Football for newbies;-)
At level 15 you can buy your own football team for 50k$.
For making it work you have to add 11 players to the roster (by adding them to the field, just click the position and pick a girl from the bench). These players can be aquired from your girls (actresses and hoes) or can be bought for CC. When you recruit from your girls, the girl is gone playing football for good (no return). But her slot is freed for recruiting another actress or hoe as replacement.
The football values (defence, passing, shooting and dribbling) are random with increasing odds for high class chicks. When you don't want to gamble with your newly aquired divine girl, you can send her to the trials (Try her out! Button) for 24 hours. This gives you the opportunity to decide whether she is worth the sacrifice.
Every non-CC girl starts with a value of 40/xxx (CC girls need no further training) with a value of 10 in each category. You can train your girls to improve their values with money until they reach their individual limit. With increasing values you got to pay more money and wait longer for the improvement (or you pay with CC). During the training your girl is allowed to play matches (unlike improving girls in film academy or SPA).
League starts on Monday morning and lasts 7 days. You can play every 30 minutes one match. If you want to play faster you got to pay with ... (CC of course).
When you finish in the first 3 places of your league of 50 players (of all levels), you are rewarded with a cup and some money at the end of the week.
For a draw you get 1 points (but your opponent too) and for a win your receive 3 points exclusively.
Nice bonus is also getting some mojo for winning a match (level of opponent *10), while losing or scoring a tie won't decrease your mojo.
Should be enough info for your first steps ;-)
