Minute Engineering
The 90' Rule and Slot Optimization
1. The 90-Minute Limit
Training in Hattrick is not binary; it is proportional to the time played in a trainable position.
⏱️ 100% Training
This is only achieved by playing exactly 90 minutes per week.
📉 Partial Minutes
If a trainee plays 45 minutes, they will receive exactly 50% of the skill gain. Every minute counts.
🚫 Non-stackable
Playing 180 minutes (League + Friendly) is useless. The system only counts the first 90 valid minutes.
2. Slot Optimization
A slot is a training spot. If you don't fill it with a trainee, you are losing thousands of Zenis.
Mandatory Friendlies: Essential for training your "second unit".
Avoid Repetition: Don't play the same player in both League and Friendly. It's a management crime!
Slot Capacity per Week
| Training Discipline | Max Slots (90') | Training Distribution | Efficiency |
|---|---|---|---|
| Main Skills | |||
| 🧤 Goalkeeping | 2 | 1 Keeper (League) + 1 Keeper (Friendly) | 100% |
| 🛡️ Defending | 10 | 5 Defenders (League) + 5 Defenders (Friendly) | 100% |
| 🧠 Playmaking | 10 | 6 Inner Mids (100%) + 4 Wingers (50%) | Mixed |
| ⚽ Scoring | 6 | 3 Forwards (League) + 3 Forwards (Friendly) | 100% |
| ⚡ Winger | 8 | 4 Wingers (100%) + 4 Wingbacks (50%) | Mixed |
| Secondary Skills | |||
| 🎯 Passing | 16 | Mids and Forwards (League + Friendly) | 100% |
| 🏹 Through Balls | 20 | Defenders and Mids (League + Friendly) | 100% |
| Group & Special Training | |||
| 🛡️ Defensive Positions | 22 | Keepers, Defenders and Mids (Total squad) | Very Slow |
| 🚀 Shooting | 20 | All outfield players (League + Friendly) | Very Slow |
| 🎯 Set Pieces | All | Entire squad (playing or not) | Very Fast |
🔄 Position Changes
If a player plays 60 minutes as a forward and 30 as a midfielder, they will receive training proportional to each position according to your settings.
🧪 Residual Training (Osmosis)
Players who haven't played in trainable positions receive between 12% and 16% residual effect. Note: Osmosis does not exist for Goalkeeping.
Emete's Conclusion
If you want to grow, your goal is for 100% of your trainees to play exactly 90 minutes per week. Not a minute less to avoid losing growth, and not a minute more to avoid wasting slots.
