The Match Engine
The Probability Calculator: How the result is decided.
The Hattrick engine is not a visual representation of football, but a probabilistic simulator that acts as a complex calculator.
1. Midfield: The engine of opportunities
Midfield is the most decisive sector of the game because it controls ball possession.
- Chance Generation: The system generates a fixed number of conventional attacks in each half. The team with the stronger midfield is more likely to receive most of these opportunities.
- Slot Occupation: A 60% possession usually translates to that team enjoying the majority of the match's attacks.
Fundamental Law of the Hattrick Engine
2. Sectorial Duel (Attack vs. Defence)
When the engine decides a team receives an attack, the location is randomly determined: left, center, right, or set pieces.
The Comparison
The attack rating of the team with the chance in a sector (e.g., your right attack) is compared directly against the opponent's defence in that same sector (their left defence).
Goal Conversion
The ratio between your attack rating and their defence rating determines the actual probability of the chance ending in a goal.
3. Ratings: The Key to Success
To understand the engine, you must ignore individual stars and focus on team ratings.
Stars vs. Ratings
Stars only indicate individual performance in a position; ratings are what the engine actually uses to calculate the final match result.
Unlike conventional attacks, SEs are additional opportunities that do not depend directly on midfield strength.
Possession Influence
While they don't depend on midfield, the probability of getting an SE is proportional to possession (55% possession = 55% chance of receiving the SE).
Specialties
These can only trigger if you have players with the right specialties (Quick, Head, Technical, etc.) in the correct positions.
5. External Factors and Engine Variables
Home Advantage
The home team receives a midfield bonus thanks to their fans.
Weather
Affects attendance and the performance of players with certain specialties throughout the match.
Stamina
The engine applies a performance penalty as the match progresses if the player lacks sufficient stamina.
