The are many (no so many way to make credit) in SHL.

1- Confirm your account for a extra 1000 credits

2- Win games

Winning game is the most basic way to get credits, it not a lot (I think they should give more) but it’s a start.

Division Games
For a Win – 10 credits
For a Tie – 5 Credits
For an Overtime Loss (OTL) – 5 credits

3- Vote every days

Another great way to get fast credit is to vote every day, fast and easy way to get up to 60 credit per day.

4- Finish first of your division

Finishing first of your division will get you a lot of money, so fight to be the best.

For finishing first in the division at the end of the season:
a) in League 3: 500 credits
b) in League 2: 750 credits
c) in League 1: 1000 credits
NOTE: Game win credits only apply to division games and no credits are awarded for exhibition games won.
