A Mayan-themed worker placement game.
Tzolk'in: The Mayan Calendar is a game from Simone Luciani and Daniele Tascini, published by Czech Games Edition. The publisher's description:
Tzolkin: The Mayan Calendar presents a new game mechanism: dynamic worker placement. Players representing different Mayan tribes place their workers on giant connected gears, and as the gears rotate they take the workers to different action spots.
During a turn, players can either (a) pay corn to place one or more workers on the lowest visible spot of the gears or (b) pick up one or more workers ... [and perform the corresponding action (the longer the worker stays on the Gear, the more powerful the action.)]
