Open the chests, get the gifts! Brand new Knossos Palace is waiting as a grand prize: it will drop pearls after the season change 😉

Requirements: level 15.
This offer is available till June, 2 13:00 UTC (9:00 EST).

Gifts don’t repeat!
The grand prize is the Knossos Palace (2,100 coins, 2-4 energy, 1-4 pearls (after the season change) every 16 hours; requires 6×6 squares; can be placed everywhere except the Snow Plateau).
