Tunisia.
Substitute Mattias Svanberg thought he had scored Sweden’s fourth goal, only for the assistant referee to raise the offside flag. Swedish players insisted that Alexander Isak had made the slightest touch before the ball reached Svanberg, which would alter the offside interpretation.
To resolve the controversy, VAR turned to the ball sensor.
The Snicko-style graphic displayed a clear spike exactly as the ball brushed Isak’s foot. That microscopic contact, invisible in conventional replays, confirmed Sweden’s claim.
The goal was awarded after review, making it one of the first major World Cup decisions to be determined by cricket-inspired technology. Sweden eventually cruised to a convincing 5-1 victory.
Portugal vs Croatia: Snicko saves Ronaldo’s World Cup dream
If the Sweden incident introduced the technology, Portugal’s Round of 32 clash against Croatia demonstrated just how decisive it could become.
Croatia believed they had forced extra time when Joško Gvardiol scored a dramatic late equaliser.
However, VAR initiated a review after uncertainty over whether Igor Matanović had made a slight flick before the ball reached Mario Pašalić.
Television replays were inconclusive.
The embedded sensor inside the ball, however, detected a tiny touch by Matanović, producing the characteristic “Snicko” spike. That touch meant Pašalić had received the ball from an offside position.
The goal was ruled out.
Portugal held on for a 2-1 victory, keeping Cristiano Ronaldo’s World Cup hopes alive while ending Croatia’s campaign in heartbreaking fashion.
How does the technology actually work?
The system is built around Adidas’ Connected Ball Technology.
Inside every official World Cup ball sits a miniature sensor that records movement and impact at extremely high frequency.
The process works as follows:
- The sensor detects every contact made with the ball.
- Data is transmitted instantly to the VAR operations room.
- Officials compare sensor readings with synchronized broadcast footage.
- A visible spike confirms the exact moment the ball was touched.
- VAR uses that evidence while evaluating offside, handball and build-up phases.
The result is far greater certainty during situations where even slow-motion cameras cannot definitively establish whether contact occurred.
Why football needs it
Modern football has become incredibly fast.
Offside decisions often depend on millimetres, while handball and deflection calls can hinge on almost imperceptible touches.
Traditional camera angles sometimes fail to answer the most important question:
Did the player actually touch the ball?
The sensor eliminates much of that uncertainty.
Combined with semi-automated offside technology, limb tracking and VAR, Snicko-style ball detection provides officials with another layer of objective evidence instead of relying solely on visual interpretation.
Not without controversy
Like every major technological advancement in football, Snicko has generated mixed reactions.
Many supporters have praised the increased accuracy and the ability to resolve situations that previously depended on guesswork.
Others argue that football risks becoming excessively dependent on technology, with emotional moments interrupted by lengthy reviews over touches invisible to players and spectators.
The Croatia-Portugal incident perfectly illustrated this divide. While officials could justify the decision using sensor data, many fans questioned whether such microscopic contacts should determine the outcome of World Cup matches.
A glimpse into football’s technological future
The 2026 FIFA World Cup is increasingly becoming a showcase for next-generation officiating.
Semi-automated offside systems, AI-assisted tracking, connected match balls and Snicko-style touch detection are all working together to improve decision-making.
Whether fans embrace every innovation remains to be seen.
But after influencing crucial moments in both Sweden’s victory over Tunisia and Portugal’s knockout triumph over Croatia, one thing is already clear: cricket’s most famous technology has found an unexpected new home on the football pitch.
