Basically, each troop is worth a certain number of points. You can use barbs, archers, and giants. Each goblin level has an easy mode, medium mode, and hard mode. Each mode tells you how many points worth of troops you can use. For example, the level "rocky fort" lets you use 140 points worth of troops on easy mode, 120 on medium, and 80 on hard. If you wanted to do easy mode, you would put up to 140 points worth of troops in your camps, and try to three star the level. If you only used 80 points worth of troops, you would have beaten hard mode. If you used 114 points, that would beat medium mode. You have to get 3 stars for it to count.
Here is a list of troops, levels, and how many points they're worth. The points are based on the DPS, HP, and range.
Barbarian archer giant Level 4 15 15 60 Level 5 18 18 70 Level 6 21 20 85
