The Create theme has several types of rewards.
1. The Start of day reward. This bonus is given for each new day, starting on the third day, and can contain both new buildings and resources. This reward isn't based on Level or performance and will be enjoyed by all.
2. The Completed activity reward. This bonus is given for each completed exercise and gives coins and the occasional unlocked building. It's not based on Level or performance and will be enjoyed by all.
3. The High bonus reward. If Trainees are highly concentrated and perform close to, or better than, their average best score during an exercise, they will get the High level bonus reward of additional gems!
