- The Kairos Klepsydra was released along with a 25% reduction in time for everything for Kairos' Birthday.
- The Kairos Klepsydra was given to every player as a free gift which appeared in their Social section of the game.
- This was repeated during the second Kairos' Birthday and any player who had one already received an additional Kairos Klepsydra.
- The Kairos Klepsydra does NOT increase your chances of obtaining artifacts.
- There was a mix-match between the twin dragon and the Kairos Klepsydra. Players who received a twin dragon upon opening the park on March 4th got a dragon from Backflip instead of the decoration, even if they already had Kairos in their park.
