You must train a specific number of troops for each level to get spyder points.
You should be aware that the higher your troop level, the more points you gain, and the more training troops are required. Here are all of the details about the troop level and the number necessary:

Level 6: A minimum of 1500 tanks is required.
Level 7: A minimum of 3000 tanks is required.
Level 8: A minimum of 4000 tanks is required.
Level 9: A minimum of 5000 tanks is required.
Level 10: A minimum of 10000 tanks is required.
Level 11: A minimum of 10000 tanks is required.
Level 12: A minimum of 15000 tanks is required.

Note: There is a limit on the Spyder points you can receive daily, displayed on the bar at the top left of the screen: 30,000 points per day.
Remember that the points will reset after the server's daily reset. Then, you will be able to receive the spyder points again for the next day.
