Portal Stage Event Gives Extra Rewards If Completed Within 3 Days

For the Portal Stage event that gives you 3 days to play, I felt like I'd have to spend money or a lot of time, so I didn't even dare to try. I always just finished by getting about 2-3 eggs in rewards. This time, I completed it and received additional separate rewards. It seems like they give extra rewards in 1-3 tiers based on the time you reach the end reward, and I finished it within a day and got the tier 2 reward. The app has changed to offer more variety in rewards for watching ads, and the events have become easier to play. In a similar event before this, I thought progress got a bit better after watching ads to open the dimensional jar, but in this case, I quickly raised the level of the 'Flower of Life' by watching ads early on, and the tier 1 upper capsule that requires gems or opening free capsules every 3 hours can now be opened by watching ads (there's a daily limit to watching ads, not unlimited), which helped with faster progression. I proceeded by leaving my phone on for more than half a day, having the dragons work (I removed the flowers so they couldn't do other things and only left items that give points), and occasionally collecting the accumulated points.
