About Dragonarium, from BoardGameGeek:
Dragonarium is a tile-placement game with drafting and resource management elements. Players are welcomed into the Imperial Hatchery to construct the ideal dragon-arium. While placing tiles to make connected domains, make full use of elements circling the player board - an innovative resource mechanism - to breathe life into your dragons.
The game is played over twelve rounds. Each player drafts a tile with one or two land types, placing it to build their dragonarium out and up! Then choose one of the land types just placed to activate an element token (fire, water, wind, and light) circling the player board. As the token passes by a row or column, it provides the energy needed to hatch the dragons found on placed tiles.
Once ready to hatch, place a tile on top, releasing it into the dragonarium. The land where the dragon nests, however, allows players to further connect domains as the tile now shares the element of the placed dragon. Aside from being a robust (more traditional) spatial puzzle, Dragonarium challenges your timing for when and where to release your dragons so as to interweave their domains.
