Third parties will be able to create puzzles (with different settings)! Each puzzle requires a fixed amount of the governance token to be locked while the puzzle is active. After the puzzle is finished or becomes inactive the governance tokens become retrievable. The token required for guessing (and thus also the reward for when it is solved!) can be decided by the third party (there are technical requirements for this, but 99% of the tokens out there are compliant).
Rational: In the current industry we are noticing the problem of tokens that are farmed (prize dumps, not a stable emission, etc.). There are only a few parties capable of keeping their emission (and thus token price) stable. This will provide third parties a chance to burn more of their tokens and at the same time allow their users to have fun!
