Doing some quick math - if you perfectly collected all your Castle Points each day, pretty sure you'd get 5,655 Castle Points per week. That's 294,060 per year (or 306,280 if you use the Ad to double your points)
So:
- Lvl 16 desktop: 1,428,700 / 294,060 = 4.8 years
- Lvl 16 mobile: 1,428,700 / 306,280 = 4.66 years
- Lvl 20 desktop: 5,096,500 / 294,060 =17.33 years
- Lvl 20 mobile: 5,096,500 / 306,280 = 16.64 years
Best case scenario is finishing that castle in a little under 17 years...... I'd like to shorten that a little. 17 years is a little excessive
